we already have them in phones, tablets, laptops, vape sticks, Tesla cars . . . . and now cars & Vans.


There have been a couple of versions of Lithium batteries . . . . and some scare stories associated with them.

wiki - Lithium-ion battery - Wikipedia

in a nutshell the previous types had some issues:
liPo (main use in RC) cells needed a fire proof back when charging. (i had one go up in flames after crashing the RC car and the cell went flying through the air and smashed on the conreat, started gassing off then flames . . . . not good!


The new kid on the block is LiFePO4

(Lithium iron phosphate battery - Wikipedia)

its chemistry is safe to use and is looking like a great replacement for your SLA/EFB+/AGM leisure battery setup.

Why Lithium? . . . . well a normal lead acid battery only has 50% usable capacity, that means you can only use 55ah out of a 110ah battery.

so you would need 2x110ah Lead acid batteries to be comparable to 1x 110ah lithium.

extreamly high charge/discahrge rates . . . so you can charge them fast and draw large loads from them without the Voltage sag associated with normal battery. (ie large inverters, pumps, winches, coffee machines etc)

4000 - 10000 charge/discharge cycles - so effectively they could last 10-20years or longer. (lead acid will last 3-5 years)

most have built in BMS (battery monitoring system) and fancy blutooth monitors.

100% DOD - so you can use all the power.

next to no voltdrop or volt sag under load . . . . which is nice.

they are super lightweight compared to standard batteries.

Most LiFepo4 batteries with integrated BMS`s may work fine with your existing charger/solar/dc-dc charger. (But not via SCR/Smart alternator - see later in thread)

Two things to note is that you cant charge them if the temp is below 0degC . . . . some have internal heaters, some chargers like the victron have programable LTD Low-Temp cut outs, so its not realy a major concern. Also most need a separate LBD "Low Battery Voltage Disconnect"

There are some solutions to these later on.

***************************************************************


So when looking for a lithium battery, look for these stats:

How many charge cycles untill 80% health, (cheaper ones have less)
How many real Ah capacity (not equivalent Lead acid capacity)
Integrated BMS? (nearly all have)
Can you add more batteries in parallel/series.? (most are 2-4 max per bank in series, and many more in parrallel)
Can it use a EHU standard charger? (most will, using a lithium profile)
Physical size and dimensions
whats the charge/discharge temp range? (most cant be charged below 0degC)
You may need a LBD (Low battery disconnect)
You may need a LTD (low temp charge disconnect)
Most will self discharge at 1-2% per month
Most like to be stored charged 50-100%
All will be permanently damaged if run totally flat and left without recharge.

******************************************

Charging a LifePo4 Battery:

Most chargers now days have a lithium charge profile.
Which seems to be CC/CV and two stages Absorption and float. And a voltage of around 14.2-14.6v absorption and 13.8v float. (check you battery spec sheet)

My battery spec was to charge at 14.6v .... but my chargers are at 14.2v (default lithium profile).... this hasn't been an issue and the battery charged fine.

So any dc-dc or charger with a lithium profile will work..... technically any charger will work provided its CC/CV and at the correct voltage 14.2v -14.6v ish (check you battery spec sheet),(but it might not fully charge it properly if not set to a lithium charge profile) but Im just a bit happier knowing I had the charger set to a lithium profile. So it doesn't seem critical about the voltage, as long as it's over 14.0v... (infact when charging I never saw more than 14.0 across the battery terminals, because as the voltage in the battery rises to near the supply voltage the current drops off.) ( the charger was putting out 14.2 and the battery was sitting at 14.1v 100% charged)

Also without a DC-DC a large lithium flat battery will cause a massive load on any alternator or SCR as shown on the victron testing video below, so be warned ! without a DC-DC you could damage your alternator/SCR setup . . . Also the lithium's sit at a higher charged rest voltage, mines at 13.8v so you defiantly dont want to add it to a system with a SCR and a AGM starter battery at 12.4V - the lithium will try and discharge into the AGM starter . . . . . so id say a DC-DC is a must for Lifepo4. . . . . some manufacturers say you dont need a special charger and they will charge off the alternator, which is true to a degree, but as you see below victron vid there is a very good chance you will fry your alternator and SCR. The other thing is most Lithiums state the max charge voltage is 14.6v (going above this will damage the battery) . . . . with our smart alternators we see 15.0v during regeng braking (most internal BMS will disconnect the battery at high voltage, but thats a safety thing and not for every day use.) . . . . . So can we use a Lifepo4 battery on a T6 EU6 without a DC-DC charger? - - - - simple answer is no.

My battery started at 12.8v ...
Which was basically about 10% charged.... then showed a gradual rise as it was charging... and ended up at 14.0v..... then dropped to 13.8v after resting a while.

I also tried it on the victron mppt 100/20 solar on the shed.... that worked fine too...... I just changed the battery type in the victron mppt 100/20 menu to lithium....it started charging up go the max current it could....which yesterday was about 8-12amps.

FWIW I'll be upgrading my redarc bcdc1240 DC-DC charger for the bcdc1250d because the new one has a lithium charge profile and built in MPPT, but ill still be using a 3rd party Victron MPPT. also the increased 50A charge rate will decrease the recharge time(running on the OEM 80Afuse/100Arelay / feed cables from the factory SCR setup (fuses and relay have been removed)).

You may need a LBD (Low battery disconnect)
You may need a LTD (low temp charge disconnect)

Why you should not charge a LiFePO4 battery below 0 degrees


If you have a Lithium (LiFePO4) battery, there are some things to consider when charging under extreme temperature
conditions.
Lithium battery manufacturers often state an operational temperature range of -30°C to +80°C / -22°F to +176°F
and an optimal temperature range of -10°C to +50°C / 14°F to 122°F (this varies depending on brand and
model, consult your manufacturer). This is often misconstrued as a safe temperature range for both charging and
discharging, this is not the case. The operational temperature range is referring to discharging the battery only.
Charging a Lithium battery in ambient temperatures below 0°C / 32°F must be avoided. The reason for this is it may
potentially damage the battery and / or reduce its lifespan.

The optimum ambient temperature for charging a Lithium battery is +5°C to +45°C / 41°F to 113°F.

When attempting to charge a Lithium battery below 0°C / 32°F a chemical reaction referred to as “Lithium Plating”
occurs. Lithium plating is caused by the charge current forcing the lithium ions to move at a faster reaction rate and
accumulate on the surface of the anode.

When this chemical reaction occurs, the internal resistance of the battery increases and reduces the rate of chemical
metabolism. This chemical reaction causes a permanent reduction of the battery’s capacity and will continue to
reduce its capacity each time this reaction occurs.

If you plan on using a Lithium battery in a location that may drop below 0°C / 32°F, you must be cautious as to when
you attempt to charge the battery. Simply waiting for the temperature to raise during the day is a simple solution.
Having the batteries mounted in a location that will have a higher ambient temperature than outside temperature is
also advisable.


Having a battery management system that can monitor the batteries temperature will be beneficial and convenient.
With the touch of a button you can see what the standing temperature of the battery is and therefore whether it is
safe to charge.

******************************************************
******************************************************

From my experience these are the IMPORTANT FACTS ABOUT LITHIUM batteries:

DO NOT OVER CHARGE THEM, (USE A CHARGER FIT FOR PURPOSE ie CC/CV lithium charge profile)

DO NOT RUN THEM 100% FLAT, (TRY TO RECHARGE BEFORE 10-20%)

Keep Them Between 20-80% SOC/DOD for max life life expectancy,

STORE THEM AT 50% IF PUT INTO STORAGE FOR A LONG TIME, (2-3months or more)

USE THE CORRECT CHARGER / METHOD, (LITHIUM PROFILE OR SUPPLIED CHARGER)

DO NOT SUBJECT THEM TO HIGH TEMPS (IN VAN/CAR/TENT/CAMPER ETC) (Try to KEEP BELOW 35degC)

DO NOT SUBJECT THEM TO VERY LOW TEMPS/FREEZING (Charging) (IN VAN/CAR/TENT/CAMPER ETC) (below 0degC)

DONT LET THEM GET WET (IE OUT IN THE RAIN) UNLESS THEY ARE IP RATED

STICK WITH A KNOWN BRAND NAMES, - unbranded batterys and cells may have failed quality control elsewhere,

REMEMBER YOU GET WHAT YOU PAY FOR, SO CHEAP UNBRANDED IMPORTS MAY HAVE SUBSTANDARD PARTS THAT MAY HAVE FAILED QUALITY CONTROL WITH OTHER MANUFACTURERS.


STAY AWAY FROM LIPO CELLS. (older lithium tech)

I was wondering when they would get round to offering an all in one LifePO4 option with inbuilt BMS and safety voltage cut off.

I looked at there offerings, but i was put of by the way they had previously had there BMS module and how it interacted with my Votronic system.

The 70ah current draw seems low on the 200 ah, it goes against the 1200va inverter option as that will be drawing around 100ah.

Still its great to see more options out there, i saved 49kg going to a 240ah lithium battery

*NEW* Victron - Lithium SuperPack batteries – an all in one solution

Lithium SuperPack batteries - an all in one solution - Victron Energy

https://www.victronenergy.com/upload/documents/Datasheet-12,8V-Lithium-SuperPack-EN.pdf

These new Lithium-Ion, LiFePO4 chemistry batteries are often an ideal replacement for many 12V and 24V add a small inverter to charge power tools, run a small microwave or travel kettle for example. Using one SuperPack battery it matches well with the Phoenix Inverter VE.Direct 250VA – 1200VA range. Maybe you’ll add in around 100 to 200Wp of solar panels too using a small MPPT.

SuperPacks keep everything in one package, by having an integrated BMS and safety switch built-in. No additional components are needed as the internal switch will disconnect the battery in case of over discharge, over charge or high temperature. Simple, compact and safe.

The Lithium SuperPack
Victron Energy’s recently introduced Lithium SuperPack range comes in the following capacities and voltages:

12.8V & 25.6V Lithium SuperPack batteries:

• 12.8V – 20Ah
• 12.8V – 60Ah
• 12.8V – 100Ah
• 12.8V – 200Ah

Comparison: SuperPack 60Ah LiFePO4 vs 90Ah AGM
Let’s compare the 60Ah Li-ion to say a typical 90Ah AGM battery discharged to the commonly accepted economic cycle life of 50% discharge for lead. That would give us 600 cycles at that DOD for the AGM compared to 2,500 at the even deeper discharge of 80% for the LiFePO4. Already you can see you may need to replace your lead-acid type battery 2 to 4 times as often as the Lithium. Of course loads, operating conditions and calendar life have to be factored in too. Regardless you get the idea – Lithium does more and lasts longer.

The benefits of Lithium don’t stop there though. Whilst LiFePO4 chemistry is considered the safest of them all, it’s worth considering other factors too to decide whether the reduced weight and volume of say NMC is of more importance for your application than LiFePO4 for example. Victron Energy do both types.

as well as above, looks like they have an internal heater (edit: not sure about a internal heater now, but they do have temperature monitoring and a low temp charge disconnect) . . . . look at the usage temp range. (-10C discharge & +5C charge (internal BMS cold weather charge disconnect) so its fine to run inside the van during a UK winter. which was a concern on the smart blue Lifepo4`s)

no bluetooth is a bummer, but hey. its looking like a very feasible AGM battery bank replacement.

[Bryn23]

Interesting about the -40, although that looks like that is just the Storage temp, discharge is -10 C and charge is +5 C

I also noticed that there was a 10% reduction in energy at 0 degrees, but thats not really an issue, as the heater would be running at those temps.

It wouldn't have been hard to offer an bluetooth option, as it would only be a $5 option during manufacture, i guess they still want people to buy their integrated shunt monitors.

i do like the parallel configuration, that allows more flexibility.

Would you need to change your current chargers etc?

 

[Dellmassive]

Would you need to change your current chargers etc?

Most chargers have a lithium charge profile.

The Redarc dc-dc does, as does the victron MPPT and bluesmart charger, so it's a case of check your charger spec.

Though I looks like with the integrated BMS that it's fairly durable and will accept most charge sources.......

Integrated BMS and safety switch The SuperPack batteries are extremely easy to install, not needing any additional components. The internal switch will disconnect the battery in case of over discharge, over charge or high temperature.

Charge voltage, absorption** 14,2V – 14,4V
Charge voltage, float 13,5V
Max. cont. charge current 35A 50A 70A (Lithium SuperPack LSP 12,8/50 LSP 12,8/100 LSP 12,8/200)

**The absorption period should preferably not exceed 4 hrs. A longer absorption period may slightly reduce service life

EG: 100Ah 1280Wh 12.8v LiFePO4
max charge voltage 14.6v
rec charge voltage 14.2v
float charge voltage 13.6v
max charge current 50A

Downsides
Not wanting to sound too evangelical, we also need to consider the few downsides of Li-ion.

• Higher upfront cost and to some extent higher capital risk.
• Charging is restricted to the +5°C to +45° range, subject to an internal means of blocking the charge source when the temperature is below +5°C. Note this is currently automatically possible with Victron MPPTs when used in conjunction with the Smart Battery Sense for instance. Other products are being worked on to achieve this too and documentation to that effect will be updated in due course.
• The SuperPack (unlike other Victron Lithiums) is not designed for series connections.
• The peak and maximum continuous discharge current of the SuperPack range is not as much as some of our Lithium batteries as its related to the BMS and the disconnect being internal to the battery – so do check the datasheet to make sure the current peak and discharge ratings suit your needs – or choose from the Lithium battery 12.8V & 25.6V Smart or the Lithium battery 24V range or build a parallel SuperPack bank.

Conclusion
Whatever your decision when purchasing new batteries, maybe it is time to give the Lithium SuperPack batteries a chance. There’s LiFe after Lead you know – but as I’ve shown that all depends on what you want to achieve. Is it less weight, less volume, maybe it’s capacity or voltage or any of the multitude of factors that go into choosing a battery system.

Whatever you choose Victron have plenty of choice – with a large range of battery types and sizes: Batteries - Victron Energy

 

[Dellmassive]

looks like my preference on these would be:

• 2x 12.8V – 100Ah

or

• 1x 12.8V – 200Ah

depending the sizes stated above and how they could fit under the seats or else where. . . . .

just have to wait now for the release dates and some real world testing and a YT video or 2.

but its looking promising and hopefully cheaper than the current Victron Lithium battery 12,8V & 25,6V Smart range

[Loz]

dare I ask how much these are?

 

[Dellmassive]

dare I ask how much these are?

not sure yet as they have just been announced on Victrons blog,

but in comparison the other ones i was looking at were £1289 for the 100Ah, and you needed a separate BMS too!

Victron Lithium Ion Battery - 12V 100Ah - Smart | Energy Solutions

it seems a ton of cash . . . . . .

but when you work it out over a 10year life-cycle Lithium is cheaper, by 2.4 times (due to the amount of AGMs you need to buy over a 10year ).

based on,

you need 2x AGMS for the same Ah due to a 50% max DOD of AGM.

500 charge cycles of AGM vs 2500 for lithium.


official blurb:


Comparison: SuperPack 60Ah LiFePO4 vs 90Ah AGM
Let’s compare the 60Ah Li-ion to say a typical 90Ah AGM battery discharged to the commonly accepted economic cycle life of 50% discharge for lead. That would give us 600 cycles at that DOD for the AGM compared to 2,500 at the even deeper discharge of 80% for the LiFePO4. Already you can see you may need to replace your lead-acid type battery 2 to 4 times as often as the Lithium. Of course loads, operating conditions and calendar life have to be factored in too. Regardless you get the idea – Lithium does more and lasts longer.

The benefits of Lithium don’t stop there though. Whilst LiFePO4 chemistry is considered the safest of them all, it’s worth considering other factors too to decide whether the reduced weight and volume of say NMC is of more importance for your application than LiFePO4 for example. Victron Energy do both types. These star graphs do a good job of explaining the differences: Types of Lithium-ion Batteries – Battery University

60Ah SuperPack vs
90Ah AGM
Weight
9.5kg vs 27kg

Size (mm)
229 x 138 x 213 vs 350 x 167 x 183

Useable energy @ 25°C
614Wh vs 540Wh

Cycle life
2,500 cycles vs 600 cycles

Cost
x 2.5 (approx) vs x 1
Notes for the table above:

• Useable energy and cycle life are based on 80% depth of discharge for Li-ion and 50% for AGM, these being considered the most economic use of those battery types.
• Higher loads with lead will further reduce available Wh (Peukert’s Law) when compared to Li-ion.
• Capacity is also reduced for both types by temperatures below their 25°C temperature rating (see their respective datasheets)

Make what you will of the above and whilst you are pondering the pros and cons don’t forget to take these additional factors into account for the comparison above.

• Shipping: If you are replacing your lead from 2 to 4 times as often as Li-on and the fact that the lead weighs around 3 to 4 times as much (depends on Li-ion chemistry used) – then do consider the extra shipping costs.
• Voltage stability: The voltage profile is far flatter for Li-ion compared to lead.
• Voltage sag: Subject to the load, voltage sag with lead is significant compared to Li-ion.
• Li-ion has much faster charge times and if charging from a generator it saves on generator runtime.

Other factors to consider
Is the above enough to convince you of why Lithium might be a better alternative than AGM or indeed Gel? Personally I’m sold on Lithium, but if you are not here’s a few things further to consider:

1. A lead-acid battery will fail prematurely due to sulfation if it operates in deficit mode for long periods of time (i.e. if the battery is rarely, or never at all, fully charged). It will also fail early if left partially charged or worse, fully discharged.
2. By comparison a Lithium-Ion battery does not need to be fully charged. This is a major advantage of Li-ion compared to lead-acid which needs to be fully charged often to prevent sulfation.

1. Efficiency. In several applications (especially off-grid solar), energy efficiency can be of crucial importance. The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80%.
2. The round-trip energy efficiency of a Li-ion battery is 92%.

1. The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy are required (battery operating in 70% to 100% charged state).
2. In contrast, a Li-ion battery will still achieve 90% efficiency even under shallow discharge conditions.

 

[andys]

I'm convinced they're a good thing but I don't think they can be justified financially at the moment, certainly I couldn't for my use. Amortising over 10yrs is a bit of a red herring really, I doubt many of us keep a van for 10yrs and yes you could take it from van to van, but then you'd need to put a lead acid battery in the van you were selling therefore adding to the cost. I've never had a van for long enough that the leisure battery needed replacing. My cut-off would be £500, below that I'd go for it, above I'll stick to what I've got.

For most customers running an inverter Quality Source LiFePO4 batteries by POLINOVEL of similar size to lead acid,AGM etc will almost double the time you can run your inverter for. As LiFePO4 batteries can be drained to 80-100% of quoted capacity and will continue to deliver full voltage at much lower state of charge compared to lead acid batteries that drop voltage under heavy loads and reduce voltage progressively from a state of charge below 50%.

The extra Usable capacity of LiFePO4 and the very long cycle life 4-8 times that of lead acid make LiFePO4 cheaper in the long run and much more environmentally friendly.

Over their lifespan 1 x LiFePO4 100Ah battery offers the same usable energy as almost 2 lead acid 80Ah units that would need to be changed 4 x before the LiFePO4 is at 80% of its original storage capacity. LiFePO4 is not 8 x more expensive than a good lead acid 500 cycle guaranteed battery and contains 8 x less plastic than lead acid units.

1 x LiFePO4 battery at 14.6kg replaces 8 x 19Kg = 152kg of toxic lead and concentrated sulphuric acid during its lifetime. With associated carbon emissions to move these over their lifecycle.

Quality Source, buy well, Buy once to last.

I’m impressed with the 240 ah lithium LiFe04 battery we have, so far, we are only 9-10 days into our year long trip.

this thing charges up quick to 100% capacity. We are using 60-90amps a day with the diesel heater, fridge and induction cooking.

Induction uses a fair bit, but it’s nicer than cooking with gas inside and I properly make to much fresh coffee during the day.

Every morning so far has been -1 to -5 degrees, so the heater has been getting used a far bit running all night, the solar helps when parked up, but after driving around looking at places it’s normally fully charged or close to it.

This arvo was the first time we have plugged it in to mains, but as we are parked up for a few days in the one spot and if I’m forced to pay for a powered site I might as well use it.

One thing I wish I did was, if I had planned on going lithium from the start of my build, it would have been to get the biggest charger Votronic made, as these things can handle up a lot of charging amps and would help if I’m only getting less than an hour of driving time.

awsome,

what make battery is it?
what voltronic charger have you got? (dc-dc + EHU?)
what solar have you got ?

 

[Bryn23]

I can’t remember the battery’s name off the top of my head, it’s somewhere in my build thread, it’s an Australian company, but it’s just a rebadged LiFePO4 with integrated BMS from China, like the rest of the Lithium battery’s being released at the moment.

I’m running a Votronic triple charger 30/20/250 unit, gives me 30amps with dc-dc, 20 amps when plugged into 230 volt and max 250 watt panel.

I’m running a 180 watt commercial semi flex panel, I’m seeing getting between 6-8 amps an hour during winter.

I’m also using a Votronic inverter, their Bluetooth module, Jupiter control panel and tank senders, it’s somewhere there in my build thread.

My next build on a Crafter MWB 4motion will most likely be at least a 24 volt 400ah lithium bank, as an off the grid air con solution is needed for some relief in summer around were we live in Queensland, and there are a few 24volt air con systems avail here.

I’m looking forwards to seeing what Dc-dc option Victron offer next year, as I believe they are working on releasing an DC-DC unit.
