Portable Power Packs - LifePo4 Battery Boxes -- How I done It --

[Dellmassive]

I'd tend to agree with Mick,. The delta 2 is rated for 3000+ 100-0-100% charge cycles and offering 10yr warranty.

Whatever you do with it your going to get 10 years worth of use.

So I'd bin off the 20-80% and go full pelt 100% -0% or 100%-10%

I'd be plugging into the mains every now and again to for a full charge.

It seems like your running the unit just outside it's operating limits, with regards to very low loads for extended durations.

And very low recharge sessions using short duration low powered solar.

Maybe give it ago for the next two weeks, adding a mains charge every now and again with the normal 0-100% setup.

That's how I run mine.


Though agreed it's not good to fully discharge down to 0% every time.

I normally don't run down below 10% if I can help it.

 

[Mick]

Thanks for the input, it makes a lot of sense. Interesting that it applies to your house battery also. Is that charged by solar?

In my emails with EcoFlow when this first happened, I explained how I was using it - solar plugged in permanently and regularly charging stuff from it - and asked if that style of usage might be a concern. I was assured in the reply that it wouldn’t and in the very next paragraph advised to not let it discharge completely and set it to 20-80%.

I’m beginning to understand now, that I need to recalibrate the SOC quite regularly if I am going to use it as I have been, and that will mean a complete discharge followed by a full charge. Not quite as fit-and-forget as I had expected.

My house battery and car both charge from solar and/or the grid. The priority for my house Solar is set to house load then house battery, car and then grid. My car charger can be set to divert Solar to the car instead of the battery but the house Load is always 1st dibs.

My house battery will not allow discharge below 4% ever except on re calibration when it goes to 0%. They clearly state below this 4% level can lessen battery life. I’d set the floor at 5%.

Last I checked, it was still at 1% and running the 800W radiator after several hours (though the heater cycles off regularly).

I think I’d be sending that back or demanding an engineer visit TBH. If you can’t rely on the unit SOC figure you can really screw up that battery.

 

[Shaun Witts]

I think I’d be sending that back or demanding an engineer visit TBH. If you can’t rely on the unit SOC figure you can really screw up that battery.

That’s partly my concern. But if the SOC is derived from the BMS, which drifts over time, then surely that is the way it is designed? After all, we’ve agreed that the SOC needs calibrating every so often.
This is the same behaviour during calibration as last time, when it wouldn’t charge above 30%, and which I reported to EcoFlow (that it stayed on 1% for several hours while an 800W heater was plugged in), and they never commented on it. Anyway, it appears to discharged to zero now, so hopefully tomorrow is a sunny day…

If your at Zero then you must stick it on the mains to 100% otherwise the calibration won’t/may not happen.

 

[Dellmassive]

@Shaun Witts so if the unit still outputs power, and will take a charge from the solar during the day....... When the BMS soc has drifted out of wack.

Is it a problem that the BMS display is out?

Ie if you just totally disregarded the fact it had a SOC gauge and just used it blind would that be a problem?.

The only issue I foresee with that is the possibility of it running flat, but to overcome that you could just fully mains charge the unit before the important event.


..........

I don't see the BMS drift as a problem.... It's simply that your drawing such low loads that it can't register them... This is the same across all the Portable power packs I have and tested.


And it the same with the lithium leisure batterys that have internal BMS.


Look of the drift of my Roamer lifepo4 over this weekend.

The Roamer app shows 99% (BMS min @ 500mA)

.




...



Yet the Victron smart shunt shows 94%(BMS min @ 100mA)

.



.

That's 5% drift over 2days.

On a 240Ah battery, 10% would be 24ah, so 5% is 12Ah.


...

That's just how It is....


So if you manage your expectations in regards to the SOC display, and ignore it....then there shouldn't be an issue.

I think that as well as ignoring the SOC display, I would also need to ensure that the charge limits were set to 0-100%. As I discovered yesterday, when the discharge limit was set to 20%, but the SOC was showing 6% (which I believe actually equated to 100%), it wouldn’t power anything.

Gotcha 0-100% settings.

We'll give it a go and see how you get on.

 

[Mick]

So that's my Ecoflow Delta 2 ordered with a bag. There was a £50 discount for signing up to an account. No idea on delivery times could be up to 10 working days.

Now I have a shedload of points that I'll probably never use. I can happily, redeem them, get the £50 discount code sell them to anyone on here at a greatly reduced rate. You just need to buy something over £100 or join with like minded peeps to get stuff between you up to over a £100. All proceeds go to the Bala, summer, autumn camp firewood funds . Or Lisa's gin

 

[Mick]

I've just received a DPD tracking number telling me it is coming but they haven't received it yet. Any idea how long after that it will actually arrive? Not convinced it is being sent from within UK.

Mine arrived quicker than I expected. The solar panel arrived within a week, but the power unit took a few weeks longer, but still ahead of the expected date.

 

[Lord Mfwic]

I ordered my Delta 2 on Wednesday afternoon and it arrived on the Friday, so 2 days later.
@Mick I also got the message from DPD like you and it arrived the next day.

 

[Mick]

Yep I had a message last night it’ll be here on Monday.

RIVER mini has a 210Wh capacity. That’s roughly 58400mAh. In other words, it's much larger than a powerbank, and much more portable than most power stations. The goldilocks zone.

RIVER mini is 2.85kg, light enough to throw in your backpack and take anywhere.

RIVER mini has a 300W output (600W surge); that means it can power 99% of your devices such as phones, laptops, lights, and fans. However, you can check what wattage your device uses to confirm compatibility.

RIVER mini supports solar charging, ideal for camping and the outdoors. It supports up to 100W of solar input charging to full in 3–6 hours. Just make sure your solar panel hits these specs: 11–39V, 8A, up to 100W.

here it is , with next day delivery . . .

ECOFLOW River Mini. . .

.

i comes in a nice sturday box . .




.


.

the accessory pack comes with a

3pin mains lead.

XT60 to MC4 for Solar panel input (100W max)

XT60 to 12v socket for car charge input (100w max)
...



..

out of the box it comes 30% charged.

on the front we have the USB A/C and 12v socket ports.




..

on the left we have the 240v 3pin socket for mains output . . .

but also the IEC 3pin mains input and 12v/low volt inpout XT60 ports,

behind a rubber flap.







..

the oposite side houses the cooling fan . . .




.

round the back was a nice surprise that the online pics didn't show very well . .

there is a handle sort of thing. . . or at least a place to grip the unit.


on the new River2 version they have a proper handle. - a nice upgrade but make the unit larger.





checking out the APP. . .


we see the familary EF layout . .



a quick check in the settings show an immediate FW update available. . .





which went through with no problems. . .







very nice. . . . .

the settings page has the similar settings as the other EF units . . .

with many of the options available.

ECOFLOW RIVER 2 MAX

the latest addition to the Lifepo4 family. . .

yep thats right. . . the River 2 range is LPF ( lifepo4 ) cell tech.

not the NMC cell tech from the previous range. . .

that means lighter, and a 10year life expectancy with the 4000+ charge cycles to 80% SoH.


Awesome !!!!

purchased direct from EcoFlow UK it arrived in two days.

i managed to use some loyalty point and got a discount,

plus used points to get the EF River 2 bag/backpack free. ( more ojn that later. )

this is the unit:




nicely packaged as usual.



we get the unit, a user guide and these cables. . .




but no solar MC4 to XT60 that im a bit miffed about. . . so you will need to buy/make your own.

( i already have a couple from other EF units)


the unit is the same form factor as the baby bro that i have, just slightly larger.




i like the details sticker that shows the input specs, which is good.

so for solar we have 11-50vdc range upto 13A - nice.



the unit has rived with around 30% soc.

the screen is nice and visible in strong sunlight.




the first thing to do is add it to the APP and check for FW updates. . .




this is the EF family on the APP. . .



there were about three FW updates that self installed once selecting the update button via the AQPP.




gob done . . . .
