150ah vs 200ah lithium?

[meza]

I'm switching out a knackered 85Ah lead battery for lithium.
My only requirement really is to run a nespresso coffee machine(!), which draws 1360 Watts, so I'm anticipating a 1500w inverter.

I've already got a Renogy 30A DC-DC charger to install. Planning on adding 150-200w solar soon, via the Renogy.

I'm deciding between a Hypery 150Ah or DC House 200Ah battery. I really don't think I NEED that much capacity, but it seems I do need a large battery (or 2x smaller batteries) in order to supply the peak current required for a 1500w inverter to supply the coffee maker - eg around 150amps





There's only £22 price difference to get the 200Ah.

	Hypery 150Ah	DC House 200Ah
Discharge A	150A	200A
warranty	1yr	3yr
Price	£342	£364
Weight	15kg	18kg

The Hypery has a screen on the battery and a power switch - maybe useful and save wiring in an isolator switch? The DC House seems more basic, no display or switch.

Consumers
- Fridge
- LED lights
- Nespresso

I guess with that much capacity, I could look at ditching gas (I have a hob but not installed a gas bottle yet) and use an induction stove or instant pot instead.
Ideally I'd put the battery under the drivers seat, next to the diesel heater - to free up cupboard space.

Overall what advice would you give? Shall I go for the 150A or 200A!?

No one’s ever complained about having too much battery capacity. Just make sure that all the ancillaries/cables/switches etc. are sized to suit.

not sure id choose either of those. . . to have in the same van im sleeping in.?

id be more interested in the safety of the battery,

what cells are they using
what bms are they using?
expected cycle life?
low temp charge protection?
APP for the BMS,?

........


you get what you pay for with lithiums, cheap batterys are normal cheap for a reason.


defo do you research before parting with any cash.

also as a FYI . . . for inverters,

you need 100ah worth of battery for 1000w worth of inverter.

so 150ah for 1500w

so 200ah for 2000w

Cheers Salty & Dellmassive

I went for the 200ah DC House one. It does have a low temp charge protection on the BMS, and I’ll be charging with a Renogy DCDC 30a which has a battery temp sensor too.

No bluetooth but I’d not expect it at this price range. I’ll be measuring battery status and capacity with a coulomb counter and hall sensor - less wiring to do compared to a shunt.

Did a quick test today running a nespresso on the bench and it worked nicely.

It’s a big boy!

Hi sorry this is a few months ago but did you install the 200ah battery and where did you install it? Is is too big to go under drivers seat? Cheers, Nick

Hey Nick,

The battery was slightly too tall to go under my seat - it fouled the bars under the seat when sliding as the heater position meant the battery had to rest on the edge of the seat base which lifted it up a bit. (See the cardboard box mockup). However I think without a diesel heater it would fit as the battery could be placed towards the centre of the base, and also you could cut out the carpet panel to gain a touch more height.



If I could have moved my diesel heater over by a few CM I think I could have fitted the battery in.

In the end I put the battery in a kitchen cupboard and added the rest of the electrical items on a board there… DCDC, inverter, isolator, fuses etc.





Battery is working well. I’ve paired it with a 200w flexi Renogy solar on the pop top to keep it topped up.

And I ended up with a bigger Vertuo nespresso which draws 1.7kW and it works perfectly! ️

 

[NGB156]

Thanks for the info, really helpful and good to hear your set up is working well I was thinking about putting it all in the rear if no room under the seat..I don’t have deisel heater (yet) so was thinking it may fit lying on its side… Is your van a LWB? ( looks like you have loads of room in the back)

 

[meza]

Yeah I reckon on its side you’d have no worries with height under the seat.

Some people put their diesel heater under the van which is a better use of space but mine was already installed when I got the van.

It’s only a SWB but my kitchen cupboards are pretty deep. It did have a huuuuge wheel arch water tank which I removed to make a massive amount of extra storage.

Good luck with the project. What other electrical gubbins are you going for?

Another pic of the other bits getting wired in:

Diesel heater under the van sounds like the way I’ll go. Still in very early stage of planning so just soaking up as much info and advice as I can atm!.. only kit I’ve got so far is the battery and Renogy DC-DC charger with MPPT.. still need to plan what loads, cables, fusing, etc.. (electrical hook up, solar etc.) then cashflow will dictate how and when it starts to come together!
I like the idea of having all in one place like you have - looks good. Inverter looks huge!… didn’t realise they were that big!

That's the 2000w renogy, same as I have. It'll go on the back of a seat base and there's enough room for a factory swivel seat to rotate. Ain't no way it's fitting in the seat base though! A 1000w would fit.
