Lithium batteries

[Sonar]

Lithium batteries as the Lesure batteries in a Moho.
Most have a ten year warranty on them. So was thinking on a single large 608 amp 22 volt fogstar battery.

Do members think that two 300 amp batteries would be as good. Or better than a single
And why please .

 

[rugbyken]

first thought is that two batteries gives you a fail safe if one goes wrong still got other, each battery has its own BMS double capacity?

On the telly yesterday a production line sorting stuff off a conveyor belt throwing it back in wheelie bins when all of a sudden bang flames everywhere man blown off his seat because of a Lithium battery and it was small perhaps from a hand tool. I'd look into it before I bought one

Just had thee out of 4 solar lights blow up in the garden yesterday most likely Chinese crap but sold in the uk… eBay as a uk seller noted no address again seems eBay excepts these con artist from China with open arms as they put there address when they open a flea bay account. Then omit the address and contact details.

EBay have turned a blind eye against this practice. And the reply I got from eBay when I reported this was there from China.

There the in thing made by firms that have more than tested them. Unknown names I would not take a second look at.

Probably not LiFePO4.

The lithium batteries in small appliances are entirely different. The LiFePO4 ones used as leisure batteries do not catch fire and explode like that. LiFePO4 batteries are probably safer than lead acid ones, which can give off hydrogen gas and are full of dangerous acid.

Sure you van is 12v not 22v, you would have to change all lights and alternator plus all senders on the engine.

multiple batteries:
1) each is lighter so physically easier to install
2) could be easier to position in the available space
3) if one fails, still have power from the other
4) doubling up on the available charge/discharge levels

single battery
1) almost certainly cheaper than a pair of batteries each half the size
2) less cabling so cheaper to install


As an example of multiple #2 - installed a 300Ah LFP in a Cathago about a week ago. Fitting an additional 300Ah LFP in a couple of days.... There is no way a single 600Ah battery would have the right form factor to fit in the space available, but the two 300Ah butted end-to-end will fit (with around literally 2mm to spare).

Thankyou
Gives me something to think about now.
Will wait until I am nearer the installation time while also noting the above comments.

Not all lithium battery sold as leisure battery are LifePo4, just make sure what you buy is and you are ok. Not all the solar generators/power banks are LifePo4 either, in fact a lot of them are Li-on

Different type of lithium in leisure batteries.

Not all lithium battery sold as leisure battery are LifePo4,

The power packs yes, but "standard" batteries?

Best not to use the term Li-ion because it is a generic term that includes LiFePO4. All batteries, including lead acid, work by moving ions. When marketing people use Li-ion it is usually to disguise the chemistry of their product but they will openly state LiFePO4 when their product has the safer chemistry. In other words if it doesn’t say LiFePO4 it probably isn’t.

You are right that a lot of the power banks are not LiFePO4 but I haven’t noticed any lithium leisure batteries that are using other chemistries.

Yes Steve, I have seen posts with pics where the batteries are lithium but not LifePo4. I thought we had seen this on WC but you asking makes me think is saw it elsewhere.

New one on me but not doubting you. I have seen cylindrical and prismatic LiFePO4 cells but not other types.

It was last year but I don't remember what forum or who posted. Cant remember if it was someone bought it and fitted not knowing or if it was supplied like that in the van.

Certainly a few (no great amount though) use repurposed car battery as well. That is probably not vans though, more Luton conversions/horsebox/wagon conversion. There is certainly non LifePo4 in the wild

22v ?? Do you mean 12 or 24v? Think you will need an engine hoist to get a 608ah in.
What is your current setup?
Can your existing dc to dc and solar chargers work with lithium?
Do you know the load of all your electrical devices?
I've got 2, 12v 280ah Fogstar batteries in parallel. Very happy with them. My back wouldn't maneuver anything bigger.
I use an induction hob and microwave mainly for cooking but do have a gas oven.
I could be stationary and off grid for a good 5 days.
Batteries are charged via a 30a dc to dc charger and a 360w solar panel.

Recommend 2 smaller batteries in stead of 1 big one for ease of fitting plus a bit of redundancy in case one fails.
Son had issues with his 2 Roamer batteries and they had to be returned. Roamer collected and returned each battery in turn as he was living in his van and couldn't be completely without power.

I've got 4 single 100amp lithium so we'll covered

I would agree with that. Stating LiFePO4 is usually a premium marketing opportunity when your rival products don't have them.

608Ah Lithium would only be around 45Kg. I put a pair of 160Ah Lead Carbons into a Burstner a couple of weeks ago.... 42Kg each
