I've got a 300ah 12v LiFePO4 battery in my campervan, which cost $1k.
It is way too much power cause the thing is constantly being charged every time the sun shines and it is pretty hard to use 300ah in a campervan while you're sleeping.
The benefit of LiFePO4 over those AGM batteries, is that you can go to zero. It is worth every $ for that and for the weight savings (in a campervan).
Highly suggest checking out Will Prowse on YT. He's a great resource.
- xattt 3y agoDoes the battery have to be kept at a certain temp, and if not, does it get ruined?
- latchkey 3y agoAll of the LiFEPO4 batteries need to be kept above 0C/32F, while charging. [0] Mine doesn't have an internal heater, so I make sure to keep it disconnected from the solar panels when it is cold out. I live in a warm weather area so it was worth the cost difference for me at the time. Worst case, I can just get a simple 12v heating pad for it.

- xattt 3y agoThanks! I had a (much) smaller LiFePO4 cache battery in my dynamo bike light stored in an outdoor shed that significantly killed its capacity, so I was wondering what people did to manage these types of batteries in outdoor conditions.
- latchkey 3y agoStoring it should be fine. It is charging it that is the issue.
