BMS selection
Hi first time builder, I'm looking at making a large capacity 12v battery for my self build camper, at the moment my camper is all electric, running of a 280ah lipo4 battery with a 3kw inverter. This last's me 24h in the winter with my heating on.
I'm thinking of using Nissan Leaf battery packs, each one is 7 to 8v so 2 in series gives +14v, there capacity is +500ah new. I was thinking of doing a 2s 2p or 2s 4p (which would last me 2 to 4 days) or greater.
The pack is going to be in a sealed aluminum case underneath the camper where the spare tire used to live. Case will be lined with polystyrene insulation and a small silicon heater pad for winter.
What I can't find is information on a suitable BMS for a 12v system using leaf battery packs so any suggestions.
Secondly would the case need ventilation holes at the top?
Any other suggestions appreciated.
