Whern I bought my Lithium Iron Phosphate batts this last winter, I opted to get SOK Batteries 12V 206AH, which have a BMS including charge protection below freezing, and have a 7 year warranty. I liked the metal cases, and how they were designed to be repairable, you can open them up and replace the BMS or individual battery
cells, and per several online reviewers, all teh components inside were top shelf. I paid $1100 per 206AH battery
, which seemed fair. The two of them give me 5260 watt*hours of usable power. I have yet to run them below 50% discharge, but they are good for 1000s of cycles to 0% each time. 3 full days and nights of camping in hot weather with zero sun and running our compressor fridge
brought them down to 50%, 1.5 days of sunshine fully recharged them (360W monocrystalline solar panel
with a MPPT controller).
