I think I am going to get 2 of these: https://www.us.sokbattery.com/product-page/sok-12v100ah-lifepo4-battery
Advantages I see: 1. Two of them means a dead BMS only takes half the bank offline, not 100% of your power. 2. They have heaters for the very rare times the cabin might be below freezing. 3. They have Bluetooth for access to the BMS. 4. I saved the best for last, if the BMS craps out or you just want a better one, just open it up and replace it! This is NOT possible with most batteries unless you cut them apart. 5. See 4, a dead cell can be replaced. Joe Della Barba Coquina C&C 35 MK I Kent Island MD USA
