Tesla batteries
The battery modules from the Model S are 24 V, 5.2 kWh capacity.
If I can't get the Tesla BMS to work, there is a replacement available. Overkill Solar's second generation replacement BMS , called Pathfinder, may soon be available. The Pathfinder seems to replace the Tesla BMS. It seems that each BMS can handle 3-16 cells. This seems insane, since each module has 6 x 74 = 444 cells.
Another alternative is the Vero BMS v2. From what I can tell, the Vero BMS plugs into daisy-chained Tesla BMS modules.
