Thanks JJ. I have seen his post. Very interesting. I'm waiting until the battery pack is in my hands and then I will decide what kind of bms to use. The REC bms he uses is a top contender.
I am reading more and more about how GM handles the bms issue. They seem to count on the cells staying balanced after what I assume is a prebalance.
The voltages look to be a bit tricky too. Each pack uses 12 cells. So it appears so far that 49v is full charge. 38v at low. Makes it awkward to use with most inverters. So I will need a programmable inverter. Of course my morningstar solar controllers will have no problem with it.
Anyway. It's all moot until the battery is on the floor.
