Yes, sorry! Version numbers. I am trying to interrogate the vans original 24 kWh BMS so I can fit a 30kwh BMS and have it work.
I am removing the 24kwh battery and replacing it with a set of 60 ah pouches configured 96S4P.
As they are NMC pouches, I am assuming that the BMS from a 30kwh Nissan battery will work better in the new system, which will in effect be exactly the same as the original Nissan system, just circa 85 kWh. It is a ENV200, and the battery is from an IPace. ENv200 has aircon derived battery pack cooling as standard
