Just got a whole pack from Nissan Leaf 2014. I am planning to use cells in my School bus RV conversion.

I want to use them as a house batteries and use them also for starting main engine.

I took the pack apart which is not a big deal. All cells (modules) read 7.95-7.96 Volt. Originally battery modules are configured as 2S2P I want to have them configured in 7S configuration. So, I will take some modules apart to extract individual cells.

The reason for 7S is here. I bought an efficient 24V 200 Amp military grade alternator (American Power Systems 55i-200ACT-28J). Nominal voltage is 28V.

I want to use a small diesel engine/alternator to directly charge 7S pack. 7s pack has a safe voltage of 4.2x7=29.4 V making some room from 28V charging voltage.

I am thinking about using Arduino board for monitoring/balancing.
