I have 2 full Leaf packs in my truck. Since my motor controller does both driving and charging (and regen, which is essentially charging from the motor) there are no diodes, the two packs are always in parallel. I did put a 200a fuse in each parallel string so that a failure in one pack or a short in the controller, leading to excessive current, would blow one or both of those fuses. Cor
