Figured I’d start my own thread on this.
I’m getting 5 brand new factory fresh Gen 4 Leaf batteries for my 2002 e824. Each module is configured as 2P4S so 14.8V and 110AHr capacity. 5 * 14.8V = 74V nominal and ~82V full charge(5 * 16.4V).
For the BMS there is a guy who makes a wireless module which mounts on each battery module and I will post more on that too.
I don’t expect this to make my cart a rocket since it’s in the same ballpark voltage wise but expect to be able to boost the controller for a sustained 25 MPH up small hills and 30 MPH on flat. Given the much higher and flatter discharge curve, it should feel as peppy as it does now right after a charge and during the first mile or two.
One thing I was thinking about was keeping one 12V battery and add a simple 12V charger and get rid of the 12V DC-DC step down. This should keep a little bit of weight in the back and allow for a bit more 12V device power. Actually, a lot more 12V device power.
