[WIP] Project GTeV - Toyota AE86 meets Nissan Leaf

Nice, haven't seen a custom pouch build in a while. 3D-printing really facilitates this. Remember metricmind going through great lengths 15 years ago machining support structure from aluminium.
Going for 96S?

I was going to use a 3P96S configuration but I'm going to drop it to 2P and probably 104S. There's a company up the road that does a BMS (https://www.prohelion.com/product-category/bms/) that has monitors configured for 8 cells so that would fit neatly. Tell me if I'm wrong but I figure that a 104S will give me a little bit more capacity without an unusable increase in voltage for the Leaf Gen3 stack.

Up to 108S would be perfect for a Nissan Leaf gen3 stack. Even the PDM can easily charge up to ~435v. But 3x96 would still have more cells so more capacity than 2x104.
You could also use Tesla BMS slaves together with SimpBMS to monitor the battery. One Tesla slave can monitor 6 cells and you can have as many slaves as you need. Got them for sale if interested.

Thanks Marty.

I haven't ruled out a 108S, I have the space and one more BMS slave isn't an issue. I have ruled out a 3P config though because it weighs too much, almost tripling the weight of the cells, and the AE86 was a light car (970kg). Also, I don't need the additional range, which was a consideration in choosing the cells, as most of my trips are less than 20km round trips with the occasional 100-200km trip.
