I have already started designing the layout of a "next generation" battery for my eZuma project. Currently my bike is using 20s17p, which is just adequate but it fit without any issues in the existing battery box. I'm aiming for 21s26p which will require some mods to my center stand and supports to fit the larger size pack. I plan on limiting charging the 21s pack to only 84V which is 4V max per cell. The goal being to never have to worry about overcharging the pack and presumably extending the life of the pack as well. Another goal is to maintain all my existing "72V" accessories as is. I "believe" there are smart BMSs out there that will balance a 21s pack properly @ 84V if you program it to max out at 84V (e.g. via a Xiaoxiang app).
