After so many pms I have decided it’s easier just to have one major post I will be making batteries and selling custom boards for the average builder. Currently I will offer 10s configurations if you want a different voltage let me know and I will see if I can accommodate. My boards will be designed completely off your budget and I can do single and dual drive hub or belt drive trains
A few boards I’ve built are posted below along with batteries

These prices will vary based on cells used I currently offer 25r, lghg2, lghe4, lghe2, 30q, and Basen 26650 10s 3p $350 10s 4p $400 10s 5p $450
The battery powered above was done in electrical tape not heatshrink just because of customer preference it does however provide good insulation, I should also mention I use 10awg single core copper wire on top of the nickel strip for better current flow which is included in the price. I use silicone to mount them to enclosure and use rubber sealant on enclosures for weather proofing, these enclosures were not done by me but I will offer my own potentially in the future
