HOW TO: DIY SURRON BATTERY but a DIFFERENT WAY

Probably a new and little more professional way t build a lithium battery pack yourself. And a quite fast one too. This is my second battery i build for the surron. I don't like the "normal" way of spot welding on the positive and negative poles, because its very hard to service such a battery and the spotwelding on the negative side can be quite risky. So i saw the stark varg battery video, which brought this idea to my head. I started design some PCB's and here we are, a fully functional surron battery. It even fits a bit better in the surron than the other i built. Specs: Cell: Molicel P45B 21700 21S/10P = 75.6V/45Ah/3,4kWh Max Power in theory: 34kW BMS: ANT BMS 220A
