Congratulations for the video, very instructive and it has helped me, I have a query: to connect with the Bosh connector of 3-wire battery (positive, negative, the other) as it would connect to a non-bosch ebike motor that only has 2 wires current (positive and negative). I don't have much knowledge of electronics.
Which 18650cell is it? I count 40pcs. Is it meant for a 36v ebike motor? 10 pieces of 3.6V cells in series = 36V Looks like 4x of those 36V groups in parallel = 400wh. 400wh / 36V = 11.1Ah 11.1Ah / 4 = 2770mAh single capacity cells Am I correct? 😊
