I just noticed a very concerning problem with my build. I got an Enertion Focbox (4.12), 10S Lipo battery and a Bestech charge/discharge 80A BMS.
So firstly, I just unplugged my balance connector to manually check on the individual cell voltages. All are reasonably balanced (+/- 0.05V), however, they are overcharged, with the max cell at 4.39V! Im using a 42V adapter to charge. Total pack voltage was roughly 43.7V.
Then I hook the board up to VESC tool, and the ESC is reporting 39.5V? What’s going on here? Any help would be deeply appreciated, I really dont want to burn my house down
