I picked up an older Losi mini T with a Novak Spy esc from one of the members here and I wanted to wire it to take LiPos. Voltage wise I know it should work as the ESC is rated to take up to 7 cells at 1.2v (8.4v) but I want to make sure I dont over discharge the cells and wire in a cutoff at 3.4v/cell. Is there a product out there that can do this cheaply? Or is it better to just toss the ESC (and possibly motor) and buy a more modern one with that built in?
