ADD A LOW VOLTAGE CUTOFF!!ironically I'm just about done printing a M12 adapter and inline fuse holder to throw at my sons' 6v quad to hopefully give it a little more oomph. It barely moves when he gets on
just crossing my fingers I don't smoke a battery having no regulator or anything on it. If I smoke the quad, owell, he'll get an upgrade.
I ruined an m12 battery doong exactly that. Repowered a PW, kid discharged battery till it stopped moving which took the batt too low and it was unrecoverable. I tried all the tricks.
