Anyone else having a problem with these things overcharging/dying? My buddy killed his riding without his light on, so I kept my light on, and it still melted! My tail light was burned out, but still, running the headlight should have kept the pack from overcharging you would think. I guess I should disconnect the stator wires when motocrossing during daylight hours... any thoughts? also anything special about these battery packs? Couldn't I just wire 10 AA nicads in series and be good to go?
