All good advice, but I would also suggest you buy yourself a digital load tester and plug it in after charging and see how long it takes to drop the voltage to 4.8v A fully charged 4 cell battery should read about 5.8v fresh off the charger, if not you need a new battery or a new charger. Man you got lucky 2 times you lose control and got it back[img][/img] One time would have been enough for me.
what about this for a load tester?
