Updated the battery to 16.8v nimh 4300mah but it's doing the same thing again! Discharge is fine but on the charge, the charger is turning off and on therefore cancelling the charge. It's a 14 cell pack so ive changed the 10c bit to 14c but other than that everything else has stayed the same (4300mah, 3amps max charge and 5m/vc or whatever that bit is!)
Thanks
Dan
