Probably overkill but I top my batteries off within 24 hours before I fly every time. (2700mah NiMH flight pack and 4x 1500maH NiMH in the TX)

My new TX wont register on the load test volt meter so I am forced to believe the computer in the radio, and since it wont load test Im afraid to use the peak detection charger on it because I dont think the peak detection circuit will work correctly with that silly diode in it.
(Wont remove the diode because A: its a brand new radio under warranty and B: the guys who designed this thing are far smarter than I; there has to be a good reason for it or they wouldnt put it in there!)
