Fair point Fred but I tend to worry more about the amps than the volts! The stuff I've ordered should be fine though. Now Ive got to find a charger for my Planet T5 transmitter. Bought 15 years ago and not powered up until today. Only 4 x AA's, very odd in my book!! And a 1.5mm pin in the Tx socket so I'm scrabbling around to find a 4.8v charger with that sort of plug!!
