RC transmitter charging problem
RC transmitter charging problem
I have a strange problem and I'd be glad of any help or advice.
I have a Planet TX5 transmitter which works fine. I've put 4x NiMh rechargeable batteries in it and they also work fine, but I am unable to recharge them actually in the transmitter. It isn't the end of the world to take them out and put them in a desktop charger, its just a nuisance.
I have a smart charger which I bought from Strikalite ( the battery people) and that works fine, but when I plug it into the transmitter charging socket nothing happens, neither the red charging light, nor the green 'fully charged' lights come on.
Before anyone asks I've checked the polarity of the plug and it is correct according to the little diagram on the back of the transmitter.
The only thing I can think of is that the pin in the socket is not making proper contact with the inside of the plug, but its a 2.1mm pin-size plug so I'd have thought it would be ok.
Any suggestions anyone?

Just going through the same thing myself with the same results, so I had a look at the PCB inside and it isn't a socket for a charger it appears to be for a power supply with the charging circuit built in.
I've not got around to putting volts across it and measuring the current delivered to the batteries yet, I'll do that when I have a bit more free time

Thats interesting Mike. Please update when you have the time to check it out.WVLR:102660 wrote:Just going through the same thing myself with the same results, so I had a look at the PCB inside and it isn't a socket for a charger it appears to be for a power supply with the charging circuit built in.

Thanks, that makes sense. I've just looked at the TX manual again ( always a last resort!) and it says, "...use a correctly rated 4.8v charger to charge the rechargeable batteries" .Busted Bricks:102681 wrote:Some transmitters have a diode in the circuit so you can't use a smartcharger. Only a simple powersupply with a low current will work. Not be best way of charging though. Wiring in your own charging socket might be the way forward.
