Ok I have a Duratrax Intellipeak Twin pulse charger. On my charger instructions it says it can charge a transmitter at 1.0 A. But thing is it reads 1.0A for 8 cell transmitters. But can I charge my Spektrum 4 cell transmitter with it? Here below I have the specs my charger has. I have the Spektrum DX3S that uses 4 "AA" batteries. Thanks

It is not supposed to. It is 6 cell minimum. I'll charge 4 AA with it if you want and see how it does. I'm guessing it will turn off right away or never.
