Hi folks, just building myself a battery checker and I was just wondering what load they normally apply, does anybody know? Its going to be for 4.8~6v nicad and nimh.
Many thanks.

The S M Services one applies about an amp I think. That's reckoned to be what a receiver and four servos will pull, but I suppose it can also depend on the type of servos, binding controls or linkages etc......

The Ripmax one that I have has a 6 ohm load resistor.

What type of model is it for? For a sport model running 5 standard servos I'd be happy with 0.5-1 Amp. For a 50cc aerobatic model running 6 digitals I'd probably want at least 5 Amps.

Thanks for that all, thats a big help 1 amp it will be. Its only for my models which are a cougar 2000, cub and a spacewalker so nothing big.
Been interesting playing with one of those cheap battery checkers just to see what the voltage steps are as when I move all the servo's its dropping a couple of leds but thats only 0.2v underload so thats not to bad.
