quick question..
i have a 5200mAh NiMh battery 7.2v what charge current should i set my charger to at a maximum???

The first time you charge it I would go 1 amp. After that you can go to 1C which is capacity/1000. So for a 5200 battery charge at 5amps.

thanks for the feed back

Suggest checking temps, some of the really high capacity nimh can be touchy. Pack should get warm, but not too hot to hold. Might need to drop down to ~4 amps, maybe less.
