Charge nimh battery

I have a imax b6 and i want charge nimh battery for transmitter (aa battery) but I dont know what value of ampere set

.3 to .5a should be fine. Going to take over two hours based on battery mah

Are you sure?

you can charge at .5 c to be safe. 1 c is safe on larger batteries

That means half the capacity. So a 2,000 mah battery can charge at 1 amp

I try tomorrow, thanks
