So I finally got around to buying a decent battery charger, the Maha C-9000. On the instructions, it states to charge above .3C and but below 1.0C, C being total capacity. I assume this means if you have lets say 2500mAh batteries to charge them at a rate above 750mAh and below a rate of 2500mAh. Is this correct? However, I've heard of the .1C rule, meaning charge at a rate of 1/10 the battery's capacity. Also when discharging, what is the proper rate? I can't seem to find any hard answers for this stuff.
