There are intellect 2000mah NiMh. They have high drain written on them but don't specify discharge rate. I use a MRC Super Brain 977 at .5A and 25mV delta peak but I stop the charge at 2000 mah to be safe.
Nope, no memory w/ NiMH. Hmmm, I don't know what to tell you. Do you have to charge them frequently? Maybe there's a current draw (faulty circuit), that's causing you to cycle your batteries more often then you should need to.
Maybe something mechanically wrong with your airsoft, that increased the friction? If you put new batteries in, does it start to work again?
