Just so you know, you can charge at nearly 5C if you really need a quick charge. These types of batteries are relatively cheap and VERY durable and reliable. There is no need to cycle these packs, and they will usually last about 400-500 cycles.

I stopped using them and switched to Li-Ions a wjhile ago, but I still have NiMH and NiCD in my TX packs. That's um...over 400 cycles on the one pack 1100MAH NiMH. I have mostly used the wall wart, but have quick-charged at 5 AMPS a number of times at the field. These things are bulletproof these days and require no special care.

Just fly, if you lose a pack, buy another they are almost as cheap as alky batteries these days if you go to one of the sites that advertize on RCU.
