What about this one:

I have a 3S 2900mAh from them (They don't carry that anymore) and it is pretty good. Now I have a 3S 1600mAh from Kong Power and it is pretty small and can fit an 18R. The only problem is that Kong Power doesn't list them anymore in their site and Air Thunder has them, but only is 2S
