Have not tried them myself and won't be paying that much for a maxamps pack, but for $40 I may just want to try a pack from hobbyking.

Yeah, probably well worth experimenting with. Look big and a little heavy - but at the price, might be well worth it. Wonder if the flats will charge as fast as the genuine A123's?

That hobbycity 6s pack does look interesting, but it is hefty at 900g!

Not to mention huge. Gotta tow a trailer behind your RC just to haul the battery around.

i wouldn't be surprised if they were the exact same cells. the dimensions are all the same. the ratings aren't though. i wonder why...:rofl:
