12V , 1 kg 210A. Not what we look for.

Just to give a comparisation.
Bullfrog uses a pair of 5S (18.5V) 8000mAh 30C packs in series.
This gives us 37V with a peak of 320A and a weight of 1.85kg
Bullfrog is a heavy, and uses about 4000mAh in a normal fight. We ran the Moscow event on 5000mAh packs that could kick out more A for less weight. But then the batteries wore out so fast it wasn't fun anymore.
