Optionally, i'll be testing a 4s4p configuration of the new Kokam 2AH cells. I create these from 2-cell (or 2s) packs and then parallel 4 of them together. The total 4s4p configuration weighs 30oz and has a total capacity of 8000mAh (8AH). It can deliver and impressive 64amps continuous current.

So, for more money, you can quadruple the flight time with an extra 5oz in weight over the 1950mAh NiMH packs.
