RE: Hangar 9 33% Edge 540
My 10s2p Kokam 4.2AH pack is split into two sets of 4s and 6s sub-packs. The sub packs are plugging into Kokam Parallel Connector boards that I split in two using a Dremel tool. Note that the white shrink wrap allows a probe to be stuck inside for measuring individual cell voltage. It also allows me to re-balance the cells, if needed.
I wired the two Parallel Connector boards in series for the 6s + 4s = 10s configuration. Note that one of the Parallel boards has 3 plugs. The third plug is for the Yellow connector to feed a 4s voltage to the FMA Power Force regulator.
The packs sit on a 6"x4" foam pad cut left over from my trailer floor padding purchased at a home improvement store. The foam is very light but high impact meant to walk on for covering a shop floor.
The entire 20 cells can easily fit inside the motor mount box. I'll hold them in place with more foam. After the photos were taken, I added extra wires to the Parallel Connector Modules to ensure a safe 70amp draw and then wrapped them in electric tape so nothing is exposed to short out.
