ZombieSS's parallel battery harness solution

[zombiess]

I am tired of running my hokey wiring harness and have decided to create a permanent solution. This is a small sample of what I am working on. Each board holds 3 packs and has holes to run a zip tie through to secure the main lead (I have heard some say their leads have come loose over time). I then have up to 5 4S to 6S connectors for paralleling at the cell level. I have a 90 degree connector for one of the ends to run an extension out for balancing / monitoring of each group. I will be reconfiguring some of the wiring that is seen in these pictures for easier routing / color coding. I started off not knowing if I wanted to keep each group separate or permanently connect in series. I'm going to permanently connect them in a 24S series string. Packs will be my Nanotech 6AH 6S packs for a total pack configuration of 100V/18AH. This will be used to power my high speed Cromotor in a custom built frame with a 36 FET controller. My hope is to create a neat wiring package with low resistance to reduce my voltage drop. Wiring is 4 AWG and the pack connectors are 8 AWG solid copper providing a very secure connection.

I thought about making a batch of these for others if there is interest, but assembly would have to go to the end user, I don't like soldering heavy gauge wiring, it's too time consuming. These are setup for 6S packs but could easily be adapted to 4S or 5S by jumping the parallel pads and buying the correct JST connectors. I included holes in the board to allow through hole connection of the wires but decided to surface mount mine for a neater flatter package.

Looking good. I'm sure you could find demand for that here. And if you need some help soldering things together, I wouldn't mind doing that. I enjoy soldering in that capacity but maybe I'm a little weird.
