I run my Savage Flux on 6s 2x 3s 5000mAh packs.

Ive been thinking about running it in parallel as 3s 10000mAh with the same two packs.... is there any harness i can rig up to achive this?

or cause the flux comes with a series y harness direct from the esc so would i have to change that to a single deans connector from the ESC and make two seperate harnesses for running parallel and series?
