Ah ya, sorry, see what you mean.
I'd still have to use a series y-harness to feed the Eagletree and frankly, there isn't much room in this area.
I've reduced the number of Deans and cable by converting the Flux to a single Deans which runs right out the Eagletree leaving me only having to use the one Harness to series link the batts.
It would have been nice to leave the Flux as stock though, I would probably have gone with your method had I realised earlier.
