The methods are the same provided each cell has two wires and the junctions of each cell pair shares a common wire. Leaving the ground off is only for safety when using the main Y adaptor. If you plan to balance and charge through the balance connector only (not using main leads at all), you actually need to use ALL the balancer wires, like this.
I have replaced the taps on the packs becasue i couldent find female taps to match the stock ones. I have one red wire and two black coming out of the pack and into the now hyperion tap. I cant get the balancer (eos610i) to recognize the cells correctly? Dont know what to do. I think i have the wires in the wrong order.
Also i want to make an adapter to charge and balance both packs as one. I dont know how to do this either. I have the 2 female hyperion taps and the 1 male 4s hyperion tap. how do i connect them? What colors go where? And in what order? Also i will be using the main charger wires to do the actual charging. Thanks, Trever
