How To: Make a Y Balancer Harness

The only way I'd parallel charge is 1) if the packs were always hooked in parallel when run and charged since they were new, or 2) balance offline (not hooked to a charger) in series first. Once all cells are balanced, then hook them in parallel to charge. Kind of a PITA IMO.

I want to build a saddle pack for a micro vehicle and due to space constraints I would like to solder the main wires together to make a 2s 2p
7.4 pack rather than making a paralell harness I would also like to balance via a 4s align plug to make it 2am in the morning proof can you advise which wires would need to be connected to the 4s balance tap and in which order packs are new Identical and balanced
