I raised it really - touch of a purest point on the circuitly. Without it the balancer is linking the two batteries togther via the leads.

Without it to get the voltage across the first cell you effectively route from the ground on the left battery through the main black line and back down the red line via your "y" adapter. The red wire cuts this out. Less distance less potential for voltage drop...

I type slow...
