I would remove the black ground wire in the middle connected to pin 4. What you have works perfectly if you hook up the batteries correctly. However if you wire the XT-60s in series as 1+2, and then happen to hook up the balance leads as 2+1, you will short out a battery. Removing one of the wires on pin4 prevents this problem. Then if it’s hooked up incorrectly, the only thing that happens is your cell monitor won’t turn on. Much safer


hi, but then it will not read out all 6 cells on my lipo alarm?

You have them wired in series twice. Once with the 10AWG main power leads. And a second time with the ~22AWG balance leads. This redundancy does nothing for you but expose a potential risk for a nice fireworks display
