RE: Sweetest Charger Ever!
A link to the specs and a manual will help us to help you. I'n sorry I am not familiar with the charger,balancer,wiring. Most set-ups are very similar though.
Just to be clear on the problem:
You can get it to charge directly, but when trying to charge through the balancer it shows a battery not connected error, right? Hopefully you have both a balance lead and the main power leads hooked from the balancer.
