So I have my batteries set up in parallel to charge just as progessiverc told me. I have 3s 5000mah batteries plugged into the balancing port and also the charging leads. I started to charge them at 15amps and after 22 minutes it beeped and shut down. It gave me this message

"Capacity over"

I checked the volts of each battery and they were all the same 3.95 on each cell.

I restarted the charging process at 10amp and it seems to be doing fine so far.

Any ideas? I just got this charger and am still trying to learn this damn thing..lol
