I'm trying to charge a 16S nissan leaf pack (30AH LiMnO4 cells) using two Turnigy Accucel 8150 8S lipo chargers, but I'm having a bit of a problem. As soon as I plug in the second charger, there is a short, magic smoke is released, and this kills the charger. The first time it happened I assumed I got a bunk charger, since a capacitor was rattling around inside when I got it. But, after I killed a replacement charger in the same way, I'm sure it's my wiring.
I'm sure the problem is somehow the fact they're sharing a connection in the middle, but I don't know how to rectify that. I didn't plan to separate the 16S pack into 2x8S, so there's no way for me to break that connection. The terminals and wires interconnecting the cells have been "potted" with gorilla glue, which would be a royal pain to remove.
I can charge each bank of cells by itself using the good charger, but as soon as I hook up the second, there's a pop, the smell of ozone, one of them says "short circuit error", and then when I go to try and charge again with it, I get "connection break" since it's burned traces on the board.
So, long story short, is there any way to isolate the grounds or install a diode or otherwise somehow prevent this from happening? I'd like to charge all 16S at once, but I have no way to change the configuration from 16S.
