I have been using my ac6 charger for nimh batteries no problem.I tried to charge a lipo but i keep getting connectio broke i checked all the connection everything looks good any help . thanks in advance.

I had the same problem with my Ac6 and come to find out it was the balancing tabs that were shorted out. I quit using the chargers balancing and got myself an Astroflight Blinky to balance my packs and the problem went away.

Dam, I hope I don't have that problem when I go lipo....I just use NiMh still, but that would be a bummer...
