I have a problem I can't seem to figure out. I am trying to charge two 3s lipos on my charger but something is wrong, I nearly destroyed one set of lipo's already because of this so I figured I would post my issue here and hopefully someone here can tell me what I'm doing wrong or why this is happening.

As you can see in the picture I have a 2 3s to 6s jst adapter plugged into the charger (it appears to be wired correctly) and I have a deans plug series adapter (you can see the scorch marks on it)
Basicly if I connect just the series adapter everything is fine or if I connect just the balance adapter everything is fine, but if one is connected and I go to connect the other it shorts out (and startles the crap out of me!).
I have a 2 4s too 8s adapter that I use with no problem with my two 4s packs and thats what has me perplexed, I can't see any difference that would be causing a short on one and not the other?

Hopefully someone here can see where my problem is in the picture????

Hope I explained that clearly enough.

Thanks for any help.
