Loose balance tap? I think
 

I have a Gens ace 2s 4000mah 30c battery that I think the ballence taps are loose. I tried to charge and the charger had voltage error. Tried again and one cell had voltage then it dropped to nothing. I played With the wires and it charged/ballenced just fine.

What's the best way to fix this?? Will they short, puff, or worse because of this?? This is my first time with lipos so be nice..:lol:

Thanks

Anyone?? Are these safe to just sit at home??

I would be greatful for any help!

with out seeing the plug first hand its a little hard to say.
you maybe able to pop the pins out on the balance plug (like on servo plug)
and give them a small tighten with a pair of pliers
i dont balance my lipos (unless needed) and just keep a eye on the cells make sure they dont get to far out. most batteries these days are very good and stay with in .02-.03 of a volt.
if it only charges 1 cell whilst charging it wont hurt the pack,but when discharging it could and probably would discharge the low cell below 3 volts
destroying the pack.
hope that makes sense :weird:

Thanks. I'm pretty sure its a loose wire and not the Plug. I guess I was wondering how do I open up the pack and fix the connection. And do this with out burning up the pack, or anything else.

Thanks

My bad, I thought you ment the balance plug.
I have fixed lipos by resoldering the wires inside the pack with no problems. But if you try that be very carful

What's the best way to open up the case. I assume once opened it should be pretty obvious what needs to be done.

Thanks again
