Default Battery wont charge

Ok so I have a Venom Pro Charger and a Protek LiPo 11.1v 3 cell 2300mah and every time I pull it in and try to charge it it keeps saying that the connection break but I have tryed to different plugs and it keeps doing it. My other Lipo which is a protek 7.4 5600mah chargers just fine. I 11.1v has only been charged one time and that was the first time I used it. It goes in my radio it reads 11.2v on my radio. Please help. Thanks

Radio Is a 3pk

One of my batteries does this from time to time. I just wiggle the balance lead and it works after that. Mine appears to have a loose balance wire internally.

The older version of this TX lipo came with no balance wires - I have one like that. Try charging without the balance wires connected at a low rate like 1amp.
They were higher capacity too, think mine are 3000mah.


That's what I do with the one I have w/o balance wiring. You might have a connection prob internally with one of the balance wires. Only way to find out is to open it up and start trouble shooting the wiring with a DVM. Or charge it without...

On the Venom Pro-Charger, if you have a Connection Break, then that is indication there is a problem with the main power leads, not the balance leads.

If the balance lead is not hooked up (or a connection problem) the error would be "Battery Vol Error - Cell Connect"

Venom says you have a prob with the main power wires. I'd look them over carefully. If this lipo is new, sometimes the connections need to be re-soldered. I wouldn't buy a separate balancer for just this lipo.
