Don't give up yet....These have no voltage at all??

These should have a small pcb inside where the cells are series connected together and where balance wires originate. There have been issues with the connections on that board or with traces between connections. Carefully open the wired end up and start tracing back looking for voltage. When you find voltage, work back and isolate where the open circuit occurs.

Depending on what it is, you should be able to fix it.


Everyone buying these, check voltage immediately when you open box! If thera are probs, anything you do beyond sending them back basically voids any warranty....
