Default Can you repair a lipo battery?

I have a Turnigy 2.2 lipo battery that will not charge. The charger gives me a connection error as if a lead came disconnected. My LHS checked the cable and said there is no signal flow through one of the plug wires - can't remember which one) You can get a signal by checking the balance plug however. Their guess is it's a bad solder connection.

Can you re-solder the charge plug wires?

Yes, I"d return it, but I ordered it from HobbyKing which is located in Hong Kong. The cheapest S&H was $14 which is the same cost as buying and shipping a brand new one.

Yes, it can be repaired, but are you comfortable opening the end up with the wires and finding/fixing whats wrong? Can you solder and work with wires and not short the cells out?

These are usually assembled with a small piece of pcb in the wire end - everything is connected to or through that pcb. Sounds like yours has a connection prob with one of the main power leads and needs to be resoldered on the pcb.

I'm confident I can do a good job for sure, but at this point I either try, or throw it away.

Any tips beyond what you already listed?

There are some pics here or in Electric Offroad of a lipo repair showing the end you're going to work on opened up. With no search capability atm, thats not much help.

Work carefully and make sure you don't short anything. Use a DVM/MM and make sure you understand what you're looking at wiring wise on the pcb, then isolate the prob and it should be obvious what's needed. Good luck

What's DVM/MM?

Sure appreciate the advice.

Digital Voltmeter/MultiMeter....something to check voltage with. If you run electrics you really should have one or the other -

Doesn't have to be expensive...... I think I paid $2 for mine from Northern when it was on special.
