I had a solder connection come apart on a 2s race pack a while back and i contacted the company to repair it. They told me it would be $25 plus shipping. I sent it back to them and they repaired it for free and sent it back to me. Might want to call the company who makes the battery and ask if they have a repair program.

I have had internal solder tabs break on me in the past, I simply splice soldered a new bridge of wire across the tabs to fix it. You can see the broken tab across the blue wire here:



I used some electrical tape to prevent any shorted circuits while soldering:



Fresh bridge of tinned braided wire:



Fresh shrink tubing over the pack:

Just to clarify my picture above, the solder tab is broken where the blue wire is attached, you can see the cut in the tab after I have covered all the other connections with yellow electrical tape, before I bridged the repair.

You will need to use at least a 50W iron with a chisel tip and want to solder on existing solder... if the solder tabs have snapped off the internal cells completely, then the pack can't be repaired

too big of a risk to take for a $50 or even $100 battery.

looks like a 10$ lipo to me.. id agree to much risk for a cheap lipo/pass any attempt on fixing not worth it
