I guess I could make it into a 3s pack. Kind of pissed, 5 cycles on my pack too, wires not run through the hold down straps. I'm going to try Turnigy for my next battery. It's a real letdown, all the Gens ace 2s batteries I have are great... Not so good with the 4s hard case.
Exact same problem here, two 4S packs. The solder tab was broken off with about 1/8 inch left. Managed to solder the wire back on with the solder still left on the positive lead. I covered the connection with shoe goo to prevent it from flexing and breaking again. I noticed the case on both batteries wasn't taped to the cells at all. The factory didn't peel off the film on the double sided tape to stick the case to the cells! Easy enough to fix that. Now the case is stuck on there good. At least 5 runs on the packs since repairing with no issues.
