Anyway, my order arrived in just 3 weeks. not bad. Everything seems fine quality, except one of the 2 lipo's has a problem.[]
I couldn't get any current from it, and it wouldn't charge. Then I happened to squeeze the sides of the battery on the end where the wires come out and it would then complete the circuit. I had already changed the connectors which would void the warrantee, and it wouldn't be worth sending back a $9 battery and waiting several months anyway.

Does anyone think it would be safe to unwrap the battery and see if I could resolder something?
