I'm new at this. I have a nanotech 4s 5000 mah 65-130c lipo. I have an accucell6 80 watt 10 amp charger. It say's that I have a resistance of 4 on cell 1 and a resistance 1 on the other three cells. Is this ok or should I be asking for warranty. The battery is 3 weeks old with about 7runs on it. Thanks for the help guys.
