Any ideas on how to strengthen cell 1? I must be at charge 9 or 10 with the battery. It has 52 charges in total so far. Any help would be greatly appreciated. Here is the Airdata battery log: http://healthydrones.com/main?share=GkeIuS

I think I may of stresesd the battery out from the long distance flight I was doing with it. I had the throttle at full so maybe that is the reason for all the deviations?

It looks like you need one of Rich's harnesses, check out his post here. I have just balanced mine, they work great. It can be done without the harness but so much easier with.
