For me balancing is a bit more. I measure voltages of every cell after flight to verify if any has depleted lower. Voltages rise fast but sometimes I can see difference and I charge that cell more mAh running extra 1/20 C and usual 1/10C for the rest.

I have never used a balancer but I think it is wrong to charge thru balancer leads because first and last cell balancer circuit starts to limit their charging when constant current phase reaches constant voltage 4,2V because of voltage drop caused by usually rather thin wire and lousy connectors.
