Which side draws more current?

Every time I go to charge the packs one pack is always less voltage than the other. I have not kept track of if it is the same pack each time, I just figured that one side was driving the servos or something.

Thunder Power Packs have a very good reputation.

The ESC calculates LVC by doing a little math. 3.2 volt per cell cutoff X no of cells. In your case 19.2 volts.

What do you balance your packs with? Balancing is very important.

If your packs are out of balance, you will see a low cell like that.

Astroflight Blinky cell balancers and charge with multiplex LN 5014's. The packs are 5000mah and the max charge on the chargers is 5 amps. So I only charge at 1C. Balance every time while charging. There are only 5 cycles on the packs. The packs perform awesome and I'm not complaining, just trying to protect my investment. It does appear that one of the packs is always taking more balancing than the other.

My Best advice would be to increase your LVC a little until the packs get a few more runs on them.

Also, with the Blinky, let the balancer finish on a fully charged pack.

The balancer may not be done with it's job, just because the charger thinks it is finished.

I think I will increase the LVC like you suggest. I do always let the balancer finish after the charge cycle is over. Sometimes its a while, other times it is not long at all. Upon power up is the ESC suppose to chime the number of cells in series? 6 chimes for 6S.

Yes, one chime for each cell that it sees.

yes but count the chimes!!
if you have a pack with say only 30% charge left it might boot up accidentally with only 5 tones, hence the LVC is tricked into thinking that the pack is a 5s rather than a 6s!!!
