ORIGINAL: wopachop
The new charger is so much fun. This morning was the first time i got to fly 3 batteries in a row. Been recording my individual cells voltages right after landing and then 15 mins of rest. I dont have the paper in front of me but after about 9 mins flying im in the 3.9 volt range.
Even if your 9v LVC has the resting recovery voltages of your 3S pack's cells at say, 3.17v, 3.13v, 3.03v = 9.33v after 15min. no need to fret ... just don't get in the habit of using 90%+ of your LiPo pack's rated mA/h capacity. The following is taken from the instruction manual of a TP Smart Balancer. So, in this case ... http://www.wattflyer.com/forums/showthread.php?t=60738 ... B: would apply as 3.17v, 3.13v, 3.03v = an imbalance difference of 0.14v.

A: Imbalance under 0.03V: … Allows normal charging.

B: Imbalance 0.03 to 0.2V: Charge at 0.5A to condition/balance an 800mAh and larger pack. Charge at 0.3A to condition/balance a pack smaller 800mAh. Monitor the pack during charging, if the pack becomes balanced during charging, you may then charge with normal rate.

C Imbalance over 0.2V: Battery may require repair, please investigate battery pack or you may attempt to repair the pack by 300mAh balancing /conditioning charge (Please monitor throughout charging)
