I have a couple of VX G3 Lipos Power pack Hyperion 3S/11.1 35C 2200mAh that have puffed just a little, I am using a Imax LiPro B-6 Balance Charger my settings are as follows:
2.2A 11.1V(35)to charge them.

It don't look like you are doing anything wrong. All your settings look good. I just don't think that the hyperion batteries are a very good battery. Some are prone to doing that another that comes to mind is turnigy. I have ran both and they do work and will keep working even tho they are puffed a little. We switched to pulse and sure they cost a little more but no more puffing. Batteries are real prone to if you buy cheap you get cheap. In my opinion spend a little more and problem solved. I have some pulse batteries that are going on the third year and are still solid as a rock and I don't put them in storage and discharge them to 4% and do everything wrong to kill them and they just keep working and are as solid as a brick yet.

Are you able to measure IRs? If they are close together and the packs come up together and remain balanced, you should be ok. I have several packs like yours that are puffed, but their balance and IRs are still close. I expect to retire some of them this year.

If the puffing is only there when they have warmed up from a flight I wouldn't worry.

Alot of packs now (Gens Ace, Pulse etc.) have metal plates under the heat shrink so people don't see the puffing and 'panic'!

Just make sure you aren't discharging more than 80% (75% to be safe) of the capacity and store them at 50% charged if you aren't going to be flying the next day.

Another thing is to get a cell voltage checker and check the balance of the pack when it comes off the charger to check just how closely your charger is balancing the cells.

It is far more wise to spend your money on a good charger than waste alot of money on the latest expensive high C rated packs.

60% of the time, it works every time!
