Default LiPO Cell Definition

I have read that one individual used a Thunder Power 7S 2P 4000 mAH LiPO pack for powering a Hacker A20 12L outrunner motor. I looked in the Thunder Power web-site but do not find such a pack listed. Could this be this two packs connected in series, a 3S 2P 4000 mAh pack and a 4S 2P 4000 mAh pack? If so, what does one use to charge them at the same time if they are cell balance charged. I am not that familiar with electric flight so I don't want to spend money only to find that what I bought does not work properly or together. I have looked at several other web-sites that carry LiPOs but have found nothing. I would appreciate any and all help you can give to me. Thanks.

If it was a 7S2P pack that was most likely just as you said, a 3S2P and a 4S2P set of packs. You could charge them as one pack and use parrallel balancers to balance. It would be easiest to balance before or after charging. Two Astroflight Blinky's would work.
