High Capacity 6600mAh 6S 10C Multi-Rotor Lipo Pack XT90

I was looking for a decent capacity 6s, hobbyking has a version that is both cheaper and 'better' than this but it's basically always out of stock. This one works fine tho, gives me power when I need it, haven't stressed it much yet, will update the review after a bunch o' cycles.---Update after a bunch o cycles. Continued to provide power and recharges were uneventful, until today. After a morning ride with winter temps here (about freezing), I have a dreaded 0v cell reading and of course my charger says "nope!". I would guesstimate this is after about... 5 months time, call it 40-50 cycles?---Update 2Well it came back to life! I suspect I must have some how pulled too much out of it, even though I have cutoffs in my vesc... Anyway, it came back to life within a week and has been powering me just fine since then. Back up to 5 stars I guess.
