First a shoutout to Thomas Singer, he did borrow me this new, unused Lipo for my tests! I really appreciate this great support!
To be clear right at the beginning, this Lipo does not have 120C! This high C rates are pure marketing. Nevertheless, this battery did surprise me, like it's 1500mAh "brother". The performance within the 1300mAh class of Lipos is really great at higher amps, and even the temperature is under control. Indeed, this battery is even doing well against some of the 1500mAh class Lipos in the ranking.
At the 60A test this battery is also good, but there are some other Lipos that can perform a bit better in this range.
This Lipo does come with a nice feature that I really do like: a removeable balancer cable. If you're looking at a 1300mAh class Lipo, you should give this a try.
