Cons: -Battery is quite large, but that is to be expected with this good specs

Other: This is a great battery if you can fit this where you need much "juice"

Pros: I bought this battery because of the good reviews that I saw, and I was not disappointed. Unlike some batteries, this one is rated at 2800 mAh, and actually measured just under (~2780) mAh, which is quite a nice surprise. The resistance in each cell was not too far off either, making this a fairly good battery. Surprisingly, the battery came with the Dean's T connector, and not just split wires, so that was a nice addition.

Cons: None that I can think of.

Other: A good battery that actually has the same current capacity as advertised. A nice addition to anyone that is interested in the RC hobby.
