Purchased for xk k100 helicopter. It is very affordable with 2 pieces. It seems that quality control is done firmly, and both arrived at the same voltage (3.89). It is a very good genuine battery.

It is a little shorter than the original XK X100 battery, but it fits just tight. The original one weighs is about 7 grams and this weighs more or less the same weight... less than half a gram than the stock one, maybe the shorter cable. Still didn't tried in the quadcopter to see the flight time... but since it is the some amp's i must get the same time.
