بطارية 3.7V 650mAh LiPo - Bubblcopter (23812)

Battery went right into the Bubblcopter and gave it a solid second wind—the 650mAh capacity is plenty for those quick indoor flights. Charged up in about an hour, and it connects snugly without any fiddling. Glad I grabbed a spare before the last one petered out.

Was getting maybe eight minutes of flight time with the old battery, but this one easily gives me twelve minutes before the Bubblcopter starts to sag. The 650mAh capacity is exactly what it needed.

Fits the Bubblcopter perfectly, so no fiddling around with adapters or tape. The 650mAh capacity gives me a solid amount of flight time before I have to swap it out, and it charges up quickly. Exactly what I needed to get the copter back in the air.
