    Grate batteries for my favorit V977 heli :) Well packed, they come charged to 3.90-3.95V . The charger deliver 4x 550mA so you need min. 2.2A USB adapter to charge 4 battery at once.

    The order arrived fast and it was well packaged. Haven't tried the batteries and charger yet since I didn;t have the chance to go out and use them on my heli. Hopefully everything will be fine

    Love these batteries nice and light, good punch and fit alot of my quads, works perfect for some of my Micro racer drones. Good price also.

    The fit is pretty tight in an XK k110 helicopter. They are slightly fatter to accommodate the extra capacity. (fair trade) I recommend peeling off the wrap-around labels, cutting the battery info section out, and then sticking only that part back on the pack. That makes them fit a little better. The flight time is good, and they have more punch than the lipo that came with my heli, although that may have more to do with age and hard use since I don't have a fresh pack for comparison. Overall,
