Czxin 5PCS 3.7V 200mAh Lipo Battery for Syma X11 X11C X13 RC Quadcopter

I purchased these as backup batteries for the zyma D63 Drone Runner. At the time they appeared to have the same plug, however, upon arrival the plugs were larger than expected and wouldn't fit.So I very carefully ground them on my bench grinder until they fit,they're not perfect but they work well.Since the actual replacement batteries for this drone don't come with a plug this was the next best thing.

Seems to hold charge as well as the original battery so now my son never has to stop flying his damn drone, ha

As ordered. Brought joy

Good batteries charged up in no time and they hold a charge.

Thank you. Great communication and product.
