sea jump 2PCS 7.4V 1000mah Lithium Battery for UDI U818A Plus U49W U49C AA818 Quadcopter Spare Parts UAV Battery

I have been using these for a few hours. I have timed the duration of use and both of them get over 15 minutes per charge. I have used them in light winds and still get no less than 15 minutes. They take too long to charge but they do work as advertised. Came back to order another battery and an extra charges. They are exactly like the battery that came with my drone. I will report back my experiences with these batteries.Would recommend these all day long.

These batteries were the same as the original. Working so far, but have not been able to perform stress test and obviously no aging effects so far.

These worked as well as the original battery supplied with the drone.

Great replacement
