Fytoo4PCS 3.7V 380mah Lithium Battery for E016H E016F Hubsan X4 H107 H107C H107D H108 H107L V252 JXD385, F180C, UDI U816A, H6C RC Drone Parts Helicopter Lithium Battery

Fine batteries, all in good working order, and performed just as expected - not exceptional, but not bad at all. Charging time and flight time seem about same as the original factory batts

The slowest shipping I've ever experienced. I buy things from China often and they usually get here in 2.5 to 3 weeks. This took about 6 weeks and buy then I didn't need them. The battery life is very poor. My dying 350mah battery that is two years old lasts as long as these do brand new.
