Matches the description. Batteries was all at 4V at arrival. I’ve discharge tested them with 1.4A and each battery gave 375mAh. Internal resistance less than 165mohm. Voltage after full charge drops to 4.12V but they still give more flight time than the original battery. Very satisfied! Recommended
Delivery seemed to take eternity. But when it finally arrived - the drone is alive, alive!!! Good quality, everything works, delivery took more than expected (it was in 2020, though, so it's totally fine).
