TOPVISION Drone Battery for X39

I bought to have extra batteries and charger for my TopVision X39-1 smart drone. Came with two batteries and the charger. Does not include a USB power adapter. The charger has four ports to charge four batteries simultaneously (or so I assume). There are no instructions. I used my Samsung 2.4V power adapter to connect the charger. Only two ports will charge simultaneously with mine it seems. I connected four new batteries out of the box to the charger and only three of four LED indicators illuminated, then an LED turned off/on and alternated with another port LED indicator within seconds of attaching all four. The red LED indicator will stop lighting when fully charged I presume. Eventually all the LED charge indicator lights went out after about 90 minutes. Not certain if all four batteries got full charge. Will have to follow up with another review after I measure the time of use with each battery.

Great to have extras, exactly the same as originals, plus a charger that will charge all 4 at once. Now I have twice the flight time : )

I don’t like that you have to pair the remote with the drone

This 4 pack of batteries and charger keeps a drone that drains batteries in the air A LOT longer! Must have!

Didn’t work or charge. Tried to use computer and also a wall outlet. Wouldn’t buy again

I like it fine. I broke the propellers and can't find new ones. If I could get replacment propellers it would still work. If you can't help with the propellers would like a refund to put towards another drone. Thank You.

Good batteries but they only last about 6-7 mins but good enough.
