3.7v Lipo Battery 600mAh with JST Plug 1S Li-Po Battery with X5 Battery Charger for UDI U817 U817A V959 V222 V929 RC Drone Quadcopter 5PCS Aircraft Batteries

Fits my UDI U818A Quadcopter fine and each battery lasts about 17 mins when messing around in my garage. Will prob be a couple mins less when I keep it in the air. Some of my garage time was on the ground and adjusting trim. Happy with purchase.

The batteries worked great the charger 1 quart doesn’t charge not a big deal. I don’t use the charger that came with them anyway.

I've been flying fpv for 3 years now. On and off. Lately my hobby has brought me to RC cars (mostly Rally cars.) But, I wanted to get a new Fpv whoop, so I purchased the BETA FPV AIR 75. This drone is overpowered and almost dangerous. I'm so frustrated because it takes off so quick, I feel like a total noob. Inside, to me a must to power down in pid rates almost to 50-65 range. Just remember outside is a different story with the wind so I have to turn it up. Good luck prospective buyers.

None of the 5 batteries will hold a charge for more than 2 minutes. I charge them the light goes out on the charger put them in the drone and if I’m lucky 2-3 min max. Very disappointed.

Nice set

Long lasting and fast charging workes for drones.

Casi no tienen potencia y se inflan con facilidad

For now, charging worked fine. Other people complained about the charger being too loose or that it would just blink. I have not seen those problems. Batteries were held tightly by the connector (see video where I dangle everything from a battery). I have not yet tested the batteries in a vehicle yet.

Excellent
