URGENEX 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

By far the best batteries I've gotten. They last at least an hour most the time, great price for the quality. These are small enough I can hide them under my camo nets on my rc tanks. They work flawlessly, charge quick, last long. Additionally, they come with a plug in that immediately just works with my wolfwhoop wt05 cameras so it was very convenient for someone like me just getting into the hobby and having no clue about what to do.

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.

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.

A+ Shipping, everything works as advertised & would buy again!

These are not 600 mAh batteries, not even close, don't even know if they are LiPo, last a few seconds then warning goes off and they run out. You will lose your RC equipment if you run these defective products ... DO NOT BUY .... Amazon should take them off, many many bad review ... I didn't see them until after I purchased, then tried them out ... sure enough, won't hold a charge and are NOT as advertised ... Shame on You URGENEX ... stop selling them !!!! Faulty from factory ... Should NOT be on Amazon ... No Stars

Excellent will worth the cost

These are the perfect replacement for my UDIR/C drone model number U817A. I charged them with my Hitec multi charger where i can watch the mAh. They all charged up to 600mAh. Fits in the battery cradle even better than the originals. Longer flight times (500mAH vs these 600mAh). Great price and fast shipping.

Perfect size, charger worked brilliantly. Perfect size for what I needed!

Excellent
