5PCS 3.7V 680mAh 1S Lipo Battery with Molex Plug and 5-in-1 Charger for Wltoys XK K110 K110S V977 V988 V930 Q282 RC Drone, Four Axis Aircraft Battery Accessories (5PCS Battery+5-in-1 Charger)

I had ordered these for my E88 drone, which I lost a few days after I ordered these batteries.(Drone decided to ignore the controls and vanished in somewhere on a hill)I did however test them on a mini drone by using zipties and tied a battery on the bottom.The batteries hold charge well, and the chargers included light up red to show that they are charging.Very pleased with these.

These will not work with my drone, sadly. However, they are still decent batteries. And, if you have other projects that need power, it is pretty easy to re-purpose these. They charge well, and last a decent amount of time as well.

These batteries come ready to use, with a charging cord apiece so you can fill them both simultaneously. They charge quickly and the light tells you that they're still charging; when the light goes out, they're done. The box even has instructions for putting them away for long-term storage, which is nice since most of us don't fly our drones in winter weather, so the batteries do sit unused for months at a time. Good, straightforward pair of batteries.

Great for small applications. Battery works very well for my IoT build.

Know why you are buying these before you buy them, these ARE NOT for small whoop drones that have high C rating requirements, these would be great for lower kv motors on quads.These charged up fine. I don’t plan to use this in a drone, but will use them in the RC hobby by using them to power AIO fpv camerasWeight was about 15 gramsPROSComes with 2 chargersDecent C rating for lower end dronesCONSNot high enough C racing for whoop dronesAdditionally pay close attention to the type of connector this has (with Molex Plug), which is the type of plug that comes on most lower end drones (think the $25 to $80 all in one). This will not work with drones by Emax, Betafpv, etc which use JST.In a drone 1s batteries tend to get beat up, since I’m using these in a camera, these will probably last a long time in terms of shelflife.

Was hoping they would fit in a vintage helicopter but alas not. The Aviation club I belong to builds Uncrewed Vehicles so they will not go to waste. They are just as the specs say. Will buy more if we find a UAV to build that can use them.

These are well-made. Great quality Lipo batteries with included charger. I recommend this product!👍
