Check requirements for both the battery and the project.
Works well. I have a potensic P5 drone. It's an older model. So the batterys are extremely hard to find. But with this purchase, I was able to open the old battery and desolder. The old swollen batterys and replaced them with these. Not it works perfectly and lasts longer. If you don't have experience with soldering ask someone who does. But even with basic knowledge I was able to do it. These batteries are good for lots of other projects too. They are a good value. Just check all the requirements for the product you are working with. And don't just throw a battery on it.

Seemingly poor construction with non-functional BMS
Ordered for use with some RAK WisBlock Base Boards. After reversing the plug polarity so it matches the board, the batteries do work to power the board, and charge when the board is connected via USB. Unfortunately in spite of them having a BMS, three of the four batteries have swelled dramatically during the first three or four charging cycles. Straight from the box, they measure 9.37mm thick. The first battery is noticeably bulging and measures 10.85mm after being put through a few charge/discharge cycles over the course of a few days.The second one I tried, in the hopes that the first one was just defective, swelled to 9.8mm after just a single day, being charged by the RAK.The third one I've placed on my bench power supply with the CV/CC settings on 4.2v @ 1.0A (0.5C -- half what the Amazon product page says the battery is rated for; the battery itself is not marked with charge capacity information, nor is it printed on the including documentation. After charging this way for only 45 minutes, while still drawing ~500mA @ 4.2v, it has already swelled by 0.1mm.Will not be buying this brand of battery again, and all of these are getting recycled.

Good quality
Double check polarity otherwise seem solid and so far up to spec. Worst case scenario de-pin and rearrange to match polarity.

Decent for the price, deceptive packaging
Included in the package was a "Buy this at our website and its 20% cheaper!". It wasn't. It was $3.99 more expensive.
