The batteries worked perfectly as a replacement and they lasted longer the batteries that came with my Rc car. The size fit most of my Rc cars but were to big for one .

These are great batteries, holding up charge well. My pillar lights last through the night now. Highly recommended.

I have a lot of older Bluetooth speakers that couldn't hold a charge for more than an hour or so. The batteries in these devices decline over time and are useless after 2-3 years. My devices had 2000mAh batteries in them so I decided to double the capacity reducing the amount times the device has to be charged. These worked perfectly. The form factor was larger so I had to make a few modifications to accommodate the larger size. I had to extend the wire leading to the battery as the wire on these were two short. This was easily accomplished with a soldering iron and some heat shrink all available on Amazon. Now both devices are working and stay charged about 24 hrs. at half volume. This is a much better option than throwing these speakers away and buying new. Better for the environment and pocketbook if you know a bit about electronics. My biggest question to these Bluetooth speaker manufacturers: Why do you put batteries in these speakers that don't last at least 12 hours? Why don't they use batteries that can be easily replaced like SoundBox? Batteries accessible via a user accessible compartment... It's probably because they want us to buy another one after the life of the battery is exhausted. This is the solution to save them.

Appears to be a good battery but I returned it because it did not have the connector that my drone uses. I will reorder and get the correct connector that fits my drone

This battery is twice the size I thought it would be and is no good for what I need it for.

I took a chance this battery would work as a replacement for the dead one in my X-Sense driveway sensor. The battery fit the available space exactly but does not have the correct connector to directly plug into the sensor. I was able to make it work by cutting off the attached connector and splicing the connector from the X-Sense OEM battery to it. The sensor is now returned to service and working properly. Please do not attempt a modification like this unless you have the correct tools and accept the potential damage you can cause to your sensor. There is limited space in the sensor case so you will need properly sized crimp connectors and heat shrink tubing to protect the circuit board from contacting the splice.
