The measurements were not correct. It was actually a bit larger and wouldn't fit and if it had been able to fitwould have had to cut and solder the smaller connection on. Amazon took the return no problem.

I put these inside my wireless controllers for the nes classic mini. Simple plug, charge and play. Works perfectly. Now the charge will last over twice as long.

Good batteries I used in a plane worked great last about 20 min

Don't use this for an RC car. Going fast causes voltage to drop to zero.

Easy install, a little soldering

good quality

The media could not be loaded. Hello my name is luther lawton if it isn't a problem changing it for I appreciate it.

My small Bluetooth cube speaker battery had long given up the ghost so a full charge only lasted about 15 minutes. The old battery was rated at 450mAH and this one is supposed to be 500mAH in the same package size but I have no idea if that's real or just inflated specs. In any case the speaker is back to holding a charge for several hours and I'm happy. I thought I was going to have to transfer over the old BMS (battery management system) PCB but this new one came with one already attached.

The size is a tiny bit off of what was specified, but still managed to fit it within the space.
