Great battery for Bluetooth speaker projects
I'm using this in a Bluetooth speaker project and have amazing results with it lasting for over 5 days on standby and playing for well over 12 hours. I'm very impressed!

Solid capacity and the JST connector fits perfectly for ESP32 projects
These 3000mAh LiPo batteries have worked well in several of my ESP32 and mesh networking projects. The JST 1.25 connector fits perfectly on the boards I use without needing an adapter. The capacity is as advertised and runtime on low-power IoT nodes has been solid. The protection board means I do not have to worry as much about over-discharge in the field. They come with the insulating tape already applied which is a nice touch. I have bought several packs now and quality has been consistent.

Used this to fix an old portable gaming device. Worked well, but a bit pricy for what you get.

Works as advertised. Charges to 4V only.
Yes. Works as advertised but don’t charge to full 4.2v. Maximum I’ve been able to charge to is 4V.
