Review: Good Batteries with a Minor Adjustment Needed - I purchased these 3.7V LiPo batteries for a project, and overall, they work great and deliver reliable performance. The capacity is as advertised, and the batteries hold their charge well during use. The only downside I encountered was that the JST leads were reversed compared to my setup. While this could be an issue for some users, the good news is that the leads can be de-soldered from the pads and replaced or swapped with the correct leads. It’s a bit of extra work, but if you’re comfortable with basic soldering, it’s a manageable fix. If you don’t mind making this small adjustment, these batteries are a solid choice. I would have given them five stars if the leads were properly configured out of the box. Overall, they’re great value for the price! ## Features - [Battery size]: 10mm * 33mm * 95mm (T * W * L) - [Applicable equipment]:bluetooth speaker, dash cam, keyboard and mouse, Wi-Fi enabled smart home systems, PDA and digital cameras, GPS, monitoring units, notebook computers, e-books, telematics, tracking devices, sleep management equipment, blood oxygen tracking equipment, pulse monitors. - [Features]: Lithium-ion battery nominal voltage 3.7V, fully charged 3.7V, capacity 80mAh.
