402780 3.7V Lipo Battery 950mAh 402780 Rechargeable Lithium Polymer Battery Pack with JST PH2.0mm Connector for Electronic Device

A direct replacement for the battery in my LTC MHM-001 wireless mouse. Exterior dimensions are accurate on the site.. The lead wire was shorter than on my original battery, but still long enough for my device.For others with the LTC mouse, nearly complete disassembly is required to access the battery compartment. It's all snap fit and expect to use a plastic pry bar (spudger) and a tiny Phillips screwdriver to replace the battery.No complaints thus far. External build quality seems good. I will update if my battery does not last. Only time will tell if the value is there.

Works great. Replaced original in a digital mirror.

Have a AquaticAV brand audio system on my hot tub that is only a few years old. The battery in the remote died and AquaticAV was no help in getting it replaced. Just wanted to sell me a complete new remote. I carefully opened up the remote and ordered a new battery. Some minor soldering and its back in operation again. A bonus is that the replacement battery is slightly larger capacity yet still fits inside the remote.

I had read about this being a concern some months ago, but completely forgot that I needed to worry about this. I was excited to connect it to a new Meshtastic device that arrived a couple of days ago. It immediately let all the smoke out of that $30 unit. I expect that the battery is still fine. The connector can only go in one way, but that doesn't mean that the wires were inserted with the polarity that your device is expecting. Double-check before you toast your device.

This high-capacity LiPo battery offers reliable performance for electronic projects. The 10000mAh capacity provides substantial runtime, while the integrated protection circuitry safeguards against overcharging, over-discharging, and short circuits. The JST PH2.0mm connector is well-secured and compatible with many common development boards and electronic devices.Build quality is solid - the cell is properly encased with good insulation, and the wire gauge is appropriate for the current rating. The voltage stability remains consistent throughout the discharge cycle, which is crucial for sensitive electronics. The battery arrives partially charged, allowing for immediate testing while still maintaining safe storage levels.The form factor is well-suited for many project enclosures, though you'll want to verify dimensional requirements as it's substantially sized. The connector pins are properly aligned and make positive contact, though adding a small dab of hot glue for strain relief is recommended for portable applications. Self-discharge rate is minimal during storage.One consideration is the charging time - it requires patience with standard charging rates to maintain cell longevity. While not the most compact 10000mAh option, the protection circuitry and build quality justify the size. For makers and electronics enthusiasts needing reliable portable power, this battery provides a good balance of capacity, safety features, and value.​​​​​​​​​​​​​​​​

Fine but needed to mod the control board for my use case.

When you buy a lipo battery you need to find a good seller that knows if these batteries have been sitting around for quit a while. Then they typically do not work they have been sitting to long and will not charge up.I chose a 160 instead of 150 mAH just to make sure it had enough power to fly my little heli. BUT the distributer has no idea how old there stuff is I have bought twice from them and the battery is junk I had to cut the plug so I could soder it to my heli and bad battery again I was being fair and giving the second chance but now I know not to buy from them. I had to cut the plug off so no sending back do not buy from this seller they do not care about there customer

Warning: The picture giving the dimensions for the 302530 3.7V Lipo Battery 150mAh version is wrong. It is actually about 10mm larger in length and width. Don't assume it will fit based on the picture.
