## Description

EEMB Lithium Polymer Battery 3.7v 1800mAh 103450 Rechargeable Lipo Battery with JST Connector - Check the Polarity of Equipment and Connector Before Purchase

Review: 監視カメラの電源として利用しています。 充放電コントロールモジュールを使って、日中は太陽光パネルで充電し、その電力で監視カメラを動かしています。小型でかつ十分な容量があるため、この電池自体を充電することもなく、連続して運用できています。４箇所のハンダ付けとケースに格納するだけの簡単な作業で作成できたため、非常に満足しています。 欲を言えば、取り付けられているターミナルコネクタと対になるコネクタが付属していればと思います。
Review: The product was packaged very well, but the battery only charges to about 80% (4.0V instead of 4.2V). I discharged it fully (about 3.5V as the BMS/safety mechanism kicks in) and then recharged it, but I still can't get above 4.0V. I can't return it because I had to solder a different connector before I could use it. I left 2 stars instead of 1 because the battery safety mechanism seems to work and because packaging was decent.

*by J***L on 21 August 2025*

The battery works fine and the polarity is correct, as it seems some others have noted a polarity problem. The plug on this size battery does not appear to be standardized so my light would not accept it. So I had to cut the leads on the old plug and solder them to the new battery. It then works and fits fine. To be fair, it has a big warning on the description to check the shape and size of the plug you want. But I could not find another battery with a proper connector. So, if you don't do much soldering, be sure the plug will fit your project.
