## Description

desertcart.co.jp: EEMB Lithium Polymer Battery 3.7V 1800mAh 103450 Lipo Rechargeable Battery Pack with JST Connector - Check the polarity of your device and connector before purchase : Electronics

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: Bluetoothキーボードのバッテリーが駄目になってしまったので交換用に購入。コネクタは不要だったので切断してはんだ付けしました。耐久性はまだ不明ですが今のところ問題なく動いています。薄く容量もそこそこあるのでいろんな場所に使えそうです
