用途
- 測量 1S ~ 8S 的鋰電池電壓
- 若電壓太低,蜂鳴器會發出聲響警告,紅色 LED 也會亮起
-
使用方法
- 插於電池的 平衡充接頭 上
- 測電器負極插入平衡充接頭的負極

- 電池使用前就必須先插上測電器
- 插上後,蜂鳴器會發出 BB 兩聲,面板上也會顯示電壓,沒響代表失敗,可能是腳位插錯
- 面版依序顯示:總電壓 → 第一電芯電壓 → 第二電芯電壓 → …

規格
- 電壓
- 單位為 (伏特)
- 電壓越高,轉速越快,但是太高可能導致馬達燒壞
- 正常的鋰聚電池電壓不得低於 且不得高於
- 過放:電池電壓過低
- 容量
- 電力的總量,單位為 (毫安培小時)或 (安培小時),數字越大電量越多,
- 放電係數
- 單位為 (1 / 小時)
- 充放電時,電流大小與電池容量的比率
- 將放電係數乘上容量可以得到最大持續放電電流
- 實際運用時,仍需注意馬達的極限電流,超過馬達的電流值是不會被使用的
放電係數
放電係數亦稱為充放電率(C-rate),舉例來說,當一容量為 800 mAhr 的電池,其放電電流為 100 mA ,則它的充電系數為 0.125 C (100 mA / 800 mAh),亦即需要 8 小時才可以充放電完畢

電池保養方式
- 避免直接日曬、潮濕、遠離高溫,選擇乾燥、陰涼處擺放
- 切勿充飽電存放超過 48 小時,充飽電的鋰聚電池因為內部化學反應相當活絡,所以當充飽電存放太久,鋰聚電池會自我老化,降低放電能力。最好的情況是保持鋰聚電池在 3.5~3.8V(單芯)時存放
- 一般而言,長時間不使用時,應將電池充至 70~80%進行存放。防止長時間的自然放電後,電壓低於 2.0 伏特,導致電池失效而不能使用

經常把鋰離子電池電量耗盡,比經常充放電的使用壽命至少縮短一半以上
- 嚴禁過放,使用中因為有負載,電壓會比靜止測量來的低,所以當負載停止後測量電壓是 2.8 以下時,那可能你的使用過程中已經造成了電池過放的現象,最保險的使用方式,是使用完後測量的電壓是 3.5V 以上
