Photo and product description
采用锂电专用充电管理4056的充电板,搭载双MOS自动极性转换电路,接电池不用分正负极。用于改造维修市售万用充电器,具有充电安全,截止比较准确,不过充等特点。
体积超小:20*12*4mm,还能放入USB插头里{需打磨插头外壳}。
电源输入电压:DC5V{分正负,反接必烧};
充电电流:600MA{更换电阻可改1A电流,需加强IC的散热};
电池端:不用分正负极;
充满电压:4.2V(误差1%,4.158-4.242之间);
充电红灯,充满蓝灯,自动转停不过充,保护电池。
与电池连接线要短而粗,避免内阻过大而充不满,测量终止电压要测电池端,在充电板指示灯转灯的那一瞬间为准确,转灯过后因电池性能不一,电压会缓慢下降,这时测量是不准确的。
