自制一個簡單實用的鋰電池充電器改(gai)變圖中4歐的電(dian)(dian)阻(zu)可以改(gai)變充電(dian)(dian)電(dian)(dian)流(liu)，D1是(shi)電(dian)(dian)源(yuan)指(zhi)示，D2是(shi)充電(dian)(dian)指(zhi)示兼限流(liu)。調試(shi)時6.8K電(dian)(dian)阻(zu)用(yong)一10K微調電(dian)(dian)阻(zu)代換，用(yong)數字表(biao)監視電(dian)(dian)池電(dian)(dian)壓到4.2V時，調10K微調電(dian)(dian)阻(zu)到6.8K即可。

 自制一個簡單實用的 
    改變圖中4歐的電阻可以改變充電電流，D1是電源指示，D2是充電指示兼限流。
    調試時6.8K電(dian)(dian)阻用一10K微調電(dian)(dian)阻代(dai)換，用數(shu)字(zi)表監視電(dian)(dian)池(chi)電(dian)(dian)壓到4.2V時，調10K微調電(dian)(dian)阻到6.8K即可。
