自制一個簡單實用的鋰電池充電器改變(bian)圖中(zhong)4歐(ou)的電(dian)(dian)(dian)(dian)阻(zu)可以改變(bian)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，D1是電(dian)(dian)(dian)(dian)源(yuan)指示，D2是充(chong)電(dian)(dian)(dian)(dian)指示兼限流。調試時6.8K電(dian)(dian)(dian)(dian)阻(zu)用(yong)一10K微調電(dian)(dian)(dian)(dian)阻(zu)代換，用(yong)數字表監視電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓到4.2V時，調10K微調電(dian)(dian)(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)阻用一10K微調電(dian)阻代換，用數字表監視電(dian)池電(dian)壓到4.2V時，調10K微調電(dian)阻到6.8K即可。
