自制一個簡單實用的鋰電池充電器改變(bian)(bian)圖中4歐的電(dian)(dian)(dian)阻(zu)可(ke)以改變(bian)(bian)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，D1是電(dian)(dian)(dian)源指示，D2是充(chong)電(dian)(dian)(dian)指示兼限(xian)流。調(diao)試時(shi)6.8K電(dian)(dian)(dian)阻(zu)用一(yi)10K微調(diao)電(dian)(dian)(dian)阻(zu)代換，用數字表監視電(dian)(dian)(dian)池電(dian)(dian)(dian)壓到4.2V時(shi)，調(diao)10K微調(diao)電(dian)(dian)(dian)阻(zu)到6.8K即可(ke)。

 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(diao)試時(shi)6.8K電(dian)(dian)阻用一10K微(wei)(wei)調(diao)電(dian)(dian)阻代換(huan)，用數(shu)字(zi)表監視電(dian)(dian)池電(dian)(dian)壓到4.2V時(shi)，調(diao)10K微(wei)(wei)調(diao)電(dian)(dian)阻到6.8K即可。
