把動力鋰電池組串聯和并聯起來使用，這聽起來好象很簡單，但是，遵循一些簡單的規則，就可以避免不必要的問題。鋰電池組包含兩部分：鋰電池和鋰電池保護板線路。

并(bing)聯(lian)(lian)(lian)為(wei)了得到更(geng)多的(de)(de)(de)電(dian)(dian)(dian)(dian)量(liang)，可(ke)以(yi)把兩(liang)個(ge)或者更(geng)多個(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)并(bing)聯(lian)(lian)(lian)起來。除了把電(dian)(dian)(dian)(dian)池(chi)(chi)并(bing)聯(lian)(lian)(lian)起來，另一(yi)個(ge)辦法是使(shi)用(yong)尺寸更(geng)大(da)(da)(da)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。由(you)(you)于受到可(ke)以(yi)選用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)限(xian)制，這個(ge)辦法并(bing)不適用(yong)于所(suo)有情況。此外(wai)，大(da)(da)(da)尺寸的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)也不適合(he)做成專用(yong)電(dian)(dian)(dian)(dian)池(chi)(chi)所(suo)需(xu)要的(de)(de)(de)外(wai)形規格(ge)。大(da)(da)(da)部分的(de)(de)(de)化(hua)學電(dian)(dian)(dian)(dian)池(chi)(chi)都可(ke)以(yi)并(bing)聯(lian)(lian)(lian)使(shi)用(yong)，而(er)鋰(li)離子電(dian)(dian)(dian)(dian)池(chi)(chi)最適合(he)并(bing)聯(lian)(lian)(lian)使(shi)用(yong)。由(you)(you)四節電(dian)(dian)(dian)(dian)池(chi)(chi)并(bing)聯(lian)(lian)(lian)而(er)成的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)組，電(dian)(dian)(dian)(dian)壓保(bao)持為(wei)3.6V，而(er)電(dian)(dian)(dian)(dian)流和運(yun)行(xing)時間則增大(da)(da)(da)到四倍(bei)。與電(dian)(dian)(dian)(dian)池(chi)(chi)串聯(lian)(lian)(lian)相比(bi)，在(zai)電(dian)(dian)(dian)(dian)池(chi)(chi)并(bing)聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)，高(gao)阻(zu)抗或“開路(lu)(lu)”電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)影響較小，但是，并(bing)聯(lian)(lian)(lian)電(dian)(dian)(dian)(dian)池(chi)(chi)組會(hui)減(jian)少負載能力，并(bing)縮短運(yun)行(xing)時間。這就(jiu)好比(bi)一(yi)個(ge)發動(dong)機只啟動(dong)了三個(ge)汽缸。電(dian)(dian)(dian)(dian)路(lu)(lu)短路(lu)(lu)所(suo)造成的(de)(de)(de)破壞會(hui)更(geng)大(da)(da)(da)，這是因(yin)為(wei)，在(zai)短路(lu)(lu)時，出現(xian)故障(zhang)的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)會(hui)迅速地耗(hao)盡其他(ta)電(dian)(dian)(dian)(dian)池(chi)(chi)里的(de)(de)(de)電(dian)(dian)(dian)(dian)量(liang)，并(bing)引起火災(zai).

使用串(chuan)并聯這(zhe)種連(lian)接方法時，在設(she)計上很靈活，可以(yi)用標準的電(dian)(dian)池尺寸達到所需要(yao)的額定電(dian)(dian)壓(ya)(ya)和電(dian)(dian)流(liu)。應(ying)當注意：總(zong)功率不會因為電(dian)(dian)池的不同(tong)連(lian)接方法而改變。功率等于電(dian)(dian)壓(ya)(ya)乘(cheng)電(dian)(dian)流(liu)。對鋰離子電(dian)(dian)池而言，串(chuan)并聯的連(lian)接方法很常見。

最常用的一種電池組是18650鋰離子電池（直徑為18mm，長度為650mm），它帶有保護電路即鋰電池保護板，鋰電池保護板能夠監視串聯在一起的每一節電池，因此，它的最大實際電壓為14.4V。這個鋰電池保護電路（即鋰電保護板）也可以用于監視串聯在一起的每一節電池的狀態。在把幾個電池串聯起來使用時，必須遵照下面的基本要求：保持電池的連接點的潔凈。把四節電池串聯起來使用時，共有八個連接點（電池到電池室的連接點，電池室到下一節電池的連接點）。每個連接點都存在一定的電阻，如果增加連接點，有可能會影響整個電池組的性能。不要混用電池，選擇性能一致的電池。當電池的電量不足時，更換所有的電池。在串聯使用時，要用同一種類型的電池。要注意電池的極性。如果有一節電池的極性裝反了，就會減少整串電池的電壓，而不是增加電壓。
