現在fpv上(shang)使用的都(dou)是鋰電池，而(er)且在fpv競(jing)速比(bi)賽中很多飛手都(dou)采用3s/4s的電池。

所謂3s就是由3片鋰電芯串聯而成(3S1P)，即每片電芯的電壓為3.7V。單片鋰電芯的實際電壓為2.75~4.2V，鋰電上標的電容量是4.2V放電至2.75V所獲得的電量。fpv鋰電池必須保持在2.75~4.2V這個(ge)電(dian)(dian)(dian)壓范圍(wei)內使用。如電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓低于(yu)(yu)2.75V則屬于(yu)(yu)過(guo)(guo)度放(fang)(fang)電(dian)(dian)(dian)，鋰(li)電(dian)(dian)(dian)會(hui)膨(peng)(peng)(peng)脹(zhang)，內部的化(hua)學液(ye)體(ti)會(hui)結(jie)晶(jing)(jing)，這些(xie)結(jie)晶(jing)(jing)有可能會(hui)刺穿內部結(jie)構層造成短路，甚至會(hui)讓鋰(li)電(dian)(dian)(dian)電(dian)(dian)(dian)壓變為零。遙(yao)控航模鋰(li)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓高于(yu)(yu)4.2V屬于(yu)(yu)過(guo)(guo)度充(chong)電(dian)(dian)(dian)，內部化(hua)學反(fan)應過(guo)(guo)于(yu)(yu)激烈，鋰(li)電(dian)(dian)(dian)會(hui)鼓(gu)氣膨(peng)(peng)(peng)脹(zhang)，若繼續充(chong)電(dian)(dian)(dian)會(hui)膨(peng)(peng)(peng)脹(zhang)、燃燒。無論(lun)是過(guo)(guo)放(fang)(fang)還是過(guo)(guo)充(chong)均會(hui)對遙(yao)控航模鋰(li)電(dian)(dian)(dian)池(chi)產生很(hen)大的傷害。

由于用于fpv的電池很多時候都是暴力飛行，所以關于fpv電池的使用和維護必須要(yao)注意技巧。

1、充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)不得超(chao)過規定的限制(zhi)電(dian)(dian)(dian)壓(ya)(ya)（單片4.2V），4.25V為每只節(jie)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)的最(zui)高極限。充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)不宜過大（比如3s1500MAH的TATTU品牌電(dian)(dian)(dian)池一般用充電(dian)(dian)(dian)器設(she)定1.5a-2a充電(dian)(dian)(dian)）

2、正確連接電池的正負極(ji)，若正負極(ji)接反(fan)，將無法對(dui)電池進(jin)行充電。反(fan)向充電會使電池受到破壞，甚至導致發熱、泄漏、起火。

3、過放(fang)(fang)電(dian)會導致(zhi)電(dian)池損壞，放(fang)(fang)電(dian)時不(bu)得使單體電(dian)池的電(dian)壓低于(yu)3.6V（單片到3.8v的時候(hou)差不(bu)多飛機可以開始進行(xing)降落了）.

4、電(dian)(dian)池(chi)應放置在陰涼的環(huan)境下貯(zhu)存，長期存放電(dian)(dian)池(chi)時（超過(guo)3個月(yue)），建議置于溫度為10-25°C且低(di)溫度無腐蝕(shi)性氣(qi)體的環(huan)境中(zhong)。電(dian)(dian)池(chi)在長期貯(zhu)存過(guo)程(cheng)中(zhong)每3個月(yue)充放電(dian)(dian)一(yi)次以保持電(dian)(dian)池(chi)活性，并保證每個電(dian)(dian)芯電(dian)(dian)壓在3.7～3.9V范圍內！

5、再好(hao)的(de)電池也(ye)得(de)要配個好(hao)充(chong)電器(qi)，幾十元的(de)雜牌充(chong)電器(qi)不靠譜.

6、飛FPV一定要選用品(pin)牌(pai)電池，不用雜牌(pai)電池，單片電壓相(xiang)差大

7、熱天飛(fei)的時候(hou)(hou)盡量選擇日出前或(huo)者太陽下山的時候(hou)(hou)，溫(wen)度沒那么高，電(dian)池、電(dian)調注意散熱，能外掛在飛(fei)機(ji)(ji)外面(mian)(mian)盡量放飛(fei)機(ji)(ji)外面(mian)(mian)給它散熱.
