近幾年，無(wu)人機(ji)航拍已經慢(man)慢(man)走進(jin)大(da)眾的(de)(de)視(shi)野(ye)，它(ta)非常(chang)規的(de)(de)拍攝(she)視(shi)角(jiao)、方(fang)便的(de)(de)操作、簡單的(de)(de)結構(gou)，贏(ying)得(de)了無(wu)數影(ying)像創作機(ji)構(gou)的(de)(de)芳心，甚至已進(jin)入普(pu)通百(bai)姓家。

目(mu)前主流的(de)(de)航拍無(wu)人(ren)機為(wei)(wei)多(duo)旋翼機、直機和固(gu)定(ding)翼，它們(men)的(de)(de)結構決定(ding)了(le)(le)能(neng)長時(shi)間(jian)飛(fei)(fei)(fei)行(xing)的(de)(de)是固(gu)定(ding)翼，但固(gu)定(ding)翼起(qi)飛(fei)(fei)(fei)和降(jiang)落要求高(gao)，在(zai)飛(fei)(fei)(fei)行(xing)中(zhong)不能(neng)懸停(ting)等因素往往只能(neng)用(yong)(yong)在(zai)測繪等對(dui)影像質量要求不高(gao)行(xing)業。而(er)多(duo)旋翼機、直機雖然(ran)飛(fei)(fei)(fei)行(xing)時(shi)間(jian)短，但可在(zai)復雜地型(xing)起(qi)降(jiang)，飛(fei)(fei)(fei)行(xing)平穩，可以懸停(ting)，抗風(feng)能(neng)力(li)好，操(cao)作(zuo)(zuo)易上手，是目(mu)前在(zai)影像創作(zuo)(zuo)上應(ying)用(yong)(yong)最多(duo)的(de)(de)機型(xing)。這兩種機型(xing)在(zai)動(dong)(dong)力(li)能(neng)源上以使(shi)用(yong)(yong)電(dian)(dian)(dian)池為(wei)(wei)主，直機還可以用(yong)(yong)油(you)動(dong)(dong)發動(dong)(dong)機提(ti)供(gong)動(dong)(dong)力(li)，但油(you)動(dong)(dong)產生的(de)(de)機械(xie)震動(dong)(dong)和更(geng)大(da)的(de)(de)飛(fei)(fei)(fei)行(xing)風(feng)險大(da)大(da)的(de)(de)降(jiang)低了(le)(le)其(qi)使(shi)用(yong)(yong)率。從而(er)電(dian)(dian)(dian)池的(de)(de)使(shi)用(yong)(yong)越(yue)來越(yue)在(zai)無(wu)人(ren)航拍中(zhong)普及開(kai)來，一(yi)(yi)個團(tuan)隊配備的(de)(de)各種電(dian)(dian)(dian)池少則十(shi)幾(ji)塊，多(duo)則幾(ji)十(shi)塊，它們(men)孜孜不倦(juan)地為(wei)(wei)電(dian)(dian)(dian)機、電(dian)(dian)(dian)調(diao)、飛(fei)(fei)(fei)控(kong)、OSD、圖傳(chuan)、接收機、遙(yao)控(kong)器(qi)(qi)、監視(shi)器(qi)(qi)等飛(fei)(fei)(fei)行(xing)器(qi)(qi)的(de)(de)各個用(yong)(yong)電(dian)(dian)(dian)部(bu)件提(ti)供(gong)電(dian)(dian)(dian)力(li)保(bao)障。為(wei)(wei)了(le)(le)更(geng)好的(de)(de)、更(geng)安全的(de)(de)飛(fei)(fei)(fei)行(xing)，就要去了(le)(le)解電(dian)(dian)(dian)池的(de)(de)參數、使(shi)用(yong)(yong)、保(bao)養、充放電(dian)(dian)(dian)等，這樣(yang)才能(neng)保(bao)障每次航拍任務的(de)(de)順利進(jin)行(xing)。下(xia)面就跟格氏一(yi)(yi)起(qi)了(le)(le)解一(yi)(yi)下(xia)在(zai)航拍中(zhong)默默奉獻的(de)(de)電(dian)(dian)(dian)池。

現在航(hang)拍上用的(de)鋰(li)(li)電(dian)池(chi)(chi)的(de)全稱(cheng)(cheng)為”“（Li-polymer,又稱(cheng)(cheng)高(gao)分(fen)子(zi)鋰(li)(li)電(dian)池(chi)(chi)），一(yi)(yi)般簡(jian)稱(cheng)(cheng)為鋰(li)(li)電(dian)。鋰(li)(li)聚合(he)(he)物(wu)電(dian)池(chi)(chi)具(ju)有能量密度高(gao)、更(geng)小型化、超(chao)薄化、輕量化，以及高(gao)安(an)全性和低成本等多種明顯優勢，是一(yi)(yi)種新型電(dian)池(chi)(chi)。在形(xing)狀上，鋰(li)(li)聚合(he)(he)物(wu)電(dian)池(chi)(chi)具(ju)有超(chao)薄化特征(zheng)，可(ke)以配合(he)(he)各種產品的(de)需要，制作成任何形(xing)狀與(yu)容量的(de)電(dian)池(chi)(chi)，外(wai)包裝為鋁塑包裝，有別于液態鋰(li)(li)電(dian)的(de)金屬(shu)外(wai)殼，內(nei)部質量隱(yin)患可(ke)立即通過外(wai)包裝變(bian)形(xing)而顯示出來，比如鼓(gu)脹。

下面就從電池的基本參數開始了解，以一塊22.2V10000mah航拍動力電池為例說明，它是由(you)6片額定電(dian)壓為3.7V、容量(liang)10000mah鋰電(dian)芯串聯(lian)而成，即常說的(de)(de)6S1P也有6S2P的(de)(de)電(dian)池，是由(you)12片5000mah的(de)(de)電(dian)池并聯(lian)加串聯(lian)組成的(de)(de)。這里要(yao)(yao)(yao)說明一(yi)點(dian)的(de)(de)是，6S1P要(yao)(yao)(yao)比6S2P安全系(xi)數要(yao)(yao)(yao)高，因為1P要(yao)(yao)(yao)比2P的(de)(de)結(jie)構(gou)簡單一(yi)倍，當然1P價格也要(yao)(yao)(yao)更高。

航模用鋰(li)電(dian)(dian)(dian)(dian)中，單片電(dian)(dian)(dian)(dian)芯(xin)電(dian)(dian)(dian)(dian)壓3.7V是(shi)額定(ding)電(dian)(dian)(dian)(dian)壓，是(shi)從(cong)平(ping)均工作電(dian)(dian)(dian)(dian)壓獲(huo)得。單片鋰(li)電(dian)(dian)(dian)(dian)芯(xin)的(de)實(shi)際(ji)電(dian)(dian)(dian)(dian)壓為(wei)2.75~4.2V,鋰(li)電(dian)(dian)(dian)(dian)上標(biao)的(de)電(dian)(dian)(dian)(dian)容(rong)量是(shi)4.2V放電(dian)(dian)(dian)(dian)至2.75V所獲(huo)得的(de)電(dian)(dian)(dian)(dian)量。鋰(li)電(dian)(dian)(dian)(dian)必須保持(chi)在2.75~4.2V這(zhe)(zhe)個電(dian)(dian)(dian)(dian)壓范圍內(nei)使(shi)用。如(ru)電(dian)(dian)(dian)(dian)壓低(di)于(yu)2.75V則屬(shu)于(yu)過度(du)放電(dian)(dian)(dian)(dian)，鋰(li)電(dian)(dian)(dian)(dian)會(hui)(hui)(hui)(hui)膨(peng)(peng)脹(zhang)，內(nei)部的(de)化(hua)學液體(ti)會(hui)(hui)(hui)(hui)結晶，這(zhe)(zhe)些結晶有可能會(hui)(hui)(hui)(hui)刺(ci)穿內(nei)部結構(gou)層造成(cheng)短路，甚至會(hui)(hui)(hui)(hui)讓(rang)鋰(li)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓變(bian)為(wei)零。充(chong)(chong)電(dian)(dian)(dian)(dian)時單片電(dian)(dian)(dian)(dian)壓高于(yu)4.2V屬(shu)于(yu)過度(du)充(chong)(chong)電(dian)(dian)(dian)(dian)，內(nei)部化(hua)學反應過于(yu)激烈(lie)，鋰(li)電(dian)(dian)(dian)(dian)會(hui)(hui)(hui)(hui)鼓氣膨(peng)(peng)脹(zhang)，若繼續充(chong)(chong)電(dian)(dian)(dian)(dian)會(hui)(hui)(hui)(hui)膨(peng)(peng)脹(zhang)、燃燒(shao)。所以一定(ding)要用符合(he)安全標(biao)準的(de)正規充(chong)(chong)電(dian)(dian)(dian)(dian)器對電(dian)(dian)(dian)(dian)池(chi)進(jin)行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)，同時嚴禁對充(chong)(chong)電(dian)(dian)(dian)(dian)器進(jin)行(xing)私自改裝，這(zhe)(zhe)可能會(hui)(hui)(hui)(hui)造成(cheng)很嚴重的(de)后果！

還要提示一點，切記：不能將航拍動力電池單片電芯電(dian)壓(ya)(ya)用到2.75V,此(ci)時(shi)電(dian)池已不(bu)能提供給飛(fei)機(ji)有效電(dian)力進行(xing)(xing)飛(fei)行(xing)(xing)，為(wei)了(le)安全(quan)飛(fei)行(xing)(xing)，可將單片(pian)報警電(dian)壓(ya)(ya)設為(wei)3.6V,如(ru)達到這個(ge)電(dian)壓(ya)(ya)，或接近此(ci)電(dian)壓(ya)(ya)，飛(fei)手就要馬執行(xing)(xing)返航或降落動作，盡可能避(bi)免因電(dian)池電(dian)壓(ya)(ya)不(bu)足(zu)導(dao)致炸機(ji)。

在電(dian)池的(de)使用上要堅持六個“不(bu)(bu)(bu)”，即(ji)不(bu)(bu)(bu)過充、不(bu)(bu)(bu)過放、不(bu)(bu)(bu)滿電(dian)保存、不(bu)(bu)(bu)損壞外皮、不(bu)(bu)(bu)短路、不(bu)(bu)(bu)著(zhu)涼正確(que)的(de)使用方法是延長

目前，航模鋰電池的品牌和(he)種類(lei)很多(duo)，要根據自(zi)己航模的用電(dian)需要去選擇相(xiang)匹配的電(dian)池，這樣才(cai)能(neng)(neng)(neng)保障各用電(dian)元(yuan)件(jian)的順(shun)利(li)運作。不(bu)要買一些便宜的三無電(dian)池，也不(bu)要去買電(dian)芯自(zi)己做電(dian)池，更(geng)(geng)不(bu)要去改裝電(dian)池。如果電(dian)池鼓包(bao)、破(po)皮、充不(bu)滿電(dian)等問(wen)題，請(qing)停止(zhi)使用。電(dian)池雖(sui)然是消耗品，但它給(gei)飛行默默提(ti)供著能(neng)(neng)(neng)源，我們要花時間(jian)的去重視(shi)它、了解它、愛護(hu)它，才(cai)能(neng)(neng)(neng)更(geng)(geng)好(hao)、更(geng)(geng)安全的為我們每一次航拍(pai)飛行任務服務。
