◆航拍獨愛電池

眾所周(zhou)知，市場上流通(tong)的(de)(de)(de)(de)航(hang)(hang)拍無(wu)人(ren)(ren)(ren)機(ji)基(ji)本上為(wei)多(duo)旋翼機(ji)、直機(ji)和固定(ding)翼。他們的(de)(de)(de)(de)結構(gou)直接(jie)影(ying)響著它們的(de)(de)(de)(de)功(gong)能，好比固定(ding)翼雖(sui)飛行(xing)時(shi)間(jian)(jian)長卻(que)多(duo)數(shu)用(yong)來測繪等對影(ying)像質量要求不(bu)(bu)高的(de)(de)(de)(de)行(xing)業，而多(duo)旋翼機(ji)、直機(ji)飛行(xing)時(shi)間(jian)(jian)短卻(que)倍受影(ying)像創作(zuo)者青睞。雖(sui)然直機(ji)可(ke)以油動(dong)發動(dong)機(ji)提供(gong)動(dong)力，但是油動(dong)產生的(de)(de)(de)(de)機(ji)械振動(dong)和更大的(de)(de)(de)(de)飛行(xing)風險讓(rang)不(bu)(bu)少人(ren)(ren)(ren)避(bi)而遠(yuan)之，從而電池(chi)在無(wu)人(ren)(ren)(ren)航(hang)(hang)拍中成(cheng)了無(wu)可(ke)爭議(yi)的(de)(de)(de)(de)寵兒。一次完整的(de)(de)(de)(de)航(hang)(hang)拍，耗(hao)時(shi)較久，且無(wu)人(ren)(ren)(ren)機(ji)的(de)(de)(de)(de)各個部(bu)件的(de)(de)(de)(de)電量總耗(hao)加(jia)起來，也是不(bu)(bu)容忽視的(de)(de)(de)(de)。因此選則符合(he)自己心愛的(de)(de)(de)(de)無(wu)人(ren)(ren)(ren)機(ji)的(de)(de)(de)(de)電池(chi)并且熟知電池(chi)的(de)(de)(de)(de)參數(shu)、保養、使用(yong)等問(wen)題尤為(wei)重要，只有做(zuo)好了充足的(de)(de)(de)(de)準備(bei)，才能保證航(hang)(hang)拍任務順利完成(cheng)，下面就讓(rang)我們一起來了解那(nei)個航(hang)(hang)拍鐘情的(de)(de)(de)(de)它。

◆它叫鋰聚合物電池

目前航拍市場使用的鋰電池全稱為“鋰聚合物電池”（Li-polymer，又稱高分子鋰電池），一般簡稱為鋰電。鋰聚合物電池具有能量密度高、更小型化、超薄化、輕量化，以及高安全性和低成本等多種明顯優勢，是一種新型電池。在形狀上，鋰聚合物電池具有超薄化特征，可以配合各種產品的需要，制作成任何形狀與容量的無人機電池，外包裝為鋁塑包裝，有別于液態鋰電的金屬外殼，內部質量隱患可立即通過外包裝變形而顯示出來，比如鼓脹
鋰電鼓脹

內部質量隱患，應做好防范及時(shi)處理

◆與它的相惜相知

從電池的(de)基本參數(shu)開始了解，以一塊(kuai)22.2V 10000mAh航(hang)拍動力(li)電池為例說(shuo)明(ming)，它是由6片額(e)定電壓為3.7V、容量(liang)10000mAh鋰電芯串聯而成(cheng)，即(ji)常說(shuo)的(de)6S1P。也(ye)有6S2P的(de)電池，是由12片5000mAh的(de)電池并(bing)聯加串聯組成(cheng)的(de)。這里要說(shuo)明(ming)一點(dian)的(de)是，6S1P要比6S2P安全(quan)系數(shu)要高，因為1P要比2P的(de)結(jie)構簡單一倍，當然1P價(jia)格也(ye)要更高

◆與它適合的節拍

航模用鋰電中，單片電芯電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)3.7 V是額定電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，是從平均工作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)獲得。單片鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)芯的(de)實際(ji)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)為2.75~4.2 V，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)上標的(de)電(dian)(dian)(dian)(dian)(dian)容量是4.2 V放電(dian)(dian)(dian)(dian)(dian)至2 .7 5 V所獲得的(de)電(dian)(dian)(dian)(dian)(dian)量。鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)必須保(bao)持在2.75~4.2V這個電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)范圍內(nei)使用(yong)。如電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)低于(yu)(yu)2.75V則屬于(yu)(yu)過(guo)(guo)度(du)放電(dian)(dian)(dian)(dian)(dian)，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)會(hui)膨(peng)脹，內(nei)部的(de)化學(xue)液(ye)體(ti)會(hui)結晶，這些結晶有(you)可(ke)能會(hui)刺穿(chuan)內(nei)部結構層造成短路，甚至會(hui)讓鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)變為零。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時單片電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)高于(yu)(yu)4.2V屬于(yu)(yu)過(guo)(guo)度(du)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，內(nei)部化學(xue)反應過(guo)(guo)于(yu)(yu)激烈，鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)會(hui)鼓氣膨(peng)脹，若繼續(xu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)會(hui)膨(peng)脹、燃燒。所以一(yi)定要用(yong)符合安全標準的(de)正規充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器對電(dian)(dian)(dian)(dian)(dian)池進行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，同時嚴禁對充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器進行私自改裝，這可(ke)能會(hui)造成很(hen)嚴重(zhong)的(de)后果！

◆深知它不愛炸機

鄭重提示一點，切(qie)記——不(bu)能(neng)(neng)將(jiang)航(hang)拍動力電(dian)(dian)池(chi)單片電(dian)(dian)芯(xin)電(dian)(dian)壓用到2.75V，此時(shi)無人(ren)機電(dian)(dian)池(chi)已(yi)不(bu)能(neng)(neng)提供給飛(fei)機有效電(dian)(dian)力進行(xing)(xing)(xing)飛(fei)行(xing)(xing)(xing)，為了安全飛(fei)行(xing)(xing)(xing)，可將(jiang)單片報警電(dian)(dian)壓設(she)為3.6V，如達到這個電(dian)(dian)壓，或接近此電(dian)(dian)壓，飛(fei)手(shou)就要馬上(shang)執(zhi)行(xing)(xing)(xing)返航(hang)或降落動作，做好(hao)安全防范措(cuo)施，盡可能(neng)(neng)避(bi)免因電(dian)(dian)池(chi)電(dian)(dian)壓不(bu)足導致(zhi)炸機。

◆用久見池芯

無(wu)人機鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)力是(shi)(shi)(shi)(shi)(shi)(shi)以倍(bei)數(shu)（C）來(lai)表示的(de)(de)(de)(de)，意(yi)思是(shi)(shi)(shi)(shi)(shi)(shi)說按照無(wu)人機電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)標(biao)稱容(rong)(rong)量最大可達到多大的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)。常見的(de)(de)(de)(de)航拍用電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)有(you)(you)15C、20C、25C或者更高(gao)C數(shu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。至(zhi)于C數(shu)，簡單(dan)地說，1C針對不同容(rong)(rong)量電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)(shi)(shi)(shi)(shi)(shi)不一樣的(de)(de)(de)(de)。1C是(shi)(shi)(shi)(shi)(shi)(shi)指無(wu)人機電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)用1C的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)率放電(dian)(dian)(dian)(dian)(dian)可以持續工(gong)作1小時(shi)。例：10000mAh容(rong)(rong)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)持續工(gong)作1小時(shi)，那(nei)么平均電(dian)(dian)(dian)(dian)(dian)流(liu)是(shi)(shi)(shi)(shi)(shi)(shi)10000mAh,即10A，10A即是(shi)(shi)(shi)(shi)(shi)(shi)這(zhe)個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)1C。再如電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)標(biao)有(you)(you)10000mAh 25C，那(nei)么最大放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)是(shi)(shi)(shi)(shi)(shi)(shi)10A×25=250A，如果是(shi)(shi)(shi)(shi)(shi)(shi)15C，那(nei)么最大放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)是(shi)(shi)(shi)(shi)(shi)(shi)10A×15=150A，從此可以看出飛(fei)機在進行(xing)(xing)大動態飛(fei)行(xing)(xing)的(de)(de)(de)(de)時(shi)候(hou)，C數(shu)越高(gao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)就(jiu)能(neng)(neng)根據動力消(xiao)耗的(de)(de)(de)(de)瞬間提供更多電(dian)(dian)(dian)(dian)(dian)流(liu)支(zhi)持，它的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)性(xing)能(neng)(neng)會更好(hao)，當然C數(shu)越高(gao)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)價位(wei)也(ye)會升高(gao)。這(zhe)里要(yao)注意(yi)的(de)(de)(de)(de)千(qian)萬(wan)不要(yao)超過(guo)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)C數(shu)進行(xing)(xing)放電(dian)(dian)(dian)(dian)(dian)，否則(ze)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)有(you)(you)可能(neng)(neng)會報廢或燃燒爆炸。
