超小型電池

如果你有接觸過拍攝工作,你就會明白電池對戶外工作的重要性有多大。不管要用到多少,電池的數量一定要比預期更多,否則只要不夠電池,你的拍攝工作隨時就因此而受阻、甚至中斷。
早前敝公司收到一箱貨品,我在看收貨單時就只知道是電池,沒有多加理會就放在座位旁邊。本來只想著過一兩天就把貨品轉寄出去,連驗貨也省下,結果因為某些原因,還是把紙箱開了,開箱後卻驚喜不斷!
雖然看來沒有甚麼特別,但它的體積和規格,卻實實在在的把我嚇倒了:
Lithium Polymer / 14.8V / 1800mAh / 54x36x35mm
如果看不明白的話,給你想像一下它的體積:如果要和大小相近的電池比較,我就要說它比9V電池大一點點;而9V充電池的電容量大約是285mAh,就當它是兩枚,電容量也只是570mAh而已,仍比那枚電池的電容量相差三倍有多!
想想看那個14.8V電池可以用來做甚麼?不少聲稱是支援12V的產品,其實還是有一點寬容度的 – 乾電池在使用其間,電壓都一直在改變。Monitor、機頂燈、還有不少的攝影附件,這枚電池都能夠滿足它們的需要;配合高電容量、輕巧的體積和重量,隨時能夠一枚用足整天,要多帶幾枚也不會感到累贅!
提提你,目前的電影攝影行業,仍然主力使用汽車電池(Lead Acid),體積如磚頭般大,背負它四處走一定會令你大喊疲倦。就算敝公司已經全面轉用鋰聚合物(Lithium Polymer)電池,卻還是未有這個超小體積版本可供租出。
可是,不要以為體積小就會便宜,一枚這樣的電池大約售數百美元,還未算上度身訂制的充電器費用呢!所以就算我很想買幾枚自用,最後還是因為價錢太貴而作罷。還好Lithium Polymer電池的耐用度比Lead Acid高出很多,總計成本之下,長遠而言還是蠻化算的。
