>但我試過 gp 的簡電好似又唔係.... 仲慢左...
有3排 GP, 1600, 2000, 2100mAh
用響 550EX, 2X00 比 1600 回電快好多, 亦襟"淝"好多

panasonic NiMH 2100
呢隻小弟用緊，感覺幾快，但係應該可以再快ｄ |

勁量新出的Lithium，又輕又快，不過都幾貴下，要成五十蚊兩粒(AA size) |

我都係用 panasonic NiMH 2100 + 佢既 BQ-395 叉機，
好好用，次次叉得好飽，
去日本個 TOUR 影超過 25 筒相(當然不是張張那隻啦)，
都仲回電好快，勁！ |

有冇想過, 閃燈回電快, 係好易燒支閃燈?
|

唔怕掛.....部份閃光有cooler
而且無cooler (e.g. metz 60CT)
一樣無事...重點係,十年唔用一次燈.... |

咁都唔貼題? 只係一味要求回電快, 燒燈既可能性亦會加大, photosharp_kai, 你知唔知閃燈電器特性又係乜? 相機內置閃燈到極亦只係 GN20, 而外閃就一般GN24至60, 其充電時的峰值電流可以是5A以上, 只是囉 一個相機及電池的PDF出來, 根本就是誤導! 比浪費版面更無知及無恥! photosharp_kai, 希望你的思想不是那麼簡單吧, 別人問A你就只是可答A, 好一個TOO SIMPLE, 世界不是非黑即白, 問題本身可能已經存在了更多問題, 如我在問題上作BRAIN STORMING就是浪費版面, 好明顯就是閣下根本沒有研究問題就答! 別人真係燒燈你又要負咩責任?! 睇睇啦, 燒閃燈係吹水還是講真, 用腦想一想吧. http://www.burren.cx/photo/flash_power.htmlhttp://www.sederquist.com/claflash.html |

啊啊啊~~ 唔駛火氣咁重... 我之前上開的forum 就係有太多arguing 所以轉左黎這邊, 大家討論下...
我又冇想過會燒燈... 我知燈可以燒, 但我以為燈上的閃燈預備燈著後, 就表示可安全閃燈... 那它沒有保險嗎??? 在閃燈燒前, 用手可不可以感覺得到它很熱呢?? 我用 canon 的 550...
似乎大家都話 rechargable 的電回氣快d, 真開心~~~ (我通常都係在一個位連影兩三張, 跟著就找另一個景位, 所以中間都有五分鐘左右的時間.. 再加上如果不是影人我很少用燈...所以燒燈的機會應該不高吧...) |

power for flash can be very dangerous. I have made my own power supply with 4 size C Nicd recharge batteries for my Canon 300TL flash and Metz Mz40 many years ago. As both flash does not have any original external power connections, I DIY by using large power clips that commonly found in Physic Labs. that external power can recycle both flash within 2s. It works very fine at the very beginning.
Once, those clips burns when I was using with my 300T in a wedding. very embarrassing. I measure that current is as high as 6A when the flash is charging. I have to replace it with a very formal power collections.
My Metz 40mz burns after a period of 4 to 6 months. I don"t know if it is related to my DIY power supply. I finally get a G15 grips for my metz and I am still using that power supply for my cannon flash for some time without serious problem
However, seldom use it recently, as we get 2300mah AA batteries now. Just a little bit lower capacity to the C batteries I used in old day. Seldom need more than 3 sets of 4 2300mah AA batteries for a wedding day that already support more than 30 rolls of falsh photography in AE/TTL mode normally.
by the way, Nicd charge quicker than NiMH on my flashes.

閃燈可以短時間回電好正架,
試想一下拍人像時連拍連閃...嚓~嚓~嚓~嚓~嚓~ 的樂趣.

It burn suddenly, you did not know it.
And besides the 閃燈, the capacitors are not easily to be burn as well.

我"估"如果可以燒得，都應該係閃燈有問題，因為呢d野應該一早計好，電壓就以經有，電流都應該無可能無限大啦....呢d係吾係中學學過呢？？我都吾記得...... |

可以想像到場面真係好核突, 有無嚇親對新人?
DIY 就有呢 D 存在危險

luckily, I discover it very quickly, very few people notice it. and I always get backup flash, cmaera and lenses in such ocassions.

One matter missing in yours saying, the internal resistance of batteries.
Internal resistance of recharable batteries are very difference to normal batteries, Alkaline batteries, Lithium batteries. A size C cell react very differently to an AA batteries.
The two flashes I used are not designed to use with size C recharable cells originally.
