NiMH原來咁重, 迅間輸出又唔夠Li大A, 又唔夠Li大Voltage. 唔怪得唔夠爆.

Charging rate 幾多C, 代表最大可以用幾大A去charge.
e.g. 5000mAh 用4C charge, = 5000/1000Ah x 4 = 20A
即係5000mAh電, 如果用5A去charge要1hr, 20A去charge, 就15mins滿.

但一般LiPo電只建議一般時間只用1C去charge.

TT01要改裝先用到LiPo , 剪鬼曬D骨位!!

其實都係因為架X-ray有分安裝鋰電/MH電, 安鋰電佢要移條皮帶同頭尾大牙位, 好似好大分別咁.所以想問.

但係 Lipo 個 size 會似個方盒多少少
Nimh 個邊就圓圓地
今晚俾你試下你架車岩唔岩裝
我都新買左舊 Lipo電

The LiPo Paradox
This term was coined in airplane circles when it was discovered that a 1000mAh lipo pack would actually give longer flight times than a 1000mAh NiMH pack. You would think a mAh is a mAh, and that the battery chemistry doesn't matter, but it actually does! The reason why is two-fold. Speed controls work by sending very short pulses of full power to the motor. When one battery has a lower internal resistance than another, it maintains a higher voltage during the speed control’s pulses, and the actual throttle level required to maintain the same speed is lower. In addition, LiPos have a much higher surface charge due to their different chemistry, and can regenerate that charge faster than NiMH cells after each pulse. So again, the observed effect is a lower throttle level to achieve the same speed/power with a NiMH pack, which allows the LiPo pack to run significantly longer than its rated capacity would suggest. It's strange but true!
原來相同mAh, LiPO都耐力D.

Any more left for sale?
又想問LiPo同NiMH 各自幾重呢?
似乎佢個size都同NiMH有分別.
