用電趨向

I think a charge up NiMh battery will be around 1.4-1.5V so that 6x is around 9V max.
For NiZn, 4x1.9 is around 7.6V and still a lot less than 6xNiMh.
So I recommend you not try to use 6xNiMh or you will push it to the limit too soon.

LiFe電嘅好處係輕同易揾差機，但容量較少，可能只玩到五分鐘，用無刷可能耐啲！
NiZn就唔洗改車，Volt數高所以超快，但難揾差機，就算用一般LiPo / LiFe mode差有可能好快打柴！
