first of all sorry for confusing some people , I come from the other half of world

current = amperage draw "A" , maybe that confused you guys

power capacity of battery is in mAh , the C is simply a factor you multiply by the mAh to get maximum amperage provided by the battery , they call it "capacity" for no clear reason ,

40 amp is the amperage draw on the motor side not the battery

and still higher voltage means higher amperage ! 40 on 2s is probably 60 on 3s

static or constant resistance, it will behave the same in different voltages !! and will give different amperage ,
