"Formerly posted by SeyKai: I might not be totally correct but I was refering to ampere hour . Higher ampere will have more power to go further. thanks "
I'm sorry but I can't stop myself getting this clarified since you seemed totally confused...
Amphere hour has nothing to do with power.
Amphere hour is an indicator of capacity of your battery, it's not even the full picture though.
Amphere does NOT = Power
Amphere x Voltage does, this is basic physics.
Higher Amphere somewhat = Higher Torque, given the exact same system, by which I mean same motor, same battery, same controller...
However you can't decide how much Amphere your battery can supply, although many of them have a rated Amphere output.
You can however decide the Voltage of your system, but adding more battery cells and replacing a controller of a higher rating. This might make your scooter go faster. This will appear in ways such as accelerating faster, crusing at higher speed, etc.
But remember a key factor which is the motor, which is designed for the current power rating of the system.
By increasing the power rating of the system, you put more stress to the motor, more particularly, higher surge current during starting/accelerating and higher RPM during cruising.
While not knowing the winding specs of the motor, higher current might overheat the coils and melt the enamelded wires, which potentially lead to shorting of coils or in the other word, spoiled motor. In a less fxxked-up senario, your scooter will just keep running but become damn hot, and slow since all the extra energy your system output becomes heating power.
Higher RPM might have lesser impact but it obviously put more stress to the bearing, which has a designed running RPM.
At a higher level, your axles, the board itself, even the tires are designed as part of the system, with the designed power of XYZ. Increasing the power put over rated stress to all these parts, so don't be surprised if you see them failing faster.
Trying to increase the mileage however shouldn't do you any bad, you should be able to do it by replacing the battery pack with a higher capacity, but, of the same Voltage.
