NIU Scooter Extra Range and Performance Dual Battery Accessory

Description

Dual Battery Connection Set-up

With this accessory you can use two batteries simultaneously as long as they are the same voltage. The accessory has to be added into the circuit of the existing original battery and controller. If you the dual battery setup with our larger capacity motherboards this will increase the power of your scooter since there is now more input from the batteries and the motherboards are able to pass on more output to the motor. This accessory is great if you want to increase the performance and the range of your scooter with a cost efficient way.

Features

• If paired with our motherboards you can increase the performance of your scooter as you now have the capacity of two batteries allowing you to increase acceleration and top speed. If you do not have our motherboards it will only increase the range without any performance speed up.
• Use both batteries simultaneously allows for  increasing range by x2
• Ability to charge both batteries through the scooter port.
• The diode will regulates differences in battery level between the two batteries meaning that if one battery were to be lower than the diode will use them accordingly.
• Prevent you from having to swap batteries

Common Questions:

What is the purpose of the diode?

• Without the diode if there are any differences in battery level because one battery isn’t charged properly or whether the battery life of the batteries are not the same the diode will help regulate these differences.
• If one were to use two batteries without the diode it would result in the error of that the scooter is charging because the circuit is not parallel, battery A will start charging battery B resulting in a charging error.
