Dual Battery Connection Set-up

With this accessory you can connect two batteries as long as they are the same voltage into the scooter circuit. You can also charge both batteries from the scooter. 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.


When using both batteries you can not have a difference in battery level. You have to charge both and use both.

    Before the double connector (50)ah it wanted 10 procent to get 10 km, very easy to calculate and now 80 ah it took just 8 procent to get 9 km ! With only original 29ah it took 28% to get me 13 km! Total distance I don’t really know yet! I think the app needs more data to calculate, it took some time to see any difference when 50ah was installed! And overall it’s so much more fun!
