Thank you for buying one of your Alien Rides Range Extender! Before you get riding please read this short manual carefully.

UPDATE: NOV 2022.  All of our range extenders now ship with a Smart BMS with Bluetooth voltmeter, auto cell balancing, and live voltage of each cell group.  The smart BMS extends the life of your battery even after hundreds and hundreds of charges.

Before First Ride:

Secure the bag to both the stem and the handlebar with the integrated velcro straps. Make sure that it is rigid even during violent vibrations.

After Riding:

Check the bag and its straps to make sure it is safely secured. Always charge the scooter with the range extender plugged in so that the voltages between both the external battery and the internal battery are within one volt of each other. To prevent electrical errors, never charge the range extender separate from the scooter.
