If you are having issues with low range or a completely non-functional scooter due to battery issues, you may need to replace the battery.
This guide shows how to Replace the internal battery/BMS for the following scooters:
Retail Specific
Rental Specific
Yours may still work and just not be listed.
Accessing the Battery
Removing the Pole
Remove the 4x Security Torx T25 screws or Hex Screws that hold the handlebar in place on the pole.
Remove the 4x Security Torx T30 screws or Hex screws that hold the pole to the base.
Accessing the Internals
If you have an external battery, two screws hold the battery on the bracket.
These are either security hex or regular hex.
This will expose 3 more screws.
Take care removing these screws as they strip very easily.
The bracket may be slightly stuck but once these 3 screws are out it can be removed.
If you do not have a bracket then you will have three screws holding the battery in place within the pole.
You will also have a charging port cover to remove.
Remove the top cover to reveal two screws holding the cover on.
Finally, one more screw holds the ESC in place on the pole.
Next comes arguably the most annoying part of the disassembly, removing the waterproofing grommets.
On the top and the bottom is two grommets that are twisted in place.
Press down hard with a large flathead screwdriver and twist counter-clockwise until the slots line up with the metal ridge within the pole.
In some cases, pushing the rubber inner part through the plastic retainer ring will make it easier to remove.
Attempt to keep the wires pushed through the rubber part.
Once both are separated the whole mechanism slides easily out of the pole unless the pole has been damaged or bent.
A plastic holder clips the battery and ESC together.
Separate the ESC from the battery and carefully unplug the 4-pin data cable and the power cable.
Reassembly
Start by placing the plastic battery-ESC clip into the battery.
Thread the dashboard cable through the power cable on the battery.
Plug in the 4-pin data line.
Plug in the power cable.
Feed the loose dashboard cable until it is mostly tight.
Clip the ESC to the battery.
Press firmly to reinstall the dashboard cable into the channel, pulling the dashboard cable tight.
Slide the battery and ESC into the pole.
Align the charging port and insert the small screw.
If using an external battery, use Loctite/thread lock on the 3 holes.
Take care reinstalling the 3 bracket screws as they strip very easily.
If you do not have a bracket then you will have three screws holding the battery in place within the pole.
You will also have a charging port cover to reinstall.
Install the two screws and the cover.
If you have an external battery, two screws hold the battery on the bracket.
These are either security hex or regular hex.
Plug in the dashboard cable to the dashboard in the handlebar.
Test that the scooter still functions before continuing with assembly.
Reinstall the 4x Security Torx T25 screws or Hex Screws that hold the handlebar in place on the pole.
Reinstall the 4x Security Torx T30 screws or Hex screws that hold the pole to the base.
Check that the scooter is sturdy and nothing is loose.
