Ranger Model
  • Route Package Protection

The Ranger is a Plug and Play battery solution for the Super73 ZX, S2, R, & RX. With the ability to double your range, The Ranger helps squash range anxiety and keep the adventure going.

What does Plug and Play mean? It means there are no modifications needed to use this battery. Install or remove the whole system with ease. The Ranger works in tandem with your stock battery - they charge together and drain together. Built with the stock battery connector and charge port, The Ranger provides the best compatibility available - no need for a new charger!

The only difference between the two batteries models is the battery tray that holds the Ranger, since the ZX uses a different connection than the others. Otherwise, both battery models are identical. 

This Battery is made to order and is expected to ship in 2-4 weeks. Orders are fulfilled in the order they are placed. Lead-time may change depending on order volume. Thank you for your understanding.

Order cancelation requests after 72 hours may be subject to a 25% re-stocking fee.


  • Plug and Play battery upgrade
  • Doubles your bikes capacity from 20 Ah to 40 Ah (S2, R, RX)
  • Over doubles your range for the ZX and Z Miami
  • Original Super73 battery connector and charge port
  • Easily mounts in the bike frame
  • Works with stock charger and our Super Fast Charger

Install is easy - 2 screws to secure the mount and a few zip ties to secure the cable. The splitter cable that comes out of the mount uses the same connectors as stock, so it only takes a few moments to connect.

Use & FAQ

How do I connect the battery safely?

Due to the nature of parallel batteries, you want to make sure both batteries are fully charged before connecting and riding. When the light on your charger turns green you will know they are fully charged. Make sure both batteries are turned on before riding.

Why do both batteries need to be fully charged before connecting? 

Connecting at different voltage levels causes an influx of current to the battery with less charge. That influx of current can damage both batteries.

How do I power the system on? 

Power on your stock battery first and then power on the Ranger.

How do I power the system off? 

Power off the Ranger first and then power off the stock battery.

What if I do not follow the power sequence? 

We have found it can sometimes (not all the time) result in a glitch where the display will not turn on and the trigger will not engage. Power the whole system off and then back on again in the correct order to resolve the issue. If this does not work then wait a few minutes and try again.

Can The Ranger replace my stock battery entirely? 

No, the stock battery is still required because the battery management system in the stock battery is key to the functionality of the bike.

How does charging work? 

The Ranger comes with the same charge port as the stock battery which means it can be charged by your stock charger. When the batteries are connected on the bike, plugging one charger in will charge the whole system together.

When both batteries are attached to the Super73:

  1. Turn ON Stock Battery
  2. Turn ON Ranger
  3. Plug charger into the Stock Battery
  4. Both batteries will charge and charge icon will display on bike screen
  5. Disconnect charger
  6. Turn OFF Ranger
  7. Turn OFF Stock Battery (if fully charged stock battery will have turned off automatically)

How long does it take to charge?

Since you now have double the battery capacity, you will also have double the charge time.

Will the Ranger increase my top speed? 

No it will not. The Ranger is a range modification. To increase the speed you would need to use a different controller - but you may see better performance and less voltage sag when the battery is low.

What does the I and O represent on the Ranger Power Button? 

The “I” on the Ranger power button represents ON and the “O” on the Ranger is OFF.

What is the square block on the splitter? 

The block is a relay! We changed the design of the Ranger with an added relay to improve the safety and performance. You can easily tuck the relay underneath your seat to hide it!

The “mileage till empty” reading on my display says I am getting the same range I would get with my stock battery. What gives? 

The mileage reading will no longer be accurate with the Ranger installed. However, what will be accurate is the ring around the display and the percent reading in the Super73 App. It is best to base your range off of those features.

Will the stock battery drain faster than the Ranger? 

The Ranger and your stock battery should charge and discharge at the same rate. Just make sure they are at the same voltage when hooking them up together!
