Battery Pack 4.0 Updater

At WHOOP, we are always looking for ways to improve our technology and the experience we provide our members. Just like the WHOOP 4.0, the Battery Pack 4.0 is a smart, sophisticated piece of technology that is capable of being updated with new functionality and performance improvements.

The instructions below will guide you through the process of updating the firmware on your Battery Pack 4.0, which will provide you with the most up-to-date experience. 

Getting started

To update your Battery Pack 4.0, you will need: 

  • A laptop or desktop computer
  • Your Battery Pack 4.0
  • Your WHOOP USB-C cable to connect the Battery Pack 4.0 to the computer

Please note: The Battery Pack 4.0 Updater is only available for Macs running macOS version 10.15 or later and PCs running Windows version 10 or later. It will not function on Chromebooks, iPads, iPhones, or other devices.

Troubleshooting

Note: If your Battery Pack 4.0 is operating as expected, updating its firmware via the Battery Pack 4.0 Updater is not required.

  1. Try a different USB Port on your computer.

  2. Restart your computer.

  3. Try both of these variations: have the BP connected then open the program. Next, try opening the program without the BP connected to your computer, and once the program is open attach it.

 

What to do if your computer doesn't detect your Battery Pack 4.0

If the updater doesn’t detect your Battery Pack 4.0 when you plug it into your computer, please ensure that you’re using your WHOOP-provided USB-C cable. Next, with the Battery Pack 4.0 Updater application open, unplug your Battery Pack 4.0 from the computer and plug it back in.

 

What to do if the firmware update fails

If a firmware update fails, please close and re-open the Battery Pack 4.0 Updater application, unplug your Battery Pack 4.0 from the USB-C cable, plug it back in, and select Start Update.

If the update fails after following these steps a second time, reach out to Membership Services by submitting a request.
