Choose the correct generation

The original B37 uses a round barrel charging socket and push-fit heads. B37 v2 uses USB-C charging and locking heads. Bantam hardware and indicator lights have also changed over time. Identify your device by its physical port and controls; purchase date alone may not identify the version.

If the displayed manual does not match your device, email [email protected] with a photo of your charging port and controls so we can help select the correct instructions.
