WHOOP Battery Pack 4.0
The battery pack houses the inductive charging coil and the power management IC (PMIC) necessary to negotiate a charge with the strap sensor. A 'red light' often indicates a failure in the pack's internal lithium-polymer cell or a firmware-induced lockup in its proprietary charging protocol, which prevents the secondary inductive coil from generating the required electromagnetic field to wake the sensor. Replacing the pack ensures a known-good power source with updated firmware capable of initiating the handshake.
