Greenworks 80V 4.0Ah Lithium-Ion Battery
The 5-second delay suggests the mower successfully completes its handshake and soft-start but fails once the motor controller attempts to reach full operational RPM. High internal resistance in the battery cells causes a voltage sag under the high torque load of the blade; the BMS triggers a protective shutdown because the terminal voltage drops below the safety threshold. Replacing the battery pack is the standard resolution for this specific timed-shutdown profile.

Brushless Motor Controller Assembly
The controller regulates the three-phase power to the brushless motor and monitors thermal and load data. If the MOSFETs within the controller are failing or if the logic board has a thermal fault that manifests under load, it will interrupt the circuit shortly after the startup sequence. This is the primary failure point if a known-good battery does not resolve the shutdown.

Wiring Harness Connector Kit
Oxidation or arcing on the high-current battery terminals can create a high-resistance junction. As heat builds up over the first 5 seconds of operation, the resistance increases, causing a voltage drop that mimics a failing battery and triggers the system's safety cutoff.
