Mercedes G Class Dual Battery Kit

G-Class Off-Grid Dual Battery Power System

The Overland-G Off Grid Dual Battery Power System defines how electrical energy is stored and distributed in Mercedes G-Class expedition builds.

System Architecture

The system separates engine starting from auxiliary power usage. The primary battery is reserved for starting, while a secondary battery system powers onboard equipment.

Dual Battery Layout

The dual battery configuration is installed in the rear cargo area, creating a dedicated space for energy storage and distribution.

Mounting System

The Dual Battery Mounting Box provides structured installation for batteries and electrical components.

It also allows integration of additional equipment depending on the build.

Electrical Control

The Dual Battery Electrical System Kit manages power flow between systems.

It includes relays, fusing and distribution components required for stable operation.

Power Usage

The system supports operation of auxiliary equipment, including:

• Lighting systems
• Refrigeration units
• Onboard compressors
• Navigation and communication equipment

System Role

This configuration ensures that auxiliary power demand does not affect engine starting capability.

Compatibility

Compatible with Mercedes G-Class platforms W460, W461 and W463 depending on electrical setup and vehicle configuration.

Application

Used in builds where reliable off-grid power supply is required for expedition and overland use.
