DETAILED DESCRIPTION

Reliability and Protection

The Battery Box is designed to protect your Foil Assist system's battery in the marine environment. Its tough plastic construction and waterproof seal, combined with a secure sliding lock, prevent water ingress and reduce the risk of it opening accidentally while you're on the water.

Ergonomic Installation

The box attaches to your eHarness with four screws, ensuring optimal load distribution. The mounting system is designed to be discreet and stable on your harness, while still allowing quick access to the battery compartment when needed.

Pressure Management and Internal Safety

A Gore-Tex valve on the back prevents pressure buildup inside the box while keeping it waterproof. The integrated receiver in the lid ensures a solid electrical connection and protects all contacts from spray.

Use and Compatibility

This spare part is exclusively for users of the Duotone Foil Assist system and the eHarness. The battery itself, the harness, and the charger are sold separately; we recommend using only compatible Duotone batteries.
