FAQs Summary:

Why It’s Needed:

Most motorhomes only charge the leisure battery when plugged into mains or running the engine. The engine battery is often neglected, leading to deep discharge from minor drains (e.g., alarms, clocks). Left flat, a battery often becomes unusable.

Battery Master solves this by ensuring the engine battery is topped up automatically, without manual intervention or risk to the vehicle’s electronics.

If you’re leaving your motorhome idle for weeks or months — particularly off-grid — the Battery Master is a smart, low-cost insurance against the hassle (and expense) of a dead engine battery.
