VEVOR 12V 30A DC-DC Battery Charger 375W
A simple relay won't charge your aux battery properly on the road. This VEVOR 30A DC-DC charger uses smart multi-stage charging to keep your AGM, lead-acid or lithium battery in top condition.

Running a second battery in your caravan, camper trailer, 4WD or boat setup means you need a reliable way to charge it while the engine is running — and a basic connection to the starter battery just doesn't cut it. The VEVOR 12V 30A DC-DC charger is designed for exactly this job, converting alternator output into a controlled 12V charge for your auxiliary battery at up to 375W.
The multi-stage charging logic is what sets this apart from a simple relay or VSR setup. For lead-acid and AGM batteries, it runs a full 3-stage charge cycle — bulk, absorption and float — to bring the battery up properly and maintain it without overcharging. For LiFePO4 lithium batteries, it uses a 2-stage process suited to the different chemistry. The result is a longer-lasting battery that charges correctly every time.
Built-in protections cover the key failure points: over-voltage, under-voltage, high temperature and reverse polarity. Isolated input and output mean your vehicle's primary electrical system stays clean and interference-free. The lithium battery activation feature is a useful extra — it can revive deeply discharged lithium cells that have dropped below normal charge thresholds.
The aluminium alloy housing handles heat well in engine bay or under-floor installations, and pre-drilled mounting holes make fitting straightforward in tight spaces. A solid upgrade for any dual-battery system.
