Go above, beyond, and over-prepared, with the Under Bonnet 40A DC-DC Battery Charger with MPPT Solar Regulator by Hardkorr!

From weekends away to off-grid getaways, this charger is ideal for Lithium, AGM /Gel, Lead Acid, and Calcium battery setups. Owing to its compatibility with traditional or ‘smart’ vehicle alternators, it will boost your batteries while you drive at 40 Amps every hour, converting the power from your alternator into a voltage that both safely and swiftly suits your auxiliary battery’s status and chemistry without affecting the starter battery. An inbuilt MPPT regulator also brings your batteries back to full charge by detecting the solar power input as either the sole source, or greater than that produced by the vehicle. With a compact construction for mounting in tight under-bonnet nooks too – this kick-butt battery gadget is ideal for fitting in engine bays or 4WD canopies.
