Compact in size and easy to install, the new Thunder DC-DC Charger is the smart way to charge your auxiliary battery, no matter your vehicle.
Utilising a unique pulse charging algorithm with the intelligence to determine the best charge rate for your auxiliary battery, this charger is the perfect addition to any
vehicle requiring the management of a dual battery setup.
One of the greatest features of the new DC-DC Battery Charger, is the new remote Bluetooth LCD screen; giving you better visibility on your battery’s state of charge.
Grow as your needs change
The new charger also features Modular Sense Technology (MST) allowing you to link multiple units together giving you a 20, 40 or 60A output without having to outlay for a larger unit upfront.
As your needs increase you can steadily increase your charge rates.
Suitable for Gel, AGM, Calcium, Lead Acid and now Lithium batteries, Thunder’s new DC-DC Charger is an ideal addition for caravans, camper trailers and 4WD’s.

Integrated Bluetooth LCD Screen
The remote LCD interface screen gives you better visibility on your battery’s state of charge, without looking directly at the unit. This design, its IP67 rating and 90°C operating temperature means the charger can be installed in an engine bay with a reduced likelihood of it de-rating due to the harsh under bonnet environment, with the display in the cabin.
While your vehicle is charging, the LCD screen will show the Vehicle Car Charge screen, allowing you to see the main and auxiliary battery voltages, auxiliary battery percentage and how much current is flowing into the battery. It will also show if Lithium mode is being used.
After the vehicle’s engine has been turned off and the battery voltage in the main battery has reached a loaded voltage of 12.2V, the LCD screen will move to the Solar Charge screen showing battery voltages, percentages and the flow of the solar charge.
