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.

Thunder dcdc charger for the win!!
By: David Romanin on8 March 2023
I recently added the Thunder DCDC charger to my auxiliary battery. The unit is compact and lightweight and so very easy to install. The addition of the Bluetooth screen makes this little unit a must have. I gave it a good test on my recent trip down in the south west of WA. It didn’t skip a beat and kept my battery charged without worry. Highly recommend this product to anyone considering adding to their setup.
On the hunt for a DCDC charger
By: Leroy Williams on12 January 2022
I was looking for a DCDC charger, and also wanted to keep an eye on the state of charge of my starter battery. This new Thunder charger was able to do both so I grabbed it. Love the under bonnet mount and remote monitoring screen.
