Our customer wanted to update the battery set up on his Ford Ranger. He had been trying to charge his auxiliary battery from his alternator via a battery isolator. However, this was becoming ineffective and he needed a more reliable option. Our Auto Electricians supplied and installed a Thunder battery box and a DCDC charger. The Thunder Battery Box provides 12 volt power for common devices and appliances, acting as a dual battery system to manage solar and in-vehicle charge. This battery box along with the DCDC charger will allow our customer to charge all his devices and fridges to ensure comfortable camping trips.
