Education & Resources
Understanding how your 12-volt power system works is key to keeping lights, fridges, and tools running off-grid. In a dual-battery setup, a DC-DC charger pulls energy safely from your alternator while isolators prevent back-feed to your starter battery. Add a solar charge controller and you’ll have renewable, continuous charging for longer stays on the trail.
