DC-DC Chargers for Smarter Dual Battery Charging for 4WD, Caravan, RV & Marine

Your alternator alone isn't enough to fully charge a modern lithium or AGM auxiliary battery — especially with smart alternators that cut voltage early. A DC-DC charger bridges that gap, drawing power from your starter battery and delivering a properly regulated, multi-stage charge to your second battery while you drive.
Whether you're building a 4WD canopy setup, a caravan power system, or a marine dual battery install, our range covers everything from compact 10A units to full 40A+ systems with built-in MPPT solar input,  so you can charge from alternator, solar, or both simultaneously.

  • Compatible with lithium (LiFePO4), AGM, GEL & lead-acid batteries
  • Works with smart/variable voltage alternators
  • Dual input — alternator + MPPT solar in one unit
  • Trusted brands: Enerdrive, Projecta, Intervolt, HULK, Victron & iTechworld
  • 10A to 100A ratings — solo units to complete power system kits
  • Free shipping on orders over $200
