12V DC-DC On-Board Battery Charger with MPPT 50A/30A

Renogy 12V On-Board DC-DC Battery Charger with MPPT 50A/30A is a multi-stage, multi-input battery charger that can charge a leisure battery from a starting battery linked to an alternator or by utilizing solar panels connected directly to the unit. While your vehicle's alternator prioritizes your starting battery, this unit will allow your solar system to charge your leisure battery first! It's the smart way to keep yourself fully charged and off-grid longer!
