12V 45A Carspa DC DC Smart Charger

This 45A DC to DC charger (including PWM Solar charging) by Carspa will charge your 12v battery from either your 12v starter battery or a solar panel.   It can charge conventional Flooded Lead Acid, Calcium, AGM VRLA & GEL and Lithium batteries.

The advanced micro-processor control and hardware based protections will only draw from the starter battery when it is over 12.9V, ensuring it is kept fully charged to always start your vehicle.
