Battery to battery chargers (DC-DC) provide controlled, efficient charging of auxiliary batteries from a vehicle’s main electrical system, ensuring stable power for onboard equipment in commercial fleets. Our range includes smart multi-stage DC-DC units, dual-input chargers, intelligent alternator-compatible models and options suitable for both 12V and 24V systems. Each charger is engineered for reliable performance, protecting batteries from undercharging or overcharging while supporting demanding trade installations.
Used across vans, HGVs, welfare units, mobile workshops, plant machinery and specialist vehicles, DC-DC chargers maintain consistent auxiliary power for lighting, tools, PTO systems, inverters and onboard electronics. With robust housings, vibration-resistant construction and advanced power management designed for harsh operating environments, we help fleet operators maintain safe, efficient and compliant battery support throughout their vehicle networks.
