The Ring DC battery charger takes the energy from a vehicle's main battery (engine running) and converts it into multi-stage output for charging an auxiliary battery. Input voltage (starter battery bank) can be between 12v - 50v and output is 12 volts to charge a 12v leisure / auxiliary battery bank.

Compensates for high voltage or a drop in voltage to maximise charge to auxiliary battery. Programmable for most battery types. 3-Stage smart charge output for optimal battery performance. Suitable for battery banks from 40-500Ah.

Will work with smart alternators to deliver accurate charging voltage. Low battery shut off to protect main battery. Sleep mode to eliminate battery drain.
