Dual Battery Systems
All dual battery systems are different, they depend on your vehicle, caravan or camper and your usage requirements. We can size your system to suit you, whether it's an under-bonnet system, a tray-back or canopy system, or just the existing battery system in your camper. It should have isolation from your 'starting battery' and may incorporate solar panels or chargers, and various connections to what you are using. ie. 12v fridge and lights.
Charge your Dual Battery System via your vehicle's alternator, a 240v Battery Charger, or Solar. Your Dual Battery System may require a DC-DC charger for vehicle charging. Many late-model vehicles have ‘variable voltage’ or ‘temperature compensating’ alternators. These late model alternators are not capable of fully charging a second or third battery due to lower voltage outputs. To see what alternator is on your vehicle, see Redarc's Dual-Battery Calculator, and select your vehicle.
