Adding a second battery prevents getting stranded with a dead battery by isolating the start battery from the house loads that can quickly discharge a battery. The Add-A-Battery offers a simple way to control switching with the Dual Circuit Plus„ Battery Switch and automatically share a single source of charging between two batteries with the ACR.
The kit includes a Dual Circuit Plus„ Battery Switch and an Automatic Charging Relay simplifying switching & automatic charging, so that you just turn the battery switch ON when you board and OFF when you leave.
