Add-A-Battery System
Simplified Dual Battery Management
Overview
The Add-A-Battery system is as simple to use as an ON-OFF switch, yet it intelligently manages the switching and charging of two batteries from a single charge source.
Just turn the switch ON when you arrive and OFF when you leave—the system takes care of the rest.
