Blue Sea Battery Management Kit 120A, Dual Circuit Plus Battery Isolator System, Easy Battery Charging

The ADD-A-BATTERY is as simple to use as an ON-OFF switch, but effectively manages the switching and charging of two batteries from a single charging source.

The Add-A-Battery includes a Dual Circuit Plus™ battery switch and an automatic charging relay. These components simplify switching and automate the charging process, so all you have to do is turn the battery switch ON when you arrive and OFF when you leave.
