Product Overview

Complete kit simplifies battery management.

Blue Sea Systems has led the charge to make battery management easier. The Mini Add-A-Battery Plus Kit takes it to the next level and streamlines installation and simplifies use. The kit provides complete control of two batteries and offers two ways to charge them. And it’s done with just three components: a battery charger, battery switch and charge status indicator display.

Battery charging is handled in one of two ways. From the dock or at home using an AC power source or from the engine’s alternator. Using household or dockside power the 10A multi-stage charger safely and efficiently recharge the batteries. A temperature compensation features modifies charging amperage based on battery temperature to prolong battery life.

Unique to the Blue Sea System charger is a built in automatic charge relay (ACR). This allows an alternator up to 65A to charge two batteries while you’re out on the water. The ACR also protects sensitive electronics and other equipment by temporarily isolating house circuits from start circuit during engine starts.

Easy to use battery switch turn on both batteries with a quarter turn. This three position switch keeps the house and start batteries separated to prevent accidental discharge. An emergency combine feature allows the battery with a charge to start the engine or power the VHF.
