Enerdrive Add-A-Battery Mini Dual Battery Charging System

The Enerdrive Add-A-Battery Mini is a simple, integrated solution for managing and charging two batteries from a single charging source. Designed for marine electrical systems, it combines a Dual Circuit Plus™ Battery Switch with an Automatic Charging Relay (ACR) to simplify battery switching and automate charging.

The system isolates the engine and house circuits during normal operation, automatically combines batteries when charging, and allows the batteries to be combined for emergency starting. The ACR also isolates the batteries during engine cranking and when charging is not occurring.

Easy to operate, the Add-A-Battery Mini requires only switching the battery switch ON when arriving and OFF when leaving, providing efficient dual-battery charging without requiring regulator adjustments or rewiring.
