The Blue Sea Systems Mini Add-A-Battery Kit provides a complete dual battery management solution designed to prevent dead battery situations by isolating your starting battery from house loads. This compact system combines an m-Series Dual Circuit Plus™ Battery Switch with a Mini ACR (Automatic Charging Relay) to intelligently manage two batteries from a single charging source.

Key Features:

• Automatically isolates starting battery from house loads to prevent being stranded
• Includes m-Series Dual Circuit Plus™ Battery Switch for manual battery selection
• Integrated Mini ACR Automatic Charging Relay shares charging between both batteries
• Compact design ideal for space-limited installations in boats, RVs, and vehicles
• Boxed packaging includes all necessary components for complete installation
• Eliminates the need to manually switch batteries while ensuring both stay charged

This kit is ideal for marine, RV, and automotive applications where a dedicated starting battery and separate house battery system is needed. The automatic charging relay intelligently connects batteries during charging and isolates them when the engine is off, providing worry-free dual battery operation.
