Blue Sea Systems Solenoid Add A Battery Mini 65A

Blue Sea Systems Mini Add-A-Battery Kit 65A (7649)

The Blue Sea Systems 7649 Mini Add-A-Battery Kit is a premium dual-battery management solution designed for small boats, RIBs, center consoles, and vessels equipped with outboard engines up to 65A alternator output. The kit combines the proven m-Series Dual Circuit Plus™ Battery Switch with the reliable 65A Automatic Charging Relay (M-ACR), creating a simple, fully automated charging and battery isolation system.

This intelligent system automatically combines both batteries during charging and isolates them when the engine is off, ensuring your starting battery remains protected while onboard electronics continue to operate safely. The integrated emergency combine function also allows both batteries to be connected for emergency engine starting.

Designed for marine environments, the system features ignition-protected construction, corrosion-resistant tin-plated copper terminals, and compact dimensions for easy installation in tight spaces. The Mini Add-A-Battery kit eliminates complicated manual switching procedures and provides safer, more efficient dual-battery charging without rewiring or regulator modifications.
