Blue Sea ML-ACR
The Blue Sea Systems 7622 ML-ACR is the most robust, reliable, dual-voltage sensing "smart relay" on the market. This is why we have chosen this workhorse to be the heart of all of our dual battery systems.
This 500 amp, dual voltage sensing, "smart" relay automatically combines batteries during charging and isolates batteries when discharging, making it ideal for automotive dual battery systems.
This particular model of the ML-ACR (7622-100B) has a pre-installed Deutsch connector, making it the perfect "plug-and-play" companion to our exclusive wiring harness.
*Wiring harness sold separately or as part of our complete kit.
