Blue Sea ML-ACR with OGE Wiring Harness and Switch
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.
When paired with the Blue Sea Systems switch and our exclusive "plug and play" wiring harness, the ML-ACR can be manually controlled from your drivers seat! Combine batteries for jump starting yourself, winching, or other high amp draw scenarios. Manually isolate batteries for extra piece of mind at camp. Or, simply place in "auto" mode for a worry free setup.
The Blue Sea Systems 2146 switch has built in LED's that illuminate when batteries are combined or flash to alert for potential problems with your battery system.
