Blue Sea System's CL-Series BatteryLink Automatic Charging Relay (ACR) will ensure that you never have a dead battery again. The BatteryLink ACR is smart enough to sense different charge voltages on up to two different battery banks. It's slim design and noise free operation will not interfere with other devices.
This Automatic Charging Relay meets SAE J1171 external ignition protection requirements which makes this product safe aboard any gasoline powered boat. This relay automatically closes when the higher battery has remained at a preset voltage level for at least 30 seconds. The BatteryLink ACR also automatically combines each battery bank during the charging cycle, and isolates them during a discharge. This product is easy to install and can be activated from any power source (solar panels, battery chargers, alternators, etc.)
