Sure Power, 1315A | 12-Volt 100-Amp Bidirectional Battery Separator

SPECIFICATIONS :

• Voltage : 12 Volts DC
• Amperage : 100 Amps

FEATURES :

• Auxiliary Start-Assist : (Start Signal must be at least 3-volts to occur)

When the starter is activated, the Battery Separator (1315A) compares the voltage of both your battery banks (Main & Auxiliary). If the Main battery is at a lower power than the Auxiliary battery bank, the solenoid will engage, and connect both batteries to each-other for added starting power.

Protects Charging System :

Once the engine has started, the Battery Separator (1315A) monitors the chassis battery and charging system. When the charging system brings the Main Battery to 13.2 Volts (indicates full-charge), the Solenoid will "Close" which allows current to pass to your Auxiliary Battery. If the drain on the charging system (caused by charging the Auxiliary battery) brings the charge voltage below 12.8 volts, the Solenoid will "Open", which disconnects the Auxiliary battery from charge. It will then bring the Main Battery back to full-charge state (13.2 to 13.4 Volts), it will again "Close" and make the attempt again. This process is repeated until the charge source is removed (turned off). This function protects your charging source, by never allowing it to work itself to "Death" prematurely.
