SRL500 Microprocessor Controlled 500A Smart Battery Isolator and High Current Starter Relay, Dual Sensing Sma...

Description SRL500 handles 500 Amps continuous at 12V and 700 Amps Surge. Eliminates multiple battery drain as it stops the battery bank from getting power from each one and extends battery life. It prevents the equipment from discharging the main battery when it is operated while the engine is off. Microprocessor-controlled smart relay does not create a voltage drop to the second battery like a conventional isolator. Once the main battery reaches 13.2V, the smart relay connects two batteries. Once the system drops below 12.7V, it disconnects two batteries. The dual sensing feature allows charging both ways if the auxiliary battery is charged by the external power source. A waterproof manual override switch allows you to connect two batteries with the push of a button for 60 seconds. Excellent waterproof performance, high quality in any weather conditions. Two 1/0AWG copper ring terminals and heat shrink tubing are included for easy installation.
