Recoil SRL500 500A Smart Battery Isolator and High Current Starter Relay

Recoil SRL500 Microprocessor Controlled 500A Smart Battery Isolator and High Current Starter Relay, Dual Sensing Smart Relay, with Ring Terminals

• SRL500 handles 500 Amps continuous at 12V and 700 Amps Surge. Microprocessor-controlled smart relay does not create a voltage drop to the second battery like conventional isolator.
• Eliminates multiple battery drain as it stops battery bank from getting power from each one and extends battery life. Prevents the equipment from discharging the main battery when it is operated while the engine is off.
• 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 auxiliary battery is charged by 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.

Recoil’s smart battery isolators are microprocessor controlled high current relays used in dual battery systems. They are designed to be used as a solenoid priority system to protect the main battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads.

The dual sensing smart isolators have the added feature of allowing charge both ways where the auxiliary battery may also be charged by an external source, such as solar panels or an external AC battery charger. They will also allow the main battery to be charged by the external source once the auxiliary battery reaches 13.2 volts to help top up the main battery.
