Stinger SGP38 80 Amp Battery Isolator/Relay

The Stinger SGP38 is an 80 Amp Battery Isolator/Relay designed to efficiently manage dual battery systems in vehicles. It serves as a reliable solution for adding secondary batteries, preventing the primary battery from discharging and ensuring maximum current transfer to your accessories.

This high-current relay is compatible with all types of alternators and charging systems. When installed, it automatically connects the two batteries when the vehicle is running and disconnects them when the vehicle is off, allowing you to power accessories from the secondary battery without draining the primary battery for safe starting.

Constructed from water-resistant black phenolic plastic, the SGP38 is built for durability and boasts a mechanical cycle life of 100,000 cycles. It is an ideal component for isolating a second audio battery from the vehicle's main electrical system, making it suitable for high-performance audio setups, 4x4 overlanders, and offroaders.
