Stinger SGP35 500 Amp High Current Relay and Isolator

The Stinger SGP35 is a 500 Amp High Current Relay and Isolator designed to manage secondary battery systems in automotive applications. This robust device prevents the primary battery from discharging by isolating the secondary audio battery from the vehicle's electrical system, ensuring the main battery retains its charge for essential vehicle functions.

Ideal for 2nd audio battery isolation, Stinger's high current relays are a reliable and efficient way to add secondary batteries to your system. It is compatible with all types of alternators and charging systems, offering universal 12V compatibility. The unit is constructed from water-resistant black phenolic plastic, ensuring durability and a long-lasting mechanical cycle life of 100,000 cycles.

The SGP35 provides maximum current transfer, delivering power on demand with a constant current rating of 500 amps and a peak current of 900 amps. This makes it suitable for high-demand applications involving secondary battery setups, such as those found in 4x4 overlanders, off-roaders, and high-performance audio systems.
