Take control of your vehicle’s power management with the Powertech Dual Battery Isolator Kit, designed to keep your starter battery protected while ensuring consistent power delivery to your auxiliary systems.

Key Features

Automatic Battery Isolation: Prevents auxiliary loads from discharging your main starter battery.

Voltage Sensitive Relay (VSR): Automatically connects/disconnects the auxiliary battery based on voltage levels (13.3V cut-in, 12.8V cut-off).
Weather Resistant: IP65-rated for dust-tight and water-jet resistant protection.
Complete Kit: Includes marine-grade wiring, hardware, and easy-to-follow installation instructions.
Easy to Install: Designed for simple DIY or professional installation in 12V systems.
