Battery Isolator Switch Solenoid HD 100amp continuous | Isolators

$99.00
Description

The 100A Continuous Battery Link Solenoid is a 12V DC dual battery isolator designed to protect your start battery from discharge while allowing your auxiliary battery to power non-essential loads. Ideal for 4WD and commercial vehicles, this isolator includes electronic components that suppress high voltage transients and provides superior performance over traditional diode-based systems.

This heavy-duty solenoid features thick copper terminals for reliable current transfer, low-power coil consumption, and a durable, high-temp flame-retardant housing. It prevents your accessories from draining the main battery when the engine is off—keeping you ready to go.
