MAIN FEATURES
The BRL80 Battery Isolator is a powerful and reliable device made for vehicles with two batteries, such as camper vans, trucks, boats, or off-road vehicles. It’s designed to safely manage power between your main battery (used to start your engine) and a secondary battery (used to run extra equipment like lights, fridges, or sound systems).
This isolator can handle up to 80 amps of power continuously at 12 volts, and up to 150 amps during short bursts or surges—which means it’s built to support demanding accessories and devices without overheating or failing.
One of the most useful features of the BRL80 is that it prevents your batteries from draining each other. When your engine is off, it stops power from flowing between the batteries, so your main battery won’t be drained by anything running off the secondary battery. This keeps your vehicle ready to start, even if you're using power-hungry equipment while parked.
It also protects your main battery from being drained by lights, fridges, or other gear if you're using them while the engine is turned off. That way, you don’t get stranded with a dead battery.
Unlike some older battery isolators, the BRL80 does not cause a voltage drop to the second battery. That means your second battery charges faster and more fully, making better use of your alternator’s power and helping your batteries last longer.
Built with durability in mind, the BRL80 has a waterproof and weather-resistant design, making it a great choice for any outdoor or off-road setup. Whether it’s hot, cold, wet, or dusty, this isolator is made to keep working reliably.
Overall, the BRL80 is an excellent solution for anyone looking to run extra equipment from a second battery without risking the power needed to start the vehicle. It extends battery life, simplifies your power setup, and works in all kinds of weather and environments.
