Why I Recommend Investing in a Dual Battery Isolator Kit

As someone who loves to go on outdoor adventures and frequently uses my vehicle for camping and off-roading, having a dual battery isolator kit has been a game changer. It has not only made my trips more convenient but also provided peace of mind.

One of the main reasons why I highly recommend investing in a dual battery isolator kit is its ability to power multiple accessories without draining the main battery. Whether it’s running a fridge, charging phones or using lights, having a separate battery specifically for these purposes ensures that my main battery remains fully charged. This means I never have to worry about getting stranded due to a drained battery.

Another benefit of having a dual battery isolator kit is its versatility. Most kits come with an automatic charging relay that allows the auxiliary battery to charge while the vehicle is running. This means I can go on longer trips without having to worry about finding an external power source to recharge my batteries.

Moreover, the installation process of a dual battery isolator kit is relatively simple and can be done with basic tools. I was able to install mine within an hour without any prior experience or professional help. This not only saved me money but also gave me the satisfaction

My Buying Guide on Dual Battery Isolator Kit

As someone who loves to go on long road trips and camping adventures, having a reliable and efficient power source is crucial for me. That’s why I decided to invest in a dual battery isolator kit for my vehicle. After doing extensive research and trying out different brands, I’ve come up with this buying guide to help you choose the best dual battery isolator kit for your needs.

What is a Dual Battery Isolator Kit?

A dual battery isolator kit is a device that enables you to have two separate batteries in your vehicle, one for starting the engine and the other for powering auxiliary devices like fridges, lights, or winches. It works by allowing power to flow from the alternator to both batteries simultaneously but prevents them from draining each other.

Why Do You Need a Dual Battery Isolator Kit?

If you’re someone who loves off-roading, camping, or any other activity that requires you to be away from civilization for an extended period, then a dual battery isolator kit is a must-have. It ensures that your vehicle’s main battery always has enough charge to start the engine while providing power to your auxiliary devices without draining it.

Factors to Consider

When looking for a dual battery isolator kit, there are some essential factors that you should keep in mind:

1. Type of Isolator

There are two main types of dual battery isolators: solid-state and electro-mechanical. Solid-state isolators use electronic components and are more efficient and reliable than electro-mechanical ones. However, they tend to be more expensive. Electro-mechanical isolators use mechanical relays and are more affordable but less efficient.

2. Number of Batteries Supported

Dual battery isolators can support anywhere from two to four batteries depending on the brand and model. Before making a purchase, make sure the kit can support the number of batteries you need for your setup.

3. Amperage Rating

The amperage rating of an isolator determines how much current it can handle without overheating or causing damage. Make sure to check if the amperage rating is suitable for your vehicle’s electrical system.

4. Warranty

It’s essential to choose a dual battery isolator kit that comes with a warranty. This will give you peace of mind knowing that if anything goes wrong with the product within the specified time frame, it will be covered by the manufacturer.

My Top Recommendation: The Redarc Smart Start SBI12 Dual Battery Isolator Kit

After trying out different brands, I highly recommend the Redarc Smart Start SBI12 Dual Battery Isolator Kit. It’s made of high-quality materials and has an amperage rating of 100 amps – perfect for my off-grid adventures.

Moreover, it supports up to four batteries and comes with a five-year warranty which gives me confidence in its durability and reliability.

In conclusion, investing in a quality dual battery isolator kit is vital if you want uninterrupted power supply during your outdoor adventures. By considering factors like type of isolator, number of batteries supported, amperage rating, and warranty before making a purchase decision, you’ll be able to choose the best kit that suits your needs perfectly. Happy shopping!
