Elevate Your 4×4 Adventures with a Voltaic Auto Electrical Dual Battery System

If you constantly worry about draining your battery while on an adventure or camping, here is how to kick your 4×4 adventures into high gear. With the game-changing Voltaic Auto Electrical‘s dual battery system, now you can explore rugged terrains, conquer off-road challenges and camp in the great outdoors, knowing your vehicle’s electrical system is reliable and robust.

Below is an electrifying guide to help you understand what a 4×4 dual battery system is, how it works and how it will upgrade your 4×4 adventures.


What is a Dual Battery System?

With accessories like winches, fridges, lighting and communication devices, your 4×4 needs extra power to stop draining the main battery. A dual battery system involves installing an additional battery in your vehicle so that your vehicle’s starting battery remains isolated and unaffected by the power consumption of these additional accessories.

So how does the whole setup work?


How Does a Dual Battery System Work?

Typically, a dual battery consists of the primary battery, the auxiliary battery and an isolator. The isolator, also known as a voltage-sensitive relay (VSR), acts as a bridge between the two batteries. It allows power to flow from the primary to the auxiliary battery when the engine runs and vice versa when it’s off.

When your engine is running, both batteries charge simultaneously. But when the isolator detects a voltage increase, it directs the charging current to the auxiliary battery. This shift ensures the auxiliary battery is charged without affecting the primary battery.

With this smart charging system, you are guaranteed a fully charged additional battery powering your accessories. You can have peace of mind knowing that you are sorted even while on extended trips or while camping in remote areas. So, how do you get started?


What Do You Need for a Dual Battery Setup?

You will need the following components to set up a 4×4 dual battery system and embrace the electrifying potential of dual batteries:

  1. Auxiliary Battery
    First, you will need an additional battery. This battery should be able to handle deep recharges and discharges. The popular choices for an auxiliary battery are Absorbent Glass Mat and Lithium batteries, known for their durability and higher energy density. However, you can also opt for the Lead Deep Cycle if you are on a budget.
  2. Battery Tray or Box
    Second, on your 4×4 dual battery setup requirement list is a battery box. A sturdy tray holds the auxiliary battery in place, protecting it from vibrations and external elements.
  3. Battery Isolator
    A voltage-sensitive relay manages the charging and discharging process of the auxiliary battery, ensuring the primary battery remains unaffected.
  4. Wiring and Cables
    You will need high-quality wiring. The cables must be able to handle the power transfer between the batteries as well as the accessories efficiently.
  5. Circuit Breakers
    Fuses and circuit breakers are designed to protect your 4×4 dual battery system safeguarding your batteries and accessories.

Where to Install a Second Battery

If you have looked at your engine and wondered where to install the auxiliary battery, pump the brakes. This section is for you. You have several options for your 4×4 dual battery setup; the most common include the engine bay, the rear cargo area and underneath the vehicle. Explore the advantages and considerations below to decide which is best for your 4×4.

  1. Engine Bay
    Installing the auxiliary battery in the engine bay simplifies the wiring process and offers you simple access in case of maintenance. However, this location demands that you consider potential interference with other engine components and take into account ventilation and protection from engine heat and vibrations.
  2. Cargo Area
    The rear cargo area protects the battery from external elements. It’s a popular choice because it also offers easy accessibility during maintenance. However, one major con to consider; the battery will occupy valuable cargo space and add weight to the rear of the vehicle, affecting your 4×4’s balance and handling.
  3. Underneath the Vehicle
    The additional battery will typically lie on the chassis or underbody, which helps free up space in the engine bay and cargo area. The battery will be protected from water or mud. However, consider potential damage from off-road obstacles and excessive heat from the exhaust system.

If you are unsure of the location of your extra battery, don’t worry. You can consult with professionals at Voltaic Auto Electrical to help you determine the optimal location based on your 4×4 and its requirements.


Maintenance of a Dual Charging System

After your 4×4 dual battery setup, Voltaic Auto Electrical professionals will help you test the system to ensure proper functionality. To keep your 4×4 dual battery system running smoothly:

  • Regularly monitor the battery’s charge level and performance to ensure your system runs smoothly.
  • Check your system for damages to the battery, DC charger, wires and battery tray.
  • Clean terminals and check connections.
