Dual Battery Systems
June 1, 2022
There are many types and methods to utilize a second battery and how to charge them. Camping installations, 4WD or Trade utilitie orientated DC/DC power needs are similar in the way products are selected and installed.
The first decision that needs to be focused on, is, what will be the power demands of your best thoughts, wants and needs. Some travellers will require a microwave oven where others may only need to run a small fridge/freezer. Tradies may want to charge their battery-operated tools or run electric tools.
The battery size and chemistry are very important as not having enough power will defeat the point of the setup to begin with. Do we require, only one 100AH battery or do we need a larger capacity? Amp Hour capacity will depend on your requirements, which will determine 1 or 2 auxillary batteries which will also depend on the size and space you wish to fit them. Once the decision has been made, the batteries need to be kept charged at the most optimal way. This brings into question how we drive the vehicle. If very short trips are driven, for example 20 minutes, followed by a long stay of over 8 hours using battery power, a DC/DC charger may not be the best way to charge your storage batteries. A solar setup, whether it be a solar blanket or fixed panels may be a better solution. If, on the other hand, long 5 hours plus drives are planned, followed by overnight only stays between drives, a DC/DC charging system will be the most practical option. Early model vehicles without a smart charger, can simply have a VRS “Voltage sensitive relay” installed between the starting battery and the storage batteries, making it a very inexpensive addition to your rig.
Should you have a late model, you may have a “smart alternator”, which requires the intervention of a DC/DC unit to assist the Alternator to recognize the send storage battery to send a charge to it. Either way, knowing your batteries carry a full charge after a long drive is reassuring. Most of the mid-range products will have Lithium and solar recognition, making it even easier to create your own custom requirement for your storage battery charging comfort.
It is a very tailor-made option as what is best and speaking to your battery specialist is always best practice. 20 Amp- 40Amp DC/DC chargers for AGM batteries and anything over 40Amp to 60Amp for Lithium batteries could be required for the best results for charging while driving. Battery case size often is a factor depending on space available, and for very tight installations, Slimline batteries have their place in modern tightly packed situations, i.e. you can fit them behind the back seat of twin cab utilities.
Your choices are many and your battery specialist has seen and installed many configurations. Call in store to get advice, see the products in your hand and let us help you design a system that works for you

Power Camping and 4x4 is committed to providing comprehensive and professional service to our customers. With the ever-evolving technology in modern cars, ensuring the correct car battery configuration is essential for optimal performance and longevity. Gone are the days when replacing a battery was a simple swap-out procedure. Modern vehicles are equipped with sophisticated CO2 production control systems, such as smart charging and Idle Start Stop (ISS), which demand precise battery configurations and registration with onboard computer systems. Car Battery Replacement Experts Power Camping and 4x4 uses the best diagnostic tools to ensure your car battery replacement is done right, every time. Failure to adhere to these specifications can lead to a cascade of issues, none of which are covered by the manufacturer's warranty. Potential consequences of neglecting proper battery configuration: Undercharging or Overcharging: Incorrect battery parameters can lead to undercharging or overcharging, both of which can damage the battery irreversibly. This damage isn't covered by warranties, leaving vehicle owners with unexpected repair costs. Loss of ISS Functionality: Particularly the Idle Start Stop system, designed to reduce emissions and improve fuel efficiency, relies on precise battery parameters. Failure to configure the battery correctly may result in the loss of this functionality, impacting both environmental performance and fuel consumption. Loss of Non-Critical Vehicle Systems: Many modern cars rely on intricate electronic systems for various functions. Improper battery fitment and configuration can disrupt these systems, leading to malfunctions or failures that compromise the overall driving experience. Our highly trained, local Battery Experts at Power Camping and 4x4 use the best-in-class diagnostic tools and the right battery every time. The BT608 battery diagnostic tool is a great example of what Battery Traders uses. It is a leading-edge solution designed to streamline the configuration process for vehicles equipped with smart charge and ISS systems. This tool plays a pivotal role in ensuring: The vehicle recognises the installation of a new car battery. The charging system adjusts to accommodate the new battery's characteristics. The vehicle utilises the correct charging parameters tailored to the new battery. The BT608 isn't just a configuration tool; it's a comprehensive diagnostic powerhouse. From testing 6 & 12V batteries using adaptive conductance to analysing 12 & 24V charging/cranking systems and even reading and erasing basic non-critical error codes, this tool offers unparalleled versatility and functionality and is best practice. If you need a new car battery for an ISS Stop Start or smart-charge car battery replacement, ask what diagnostic tools they use. Unfortunately, some car battery shops will fit what they have and hope for the best. By being informed about the advanced tools and techniques employed during the installation process, your vehicle and battery will last longer and not cause any unintended consequences. In today's fast-paced automotive landscape, staying abreast of technological advancements isn't just our promise; it's a necessity. With the BT608 and highly trained battery technicians, your car battery replacement is assured, warrantied, and registered. Choose the best car battery replacement, choose Power Camping and 4x4 with the best battery prices.
