A dual battery system is a vehicle battery system that uses a secondary battery in addition to the vehicle’s main starter battery. The main starter battery is responsible for starting the engine and powering the vehicle’s essential electrical systems when the engine is running.
Featuring two sets of terminals, a dual post battery accommodates standard automotive connections and auxiliary accessories like winches or sound systems. This allows additional devices to draw power directly without affecting critical functions, ensuring seamless operation for your vehicle’s varied electrical demands.
This dual system provides ample advantages, especially in scenarios that demand more electrical power than a single battery can supply. In vehicles that are designed or modified to carry out heavy-duty tasks, or ones that are equipped with a plethora of electrical accessories, a secondary battery becomes essential.
Among all available candidates, dual-ion batteries (DIBs) have drawn tremendous attention in the past few years from both academic and industrial battery communities because of their fascinating advantages of high working voltage, excellent safety, and environmental friendliness.
When installing dual batteries, it’s essential to pair the positive terminal of the primary battery with the negative terminal of the secondary battery. This arrangement is known as a series connection, which is crucial for a 24V system.
Many tradies use their dual battery system to charge their power tools whilst on the worksite and it’s a great way to keep the kids devices charged too. A dual battery system allows you to run auxiliary equipment without draining the main starter battery.
