Lithium Extension Batteries

Lithium Extension Batteries have revolutionized the camping experience by providing reliable power sources for campervans. But what exactly are these batteries, and how do they work? Let's dive into a technical explanation of Lithium Extension Batteries in campervans.

What are Lithium Extension Batteries?

Lithium Extension Batteries, also known as auxiliary batteries or secondary batteries, are additional power units installed in campervans to supplement the vehicle's primary battery. These batteries are primarily designed to power onboard accessories and appliances such as lights, refrigerators, heaters, and other electronics without draining the campervan's main (starter) battery and can be easily added to any traditional Lead Acid charging system.

The term 'Lithium' in Lithium Extension Batteries refers to the type of technology used in these batteries, which is Lithium-ion. Lithium-ion batteries are known for their lightweight properties, high energy density, and ability to recharge quickly and efficiently compared to traditional lead-acid batteries.

How Do Lithium Extension Batteries Work in Campervans?

In a campervan setup, the Lithium Extension Battery is connected to the vehicle's electrical system. When the campervan's engine is running, the vehicle's alternator charges both the primary and the extension battery. Some campervans also feature solar panels for an additional or alternative charging method.

Once the engine is turned off, the power to the accessories and appliances is drawn from the Lithium Extension Battery, preserving the main battery's charge for essential functions, such as starting the engine. This setup allows campers to use electrical appliances even when the vehicle is stationary for extended periods.
