The Weight Savings of Lithium Batteries for Caravans and Motorhomes

Home / Batteries / The Weight Savings of Lithium Batteries for Caravans and Motorhomes

Weight Saving When Needed

One major advantage of upgrading to lithium iron phosphate batteries in your caravan or motorhome is significant weight reduction. Lithium leisure batteries weigh around 50% less than an equivalent lead-acid battery.

    • Easier Handling and Installation
    • Improved Payload Capacity
    • Enhanced Fuel Efficiency
    • Fewer Total Batteries

For example, a 100Ah lithium battery comes in at just 11-13kg. A comparable 100Ah lead-acid battery tips the scales at over 25kg.

That large weight difference provides some key benefits:

Easier Handling and Installation

At half the mass of lead-acid batteries, lithium batteries are much easier to maneuver into place and connect up during installation. The reduced size and bulk also provides more positioning options inside your motorhome or caravan.

Improved Payload Capacity

Removing over 10kg from your battery installation gives you back precious payload capacity for other gear and supplies. Lighter lithium batteries allow you to carry more equipment and consumables for your motorhome adventures.

Enhanced Fuel Efficiency

Lower vehicle weight equals improved fuel economy. By reducing your motorhome or caravan’s mass, lithium batteries will incrementally reduce your petrol or diesel consumption over time. That saves money at the bowser.

Fewer Total Batteries

Thanks to the 10x longer lifespan of lithium technology, you can use fewer total batteries over the ownership period of your motorhome or caravan. Going from 4 lead-acid batteries down to 2 lithium batteries results in a big weight decrease.

In summary, lithium leisure batteries weigh around 50% less than lead-acid equivalents. That significant weight saving provides easier installation, increased payload capacity, improved fuel efficiency and reduced overall battery bank weight over time. Lighter lithium batteries help maximize the capabilities of your caravan or motorhome.
