Marsen Energy was officially founded on 1 July 2016, but the journey began several years earlier while researching an off-grid power system for our own property in regional Western Australia.

At the time, lithium battery technology was still relatively new to the Australian consumer market. What began as a search for the right energy storage solution quickly developed into a fascination with the technology itself. Countless hours were spent researching lithium batteries, battery management systems and the rapidly evolving energy storage industry.

During that research, one thing became clear: demand for lithium battery technology was growing rapidly, yet very little battery manufacturing was taking place in Australia.

That discovery laid the foundation for Marsen Energy.

Marsen Energy designs and assembles custom lithium-ion battery packs in-house in Western Australia. We also supply lithium-ion cells, battery-building consumables and related hardware.

From one-off replacement batteries and prototypes through to ongoing production requirements, we work closely with our customers to develop practical, reliable battery solutions.

Marsen Energy supplies products and solutions to customers working across defence, robotics, autonomous systems, drone technology, personal electric vehicles, research and other advanced technology sectors where reliability, safety and performance are important.

Many of the projects we contribute to remain confidential, but our customers rely on us for quality components, practical technical expertise and dependable support throughout the life of their projects.

Marsen Energy is proud to be the authorised supplier of Molicel lithium-ion cells in Australia.

Our relationship with Molicel goes beyond supplying their products. We have spent time with the Molicel team in Taiwan, including visiting their manufacturing facilities and gaining a deeper understanding of the technology, quality standards and processes behind their lithium-ion cells.

Molicel has also visited Australia, where we were proud to introduce their team to a number of our customers in Western Australia and the Eastern States.

By sourcing through authorised channels and maintaining a close relationship with the manufacturer, our customers can purchase genuine Molicel products with the confidence of local support and technical expertise.

Marsen Energy continues to grow alongside the technologies and industries we support.

Alongside our lithium-ion cells, battery-building hardware and custom battery solutions, we are preparing to introduce a range of Australian assembled compatible replacement power tool batteries, built with the same focus on quality, safety and dependable local support.

As technology evolves, so will we. Our mission remains the same as it was in 2016: to provide high-quality battery products, practical expertise and dependable service while helping Australian businesses, engineers and enthusiasts turn their ideas into working solutions.

Thank you for being part of the Marsen Energy journey.
