The Great Endeavour Rally

Presenting Partner

Custom Lithium is honoured to be the Presenting Partner of the Great Endeavour Rally from 2025 through to 2027. This exciting new partnership with the Endeavour Foundation is one that we are extremely proud of, and we look forward to supporting such a meaningful cause through this incredible event.

Will we see you at an upcoming rally?

Camp For A Cure

Major Partner

Custom Lithium has proudly supported Camp for a Cure since its inception in 2024. This event, which has experienced remarkable growth, serves as a powerful call to action for businesses to join the fight against cancer.
With all funds raised benefiting the Love Your Sister Foundation, where every dollar contributes directly to the cause, Custom Lithium is leading the charge in supporting Alex and Erin, the founders of this impactful event, and stands behind it 100%.

Breast Cancer Foundation

At Custom Lithium, we are proud to support the National Breast Cancer Foundation (NBCF) through various initiatives and events throughout the year. From our involvement in the TRED 4X4 NBCF weekend at The Springs 4X4 Park, to the creation of our limited-edition Pink Batteries, each proudly displaying the Breast Cancer Foundation Ribbon, we are committed to raising awareness and supporting this vital cause.

For every Pink Battery sold, a portion of the proceeds is donated directly to the NBCF to help fund critical research. This cause is deeply personal to many of us at Custom Lithium, and we are honoured to contribute to the fight against breast cancer.

Together, we can make a difference.

Don River Dash

Naming Rights Partner

Custom Lithium is proud to be the naming rights partner for the 2025 Don River Dash. This exciting off-road race, set along the rugged riverbed in Bowen, North Queensland, pushes both riders and off-road racers to their absolute limits.

Our team at Custom Lithium shares a deep passion for off-road racing, and we are also honoured to be a Gold Sponsor of the prestigious Finke Desert Race. We are committed to supporting the off-road racing community and celebrating the spirit of adventure and endurance.

Pine Rivers Pumas Junior Rugby Union

Post Pads Sponsor

Our local community club Pine Rivers Pumas holds a special place in our hearts. Our Director, Andy, grew up in the area and played rugby for the club as a child, and now, his children are continuing that legacy by playing for the club.

Beyond sponsoring the club's post pads, we’ve also had the privilege of contributing to its local history. Custom Lithium recently donated a signed Queensland Reds jersey from the British & Irish Lions tour -a small yet meaningful piece of rugby history that will be proudly displayed in the clubhouse for all to enjoy.

K'Gari Cleanup

Platinum Sponsor

Since 2024, Custom Lithium has been leading the way in supporting the K’Gari Cleanup as a Platinum Sponsor. With K’Gari right on our doorstep in Brisbane, we’re fortunate to visit this stunning island multiple times each year.

Our commitment to this incredible initiative is our way of ensuring the island’s beauty is preserved for future generations to enjoy.

MOR Motorsport

Major Sponsor

Jack and Amy from MOR Motorsport were the driving force that introduced our team to the world of off-road racing. Their trophy ute, designed for exceptional speed across the toughest terrain in Australia, is a true testament to their skill and style.

After attending the Finke Desert Race for a couple of years, our team had the privilege of supporting MOR Motorsport at the Don River Dash in 2024. Following this, we were honoured to become the naming rights sponsor for the event.

We take great pride in seeing the green and gold car race through each challenge, representing the strength and resilience of off-road racing.

Cody Brewczynski

Major Sponsor

Cody,along with his dad Adam, and the team at Western Sydney Motorsport compete in the V8 Superutes category across Australia, and Custom Lithium is proud to support Cody in achieving his racing goals. What began as a business partnership has evolved into something much more, becoming a vital part of our extended family.

Andy and Kirsty make it a point to attend the events, offering their support to Cody while fostering the growth of both his racing career and our business. The shared passion for motorsport and the drive to constantly improve is what fuels this partnership, and it's what motivates us all to push forward each day.
