Our Story

Founded in Brisbane, Queensland, Custom Lithium is a proudly Australian family-owned business specialising in ultra-compact, high-capacity lithium batteries for caravans, 4WDs, and commercial and industrial applications. Our batteries are built to endure the harshest Australian conditions - delivering the reliability, efficiency and performance that Australian adventurers and industries demand.

Andy & Kirsty run Custom Lithium with a simple belief: that Australian-made products, backed by people who genuinely care, will always outperform the alternative. That belief hasn't changed. What has changed is the size of the community we're now proud to be part of.

At Custom Lithium, we're more than a business - we're a family operation that happens to make world-class batteries. Our commitment to our team, our customers, and the communities we're part of sits at the heart of every decision we make. The partnerships and sponsorships we take on aren't driven by marketing budgets or brand exposure targets. They're driven by genuine connection - to people, to causes, and to the Australian spirit of backing those who give everything they've got.

Andy and Kirsty are hands-on in everything - including showing up. You'll find them trackside at motorsport events, on the ground at community days, and present at every partnership we're proud to carry our name into. That's not a PR strategy. That's just who we are.

When you choose Custom Lithium, you're investing in a product that's genuinely built to perform. But you're also supporting a family business that puts community first - one partnership, one sponsorship, one adventure at a time.

Here's some of what we're proud to be part of...

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%.

Don River Dash

Naming Rights Partner

Custom Lithium is proud to be the naming rights partner for the 2025 & 2026 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.

Finke - 50th Anniversary

Gold Sponsor

The Finke Desert Race is not just a race. It's a living piece of Australian motorsport history - and in 2026, it turns 50.

Custom Lithium is proud to be a Gold Sponsor of the 50th Anniversary Finke Desert Race, one of the most gruelling and iconic off-road events on the planet. From Alice Springs to the remote community of Aputula and back - over 460 kilometres of raw, unforgiving outback terrain that tests man, machine and every component in between.

Being part of this milestone year means everything to us.

And this year, we're not just on the banner. Custom Lithium will be on the ground at Finke, unveiling our purpose-built off-road Can-Am Maverick R - engineered for exactly this kind of terrain and built to show what Australian-made performance looks like when it has nowhere to hide.

Fifty years of Finke. We're honoured to be part of it.

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.

Cody Brewczynski

Custom Lithium Racing Athlete

What started as a business partnership is now in its second year - and in 2026, we're taking it to a whole new level.

Custom Lithium is proud to back Cody Brewczynski as the naming rights partner of his #22 Trans Am Ford Mustang, competing in the Trans Am Series across Australia - televised live on Kayo Sports and Fox Sports.

Cody's relentless drive, precision behind the wheel and refusal to settle for anything less than his best reflects everything we stand for as a brand. Andy and Kirsty continue to support Cody trackside, and what began as a shared passion for motorsport has grown into something that genuinely feels like family.

This is year two. The car is faster, the stage is bigger, and the whole country is watching. We couldn't be prouder to have Cody carrying the Custom Lithium name.
