"Great service and fantastic product"

Just picked up my 200ah ultra slimline battery, great service and fantastic product. They had some supply issues and kept me informed and managed it well.

"Those batteries never skip a beat."

Custom Lithium team is just simply amazing! Their Customer service is probably the best I've come across in years, and I do deal with a lot of suppliers being a 12V business owner.

Prompt response even at late hours and the quality of their products is just the best in OZ. Built tough to last too! Those batteries never skip a beat. Those are the only lithium batteries I recommend to my customers. Custom Lithium all day every day!

"Couldn't be Happier"

The guys did a huge effort to get our custom battery and setup done. They captured everything we wanted to achieve on our setup and we couldn't be happier. Would highly recommend.

"Excellent service & technical advice"

Helped me select a battery that suited my requirements and quickly responded to messages when I asked for advice on installation and trouble shooting after my purchase. Battery has performed well since being installed.

"Excellent product & outstanding service"

Andrew at Custom Lithium went above and beyond when setting up the power system in my van. A 400Ah Lithium battery custom made to fit where I needed it, and the necessary peripherals all set up to run my fridge, fan, tv, lights and more. Couldn't be happier with their excellent product and outstanding service.
