I went to purchase a 200amp lithium battery from Ben. As far as price and warranty, these guys were up there with the major brands if not better. Battery is amazing and kept my 50lt Waeco running for 9 days no charge. Happy if anyone wants info or recomendations.

Ben and 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.

Their customer service is incredible. We had so many questions during the quoting process; we sent so many messages that were answered promptly and in a very helpful manner. It extends beyond that though, during the install we dropped into the workshop to watch some of the process- the welcomed us with open arms and took their time to show us everything. We will 100% be back for our caravan upgrade!

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.

I cannot recommend this company highly enough, if I could give them 10 / 5 stars I would. After ordering a battery and receiving the battery I realised I made a mistake on what terminals I wanted. After a quick back and forth with the legends at custom lithium I shipped it back to them, they made the changes and expressed it back down to me.
