Ben couldnt do enough for me, answered all my questions i had prior to purchase. I ended up ordering the slim 200ah and it didnt quite fit where i was wanting it to go so he was good enough to swap it over to the 200ah ultra slim. Excellent customer service!

THESE GUYS ARE AMAZING. Could not recommend these guys more highly. I'm not electrically minded, and Ben went above and beyond MANY times to help me understand what I was installing in my car, and how to do it. We spoke on the phone at length many times, and even spent 20 minutes on the phone with me on a Saturday to walk me through it as I was installing it.

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.

Have a 100ah Custom Lithium on my Nissan Y62 2020 Patrol to run my engel fridge..it has worked flawlessly and lasts a long time before recharging is necessary..also has a redarc bcdc charger attached for solar charging if needed..highly recommend this battery and company...excellent after sales service and warranty...

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.
