Excellent battery, company, and customer service!

I live in my camper full time and needed to upgrade to LiFePO4. After extensive research I found Premium Lithium offered the best value and most promising product. The battery has performed exemplarily. You’ll do no better than choosing these guys.

I bought 2 LiFePO4 batteries

They have performed really well over the last year with Nick and Matthew providing excellent support and advice before during and after purchase. A recent problem with 1 battery was sorted for me by Nick whilst I waited. I wouldn’t hesitate to recommend them.

LiFePO4 battery experience

I bought a LiFePO4 battery for my off grid solar system. I've never had a battery perform as well as this one and it's impressed me so much I've bought another. They are extremely helpful making sure you're getting the most out of their products. I'd highly recommend them.

A genuine trustworthy company

I first discovered Premium Lithium through eBay, searching for the best available products at a competitive price. Matthew was a great help, happy to answer any questions. I ordered 4 lithium batteries, which arrived promptly, exactly as described and very high quality.
