About Lithium Battery Supply

Your online reseller for premium lithium batteries, chargers, and accessories sourced from trusted U.S.-based manufacturers and shipped directly to your door.

Who We Are

Lithium Battery Supply is an online retailer operating under active reseller agreements with established U.S. battery manufacturers. We are not a manufacturer, we are a reseller that connects customers with certified lithium battery products from Epoch Batteries, Dakota Lithium, BigBattery, Allied Battery, and Bolt Energy.

We operate entirely online, serving customers throughout the 48 contiguous United States. All orders are fulfilled by our manufacturer and distributor partners and shipped directly to you from their U.S. warehouses. We do not hold physical inventory.

Our dealer credentials are on file with each manufacturer we carry. As these brands update their dealer directories, our listing will appear on their official websites.

Our role is to make it easy and reliable for you to purchase the right lithium battery solution handling the ordering process, product guidance, and post-purchase support on your behalf.

Our Mission

We exist to help customers confidently transition from traditional lead-acid batteries to modern lithium technology. Whether you're outfitting an RV, marine vessel, golf cart, or industrial application or building an off-grid or home energy storage system, we guide you through selecting the right battery for your specific needs. If your goal is energy storage, we'll help you find the right capacity, voltage, and chemistry to power your setup reliably and efficiently.

Our goal is to be a reliable, transparent destination where every customer feels informed and supported from first inquiry through to delivery and beyond.

How We Operate

When you place an order, it is fulfilled and shipped directly from our manufacturer or distributor partner's U.S. warehouse to your address, the same fulfillment model used by major retailers.
