About Us

Marine Battery Source is a Florida-based online store for boat batteries and the gear that keeps them charged. We carry marine lithium (LiFePO4), AGM and flooded lead-acid batteries for trolling motors, engine starting, dual-purpose use and house banks, along with marine chargers and installation accessories.

Batteries for every kind of boat

Kayak anglers, bass and bay boat owners, pontoon families and cruisers all need something different from a battery. Our catalog is organized the way boaters shop: by use, voltage, capacity, chemistry and brand, so you can compare options side by side and pick the right fit for your motor, electronics and budget.

Brands boaters know

We work with established marine battery brands, including Dakota Lithium, Battle Born, ECO Battery, Lithium Rhino, EPOCH, Trojan, Interstate, Bedrock and Allied.

Shipping nationwide, local service in Florida

We ship across the United States. We also install at your home, dock or marina anywhere from Venice to Gainesville, FL.
