12v 500ah Lithium Ion Battery

Our marine lithium batteries are designed to deliver reliable power during your long trips on open water. Our 36V & 51.2V marine lithium battery packs deliver Power You Can Depend On for long open water trips. Many manufacturers and boat owners have moved from flooded lead-acid batteries to sealed AGM (Absorbed Glass Mat) for their zero maintenance and mounting flexibilities. However, upgrading to LiFePO4 battery technology offers these advantages — and much more, including:

● Stronger & better performing – A difference you can feel!

● Durable & Longer Life – Saves you Money!

● Dependable & Versatile – No Hassle!

● Safe & Green – Good for you… and the environment!

Why choose BSLBATT for my Marine System?

Our battery delivers higher peak and continuous discharge currents than ordinary lithium-iron phosphate batteries of the same size, giving you class-leading power in a compact form factor. Cutting-edge engineering from the undisputed leader in boating produces a top-tier BSLBATT marine battery that weighs up to 50% less than imitators’ models, for greater fuel efficiency, faster speeds, and better draft, all with no water maintenance. Power regulation delivers full power over the full discharge—no more puttering along as the battery slowly fades. Our BSLBATT Lithium Battery adds a faster charge rate and slower dormant discharge rate, with the safest, most cost-effective form of lithium technology on the market. 5-year warranty if purchased aftermarket or BSLBATT lithium marine battery dealers.
