Manufacturer Part#: BB8DH

The powerful battery solution to elevate any outdoor adventure. It’s time to upgrade from your traditional lead acid battery! What you need is a new battery that’s lighter, safer, and works with various systems. More importantly, it should be able to keep you company for many of your outdoor adventures! This 270Ah 12VDC 8D LiFePO4 Deep Cycle Battery by Battle Born Batteries delivers superior and long-lasting performance!

Our lithium-ion batteries are designed for long-term use and can last up to 10 times longer than lead-acid batteries, with 3,000-5,000 deep discharge cycles. These LiFePO4 batteries also have an internal Battery Management System (BMS), which protects them from common battery failures like high and low voltage, short circuits, and hot and cold temperatures. Compared to a conventional lead acid battery, our rechargeable Battle Born Batteries are 1/5th the weight for the same amount of usable power, weighing in at just 81.4 lbs. They, too, provide up to 3x more power in the same physical space, and charge 5x faster.

With maximum safety, flexibility, and versatility, these LiFePO4 batteries can be wired in series or parallel and installed in any position, orientation, or space. Battle Born Batteries are made with quality in mind. We source our raw materials from reputable suppliers and assemble lithium batteries using cylindrical cells in our 99,000-square-foot facility in Reno, Nevada.
