Product Description

The Camel Energy B12100P 12.8V 100Ah Marine LiFePO4 Battery is a dual-purpose lithium battery specifically engineered for marine engine starting and deep-cycle energy storage.

Unlike conventional marine batteries that are designed for either cranking or house power, the B12100P combines 800A instantaneous discharge capability with 1280Wh usable energy, allowing one battery to support both engine ignition and continuous onboard power.

Designed for fishing boats, speedboats, yachts, commercial vessels and marine service boats, the battery integrates an intelligent Battery Management System (BMS), IP67 waterproof enclosure and premium LiFePO4 cells to deliver reliable performance in harsh marine environments.

For marine OEMs, boat builders and battery distributors, Camel Energy also provides OEM/ODM customization, communication integration and private-label manufacturing services.
