24V 300Ah Crank Battery 1500CCA Lithium Start Battery for Heavy Trucks

Our 24V lithium battery series is specially designed for heavy-duty vehicles, combining high cranking power with long-lasting energy storage. Available in 230Ah, 280Ah, 300Ah, 304Ah, and 314Ah capacities, these batteries deliver exceptional performance in both engine starting and auxiliary power applications such as truck parking air conditioners.

Built with advanced LiFePO₄ (Lithium Iron Phosphate) chemistry, these batteries are ultra-safe, maintenance-free, and highly reliable even in low-temperature environments. Compared to traditional lead-acid batteries, they offer significantly longer lifespan, faster charging, deeper discharge capabilities, and higher energy efficiency.

Each unit supports high current output (up to 1500–1800CCA), ensuring instant engine cranking power when needed, while also providing stable, continuous power for idle-free air conditioning and other onboard electronics. Whether you're operating in extreme climates or long-haul conditions, this series is engineered to deliver consistent performance and peace of mind.
