The 12V immersion heated battery pack is designed for low temperature using Lithium Iron Phosphate (LFP) cells to deliver safe, stable, and reliable power for a wide range of applications. The LFP cells are immersed in a dielectric fluid, which provides uniform temperature distribution throughout the battery pack, enhancing performance and extending service life. The dielectric fluid also significantly reduces the risk of thermal runaway, ensuring superior operational safety. This battery pack features a smart BMS with active balancing and an immersion heating system for smooth operation in environments as cold as -40°C. Built for durability and safety, it is ideal for electric vehicles, solar energy systems, industrial equipment, marine applications, and backup power solutions.
