  • What are the advantages of prismatic LiFePO4 batteries over cylindrical cells?

    Prismatic cells offer higher energy density within a compact rectangular design, making them ideal for space-constrained applications. They provide better heat dissipation due to larger surface area, enhanced structural stability, and simpler integration into battery packs. Compared to cylindrical cells, prismatic designs also reduce internal resistance for improved efficiency and support more flexible terminal placement for easier installation.

  • Are these batteries compatible with existing 12V systems designed for lead-acid?

    Yes. Our 12V prismatic LiFePO4 batteries are designed as drop-in replacements for lead-acid batteries (AGM/gel/flooded). They feature standardized terminal layouts (e.g., M8 threads), compatible voltage profiles (12.8V nominal), and built-in BMS to ensure seamless integration with automotive, solar, or marine systems without requiring additional components or modifications.

  • What applications are best suited for 12V prismatic LiFePO4 batteries?

    Their compact size and high reliability make them ideal for:

    Solar energy storage: Off-grid and hybrid systems.

    Marine/RV: Powering electronics, lighting, and auxiliary systems.

    UPS/Backup power: Critical backup for servers and medical devices.

    Electric mobility: Golf carts, scooters, and mobility chairs.
