A Safe And Reliable Choice
Offering Class A and 100% Authentic Brand Cells
PRISMATIC LITHIUM CELLS: If you consider the compartment sizes for batteries, most are square. This is where the prismatic form factor comes from. These cells are available in power and energy configurations and can meet sealed lead acid battery dimensions. Despite being larger than cylindrical cells, prismatic cells pack more amp-hours per cell, thanks to more lithium by volume. They allow for larger battery pack configurations and single-cell options. Options: Due to their efficiency, they are commonly used to build larger battery packs and are a top choice for energy storage devices.
High Energy Density: Innovative Structure for Larger Capacity
Ensured Consistency: Highly automated production equipment ensures the consistency of battery cells.
Stable Voltage Platform:Low internal resistance, high discharge rate, and stable discharge voltage platform
Safe and Reliable: Lithium iron phosphate, the safest chemistry of all lithium battery types



Products are tested and certified for major markets worldwide, complying with safety, health, and environmental standards. They meet sector-specific standards in North America, Europe, Japan, Australia, and more.
