High Energy.
High Power. One chemistry.
Rechargeable lithium-iron-phosphate cylindrical cells in two product lines — High Energy LiFePO₄ for runtime-driven applications, and High Power LiFePO₄ for high-current loads. Twenty standard models across nine diameters, backed by a 5-year guarantee, engineered for safety, thermal stability, and long calendar life.
Built to last.
Built to be safe.
LiFePO₄ trades a portion of energy density for what most industrial and stationary applications actually need — long calendar life, thermal stability across operating ranges, and a chemistry resistant to thermal runaway. Backed by a 5-year product guarantee.
Up to 2,000 full charge cycles at standard test conditions — multiple times the cycle life of comparable NMC cells, making LiFePO₄ the chemistry of choice for stationary, industrial, and high-duty-cycle applications.
Manufacturer guarantee covers performance and safety for five years from delivery — supported by full UN 38.3, IEC, and UL test data for procurement and certification programs.
LiFePO₄ cathodes remain stable at high operating temperatures where NMC chemistry degrades — making the cells suitable for engine bay, attic, telecom shelter, and outdoor industrial deployments.
LiFePO₄ chemistry passes overcharge, nail penetration, crush, and short-circuit testing without fire or explosion. The cobalt-free, nickel-free formulation is the chemistry of choice when safety drives spec.
20 SKUs across
nine diameters.
