Hign Density LFP81175200 3.2V 340ah Lifepo4 Battery Cell for
Electric Vehicles and Energy Storage System
Product Description
3.2V 340Ah LiFePO4 Cell Lithium Iron Phosphate Battery Cell is the
highest capacity LFP cell we have now. It has excellent safety,
long service time, good temperature performance, high energy
density, low cost and no pollution. They are widely used in various
applications, including electric vehicles, renewable energy
storage, and portable electronics due to their stability, safety,
and long life, and provide a stable voltage output throughout their
discharge cycle, which contributes to consistent performance. It
capability of handling high discharge currents, making them
suitable for applications requiring quick bursts of power. Also
they are more environmentally friendly than other lithium-ion
chemistries, sinceit does not contain toxic metals like cobalt.
