Stable and Durable 3.2V 52ah LFP28148115 Lifepo4 Battery Cell for Electric Vehicles
Product Description
Lithium Iron Phosphate (LiFePO4) batteries are a type of
lithium-ion battery known for their stability, safety, and long
life. They are widely used in various applications, including
electric vehicles, renewable energy storage, and portable
electronics 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.
