Stable LFP20100140 3.2V 30ah Lifepo4 Battery Cell for Electric Bicycle and Scooter and Solar Energy Storage Syatem
Product Description
Lithium Iron Phosphate (LiFePO4) batteries are a type of lithium-ion battery known for their stability, high safety, and long cycle life. They are widely used in various applications, including electric vehicles, electric scooters, electric power system, renewable energy storage, and portable electronics and provide a stable voltage output. It is capable of handling high discharge currents, making them suitable for applications that requiring quick bursts of power. LFP batteries are more environmentally friendly than other lithium-ion chemistries, it does not contain toxic metals like cobalt.
LiFePO4 batteries also have a relatively low cost of ownership, as they require less maintenance and replacement than traditional lead-acid batteries. Also tthey have a low self-discharge rate, it means that they can hold a charge for longer periods of time without losing capacity. All these features makes them ideal for applications where the battery is not frequently used, such as in solar energy systems or backup power systems.
