LFP52148102 Stable and Durable 3.2V 87ah Lifepo4 Battery Cell for Electric Power System
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.
It batteries also have a relatively low cost of ownership, as they require less maintenance and replacement than traditional lead-acid batteries. They also have a low self-discharge rate, meaning that they can hold a charge for longer periods of time without losing capacity. This makes them ideal for applications where the battery is not frequently used, such as in solar energy systems or backup power systems.
