Rechargeable LFP2265146 3.2V 21ah Lifepo4 Battery Cell for Electric Bicycle and Scooter

Product Description

Lithium iron phosphate (LiFePO4) batteries, also known as LFP batteries, are a type of lithium-ion battery that have gained popularity in recent years due to their numerous advantages over traditional lead-acid batteries.

The main advantages of LiFePO4 batteries is their high energy density. This means that they can store a large amount of energy in a relatively small package, making them ideal for applications where space is limited. They also have a longer lifespan than traditional lead-acid batteries, with some manufacturers claiming lifetimes of up to 20 years. This is because LiFePO4 batteries do not suffer from the same issues of degradation and capacity loss as lead-acid batteries, which can lose up to 20% of their capacity per year.
