Low Self-Discharge 12V 18AH Battery for Solar Energy Storage and Electric Vehicles
Product Description
Lithium iron phosphate (LiFePO4 or LFP) batteries have become increasingly popular in the marine industry due to their many advantages over traditional lead-acid batteries and even over other lithium-ion batteries. LFP batteries can be cycled for thousands of times with minimal capacity loss and they also have a higher temperature tolerance than other lithium-ion batteries. With life[po4 battery's high energy density, 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, it lifetimes of up to 20 years accroding to different usage scenario. This is because LiFePO4 batteries do not suffer from the big issues of degradation and capacity loss as lead-acid batteries, which can lose up to 20% of their capacity per year.
