Compared to traditional AGM/lead acid batteries, LiFePO4 batteries (Lithium iron phosphate batteries) offer several advantages:

Higher safety and stability: LiFePO4 batteries are non-toxic, non-polluting, and do not contain rare earth metals. They are not prone to explosion or fire incidents.
Long service life: LiFePO4 batteries have a lifespan that is 10 times longer than traditional batteries, making them capable of enduring 2000-4500 cycles.
Lightweight: LiFePO4 batteries are approximately 1/4th the weight of lead-acid batteries, making them a more convenient and portable option.
Wide temperature range: The LFP battery can operate effectively in a broad temperature range from -20 to +75°C, allowing for reliable performance in various environments.
No memory effect: LiFePO4 batteries do not experience a memory effect, meaning they can be charged as needed without any loss of capacity.
Versatile applications: LiFePO4 batteries are suitable for a range of applications, including use in RVs, ships, home storage systems, and telecommunication base station batteries.
