Looking for a replacement battery for a golf trolley? Want to replace the heavy lead acid battery on a mobility scooter or wheelchair? A Lithium LiFePO4 battery might be exactly what you need! But what is a Lithium LiFePO4 battery? And what is the difference between a Lithium Iron Phosphate (LiFePO4) battery versus a Sealed Lead Acid (SLA) battery? Maplin are here to help you understand the numerous benefits of using a Lithium LiFePO4 battery.

What is a Lithium LiFePO4 battery?

Lithium Iron Phosphate

A Lithium Iron Phosphate LiFePO4 battery (also known as LFP) is made up of multiple lithium cells and a battery management system (BMS). It looks and act very similar to lead acid batteries but provides a superior long-term performance with better stability.

As a type of lithium-ion battery chemistry, LiFePO4 batteries are known for having a lower energy density than conventional lithium-ion cells. This means they store less energy per unit weight or volume, but also makes them less volatile and generally safer to use. As a result, they're ideal for power tools, medical devices, emergency backup power systems and more.

Longer service life

A typical lead acid battery will run for roughly 300 – 400 cycles before it needs replacing. In comparison, an LFP battery has a long cycle life of up to 2000 cycles, making it a wise investment when it comes to keeping your electronics powered up.

They can be charged and discharged more times than conventional lithium-ion batteries before their performance begins to degrade. This makes them a great choice when longevity and reliability are key factors, such as solar power storage and backup power systems.

While the exact cycle life of LiFePO4 batteries can vary depending on factors such as temperature, charging protocols, and depth of discharge, they typically outperform other lithium-ion chemistries in terms of longevity.

Lightweight design

Unlike lead acid batteries which use heavy lead plates, glass matt barriers and liquid or gel acid, LiFePO4 batteries take up far less space and weigh significantly less!

This makes them an ideal choice when you need power on the go. We even have a specialist range of Golf Trolley batteries which make use of these lightweight Lithium LiFePO4 batteries.

Safe choice

Lithium Iron Phosphate batteries do not emit noxious gases like lead acid batteries, so they can be used safely inside living compartments. There are no heavy or toxic materials, no raw chemicals that could spill out of it and they can often run at far higher temperatures, making them a safe and responsible choice.

Unlike some other lithium-ion chemistries, LiFePO4 batteries are inherently stable and resistant to thermal runaway, making them much safer to use. This inherent stability is due to the robust chemical structure of lithium iron phosphate, which is less prone to overheating and combustion, even under extreme conditions.

This enhanced safety profile makes LiFePO4 batteries an ideal choice for applications where safety is critical, such as electric vehicles, renewable energy storage systems, and portable electronic devices.

In summary

Lithium LiFePO4 batteries represent a significant advancement in battery technology, offering enhanced safety, long cycle life, high energy density, fast charging capability, and wide operating temperature range. With their superior performance and versatility, LiFePO4 batteries are poised to revolutionize a wide range of industries, from renewable energy storage to electric transportation. As innovation continues to drive progress in battery technology, LiFePO4 batteries stand out as a beacon of reliability, efficiency, and sustainability in the quest for cleaner, greener energy solutions.
