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 an LiFePO4 battery? And what is the difference between a Lithium Iron Phosphate (LiFePO4) battery versus a Sealed Lead Acid (SLA) 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.

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!

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.
