LiFePO4 Battery


Safety is always our first consideration when we choose batteries. At present, lithium iron phosphate batteries are becoming more and more popular. Are the batteries safe?

In this article, we will talk about the safety of lithium iron phosphate batteries.

Part 1. Safety of LiFePO4 Batteries

Lithium iron phosphate batteries, also known as LiFePO4 and LFP batteries, have high safety. We’ll talk about why they are safe in this part.

First, the phosphate-oxide bond in LiFePO4 batteries is stable. When the LiFePO4 batteries are overcharged, the phosphate-oxide bond will not break down and generate excessive heat.

What’s more, the lithium iron phosphate cells are non-combustible. They can also withstand harsh conditions, such as freezing cold or scorching heat.

More importantly, LiFePO4 batteries have a built-in battery management system. The BMS can monitor, manage the batteries, and keep them away from over-charge, over-current, short-circuit, etc.

Part 2. Benefits of LiFePO4 Batteries

Besides high safety, LFP batteries have many other unparalleled advantages.

Light Weight

The weight of the lithium iron phosphate batteries is about 2/3 of that of lead-acid batteries. LiFePO4 batteries are lightweight while delivering high energy density.

Low Self-discharge Rate

LiFePO4 batteries have a low self-discharge rate of less than 3% per month. LiFePO4 batteries can be left standing for months without causing damage.

Fast Charging

LiFePO4 batteries have a high charging rate. They charge much quicker than lead-acid batteries. Fast charging reduces the batteries’ downtime and improves efficiency.

Long Life

LiFePO4 batteries can last 5,000 cycles at 80% depth of discharge, without affecting the performance.

What’s more, LiFePO4 batteries require minimal maintenance and infrequent replacement. They are an ideal investment in many applications, such as solar energy storage systems, boats, golf carts, etc.


Compared to lead-acid batteries, LiFePO4 batteries offer significant advantages, such as high safety, low self-discharge rate, a long lifespan, etc. LiFePO4 batteries are a worthwhile investment for us.
