The Benefits of Lithium Iron Phosphate Batteries (LiFePO4)

Nowadays, lead-acid batteries make use of a combination of materials like sulfuric acid and lead plates. In 1859, this was the first kind of battery that could be recharged. On the other hand, lithium-ion ones are a new invention. Their commercial production began in the 1980s. given below are some of the primary benefits of LiFePO4 batteries. Read on to find out more.

1. No Voltage Sag

As far as lithium batteries are concerned, their discharge curve is flat. This means that if you have a 20% charged unit, you will get the same degree of output from it as a unit that is 80% charged.

And this can prevent a lot of issues due to “voltage sag”. Also, there is almost zero percent voltage loss. In other words, lithium-ion units can provide all of the rated capacity at high current rates. On the other hand, lead-acid ones may lose up to 40% of the capacity if you put a lot of load on these units.

2. Longer Life Cycle

If you get a high-quality LiFePO4 unit, you may get thousands of cycles from the product. In real life, they can offer up to 2000 cycles considering an 80% depth of discharge at a 1C rate of discharge. And the rest of the capacity stays over 80%. It’s important to keep in mind that these values depend upon the rate of discharge and the product quality.

Also, these charge cycles are higher than NCA or NMC. On the other hand, if you get the best lead-acid products, you won’t be able to get more than 1000 cycles.

3. Optimum Capacity

Unlike a lead-acid unit, LiFePO4 ones allow you to use up to 90% of the rated capacity. In some cases, the capacity is even higher. For instance, if there is a 100 amp-hour unit, you can get up to 90 amps out of it without a problem.

4. Easy to Maintain

Easy maintenance is another advantage of these units. The balancing system ensures that all of the battery cells are fully charged. All you need to do is charge the unit and you will be good to go for hours.

5. Efficient Charging

The good thing is that lithium-ion batteries allow you fast charge them to their full capacity. On the other hand, the lead-acid ones have an absorption phase if you want to get the 20% stored. Also, if you use a powerful charger, you can charge these units much faster. In fact, you can charge your unit in just 30 minutes.

6. No Power Wastage

From the efficiency point of view, lead-acid batteries take ages to store power. Lithium units charge at around 100% efficiency unlike the 85% efficiency offered by the majority of lead-acid ones. This is true if you are going to charge the units using a solar system.

In short, these are just some of the main benefits of LiFePO4 batteries in the here and now. Hopefully, you will be able to get the most out of these units.
