LiFePO4 Marine Battery: What You Should Know

Author: Polinovel | June 29, 2022

Overview

More and more people are switching to LiFePO4 marine batteries. Do you know why they prefer LiFePO4 batteries?

Let’s take a closer look at the reasons why people choose LiFePO4 marine batteries instead of lead-acid batteries.

Part 1. Why Do People Choose LiFePO4 Marine Batteries?

LFP batteries are an excellent choice for marine applications due to the unparalleled advantages they have.

Light Weight

We should know that every boat has a weight limit, and reducing the weight on the boat is quite important. LFP batteries are about 1/3 the weight of lead-acid batteries, which can boost the boat’s speed.

Low Self-discharge Rate

LFP batteries have a lower self-discharge rate compared to lead-acid batteries. Lead-acid batteries can lose power when not being used. If you rarely use your boat, it will take a long time to charge before you head out for sailing. Conversely, LFP batteries can retain most of the power and have a self-discharge rate of less than 3% per month.

Long Lifespan

LFP batteries can last about 5,000 cycles. Lead-acid batteries, on the other hand, can only reach about 500 cycles. We can see that LFP batteries last much longer than lead-acid batteries. Under normal use, LFP marine batteries can be used for 10 years or more.

Money-Saving In The Long Term

Though purchasing an LFP battery will cost more money upfront than a lead-acid battery, it is a more cost-effective investment in the long run. LFP batteries have the advantages of light weight, a low self-discharge rate, a long lifespan, etc. However, lead-acid batteries have a shorter lifespan and require much maintenance. If you use lead-acid batteries, you will spend much money maintaining or replacing them.

Part 2. Are LiFePO4 Batteries Safe to Use in Marine Applications?

Yes, LiFePO4 batteries are safe to use. Most LiFePO4 batteries are designed with an internal battery management system, which can monitor and control the batteries to avoid damage. What’s more, LiFePO4 batteries feature great structural stability. They will not explode even if they are exposed to severe temperatures or hazardous events.

Summary

Using LFP batteries in the marine application is worth it due to their benefits of large weight reduction, a low self-discharge rate, a long lifespan, etc.
