5 Reasons why LiFePO4 Battery is suitable for Marine Boats

As individuals own more and more wealth, more and more people will choose to buy marine boats. There are many benefits to buying a marine boat, such as ease of travel and the ability to immerse yourself more in your vacation. Sailing can be more fun if more appliances are available. At present, there are basically two types of marine batteries, lead-acid battery, and LiFePO4 battery, but there is no doubt that the LiFePO4 battery is better in general.

The excellence of the LiFePO4 battery is not to brag. It does have many benefits when used in the marine battery.

The Benefits of LiFePO4 Battery as Marine Battery?

1. Lightweight 

This is a very important factor. When a marine boat is sailing at sea, it will be greatly affected by the counterweight. Overly heavy batteries undoubtedly put a great burden on the marine boat, and to some extent increase the risk of hitting rocks and sinking.

LiFePO4 batteries have a lighter weight, and under the same energy, LiFePO4 batteries can even be about twice as light as lead-acid batteries. Therefore, in terms of the weight of the marine battery, the LiFePO4 battery is the absolute winner.

2. Better Security

Once you’re out sailing, for the most part, you can only rely on yourself. So safety is very important. In the vast ocean, once there is a problem with the ship’s fire, your ship is likely to be scrapped directly, and the time waiting for rescue at sea will crash you.

The LiFePO4 battery safety is very good. High-quality LiFePO4 batteries (how to judge the quality of LiFePO4 battery?) Even if they are punctured or collided with force, they will not explode, and they can only emit smoke to the greatest extent. This is due to the chemistry and internal structure of LiFePO4 batteries. And the excellent safety is very superior to the relatively isolated maritime environment, you can ensure the safety of your marine ship, and you can ensure your personal safety.

3. Long Life

The period of sailing can be very long or very short. Some people make a living by sailing, while others just sail on their vacation. But in general, LiFePO4 batteries with longer life will be more popular.

As a marine battery, the LiFePO4 battery can provide more than 5000 cycles and a lifespan of up to 10 years. This is unmatched by lead-acid batteries. And, if used properly, the chance of LiFePO4 battery damage will be very low, which means that the LiFePO4 battery will last longer.

4. Support High-speed Charging and Discharging

This is also a very important factor. Although for boat owners who have PV panels installed, it’s not that much of a feature to brag about. But it is very important for shipowners who need to dock to replenish power. Fast charging and discharging means that curb work can be done in a fraction of the time. According to the size of the battery capacity, the LiFePO4 battery can generally be fully charged within 3-7 hours.

5. Large Capacity

When you go out to sail, perfect electrical equipment can definitely bring you an unprecedented sense of security and convenience. Whether it’s a coffee machine or a computer, a refrigerator, or an air conditioner, as long as your marine battery still has power redundancy, you can always enjoy the fun and convenience they bring to you.

LiFePO4 batteries have a much higher energy density than lead-acid batteries, which means that under the same weight, LiFePO4 batteries can have more usable capacity, which means you can use more appliances and run longer.

However, it should be noted that to use a LiFePO4 battery as a marine battery, it is necessary to pay attention to certain waterproof treatments, after all, the marine environment is complex. Batteries are a type of power source, and exposing them to seawater-filled environments will often disappoint you.


It is the most sensible choice to use a LiFePO4 battery as a marine battery. Although the LiFePO4 battery is not the cheapest or the best performance, in general, the LiFePO4 battery meets most of the needs of sailing, and the price for long-term use is very reasonable, it’s not without reason that it’s called the most nautical battery.
