right solution for lithium ion marine batteries

Replacing marine batteries with LiFePO4 batteries can improve the service life, safety, and stability of the battery while reducing maintenance costs and environmental impact.

Your Ideal Lithium Deep Cycle Lithium Ion Marine Battery

Due to its unique advantages, lithium ion marine batteries are becoming increasingly popular in the boating industry.  LiFePO4 batteries are lightweight, compact, and have a high energy density ratio, making them ideal for use in marine environments. They last longer and require less maintenance than traditional lead-acid batteries.

The main advantage of LiFePO4 batteries is their ability to store more energy in a smaller space. More suitable for small boats with limited space, or larger boats where weight distribution is critical. And they are also highly efficient, they can charge faster and hold their charge for longer periods of time.

Lithium ion marine batteries are also more environmentally friendly than traditional lead-acid batteries. They are non-toxic and produce less waste, which can lead to a cleaner and more environmentally friendly world.

In short, the upgrade of lithium-ion marine batteries is a trend that is coming of age for boaters. They can provide longer life, higher energy density, and are more environmentally friendly than traditional lead-acid batteries, with a self-discharge rate of less than 3% and greater durability. With these benefits, it’s easy to see why more and more boaters are turning to lithium ion technology.

Deep cycle Lithium ion marine battery

Lithium ion deep cycle marine batteries have a different performance from lead-acid batteries. When you want to have fun and say go on a sea trip or sailing, no need to worry about the battery charging too slowly or the battery consumption being too fast. Or the battery life is too short. With high efficiency, lightweight, and easy maintenance of lithium ion marine battery, you can do more of what you like on the boat, and bring you the desired happiness and leisure. Huanduy’s battery can be equipped with a Bluetooth function. You can monitor the battery status through your cell phone at any time. Generally, 12V, 24V, and 36V lithium marine batteries are the most popular Battery waterproof grade IP65, you can rest assured on the voyage and passed CE, IEC, UN38.3, MSDS, etc.

With the globalization of lithium ion batteries, more and more crew upgraded yachts and boats to deep-cycle batteries. Lithium ion boat battery are more efficient, and their service life is 10 times that of lead-acid batteries, the same battery capacity, lithium iron phosphate battery (LiFePO4 or lfp batteries) occupy a smaller volume, lighter weight, which is more convenient and lighter on board.  In addition, the power storage capacity of lithium iron batteries is stronger than that of lead-acid batteries, and the cost is more advantageous in the long run.

Lithium ion trolling motor battery is to provide slow and steady power for trolling motors. The best-selling 12V, 24V, and 36v lithium trolling motor batteries are all deep cycle life LiFePO4. Compared with the lead-acid, the important feature of a lithium trolling motor battery is to extend the running time. Generally, the same capacity to run once is two times the capacity of lead-acid batteries. Of course, more efficient power and charging methods, so you can go fishing on the water with more confidence, without worrying about your battery running out of power all the time!

Yes. Lead-acid batteries are easy to replace and cheaper. So in the past, many people choose the battery. With the development of lithium batteries, We can know about the unique performance of lithium iron phosphate batteries. More stable, safer, more cycles, high energy density, especially maintenance much easy, many people tend to choose lithium batteries, and the cost is much lower.

It is possible to charge a Li-ion battery with a lead-acid battery charger. But we should pay attention to match the voltage of the batteries. For example, a 12V battery should use a 12V charger. 14.1-14.4V is the rated charging voltage of the AGM battery. But it is still recommended to use a special charger for the Li-ion battery, but not the lead-acid charger. The main reason is that using a lead-acid charger to charge the lithium battery is not enough, which will lead to the battery’s energy not being up to standard.

Yes. General factory batteries will carry 30%-50% of the power. Lithium battery packs will discharge themselves slightly. But compared with lead-acid batteries, the lithium iron phosphate battery self-discharge rate is much lower. Recommended charging the battery promptly if not used for a long time. When stored in the warehouse, 3 months to charge and discharge once; up to 6 months to charge and discharge once.

Yes. The excellent performance of lithium batteries, such as long life, lightweight, small size. It can provide higher capacity than lead-acid batteries while not shortening their life, high stability, high safety, high charging, and discharging efficiency. These are the absolute advantages for cranking batteries.

Generally, trolling motor operates with 12 V marine batteries. Using lithium iron phosphate (LiFePO4) batteries will extend the running time and service life.
First, confirm the voltage of the trolling motor.
The 12V motor is small and has a cost advantage. One battery is ok. 24V and 36V motors have greater thrust and power and require multiple batteries in series. If you focus on cost, then 12V motors may be better.
If you focus on power and performance, 24V or 36V may better meet your needs.
Second, confirm the current consumption of the motor.
The maximum current consumption of the motor should be less than the maximum current consumption of the battery, so your motor will not exceed the battery power.

  • When charging and discharging the lithium deep cycle lifepo4  battery, ensure the conditions that monitor and protect the battery voltage, current, and temperature.
  •  Avoid discharging the lithium ferro phosphate battery completely.
  • When the  lithium phosphate battery is not used in a long time, it should have 30%~50% SOC.
  • The battery should be stored (more than 1 month) in a clean, dry, and ventilated room with an ambient temperature of 0℃~35℃. Avoid being in strong direct sunlight or a high temperature and high humidity environment.
  • First, to ensure that the charger and the battery match, voltage and current should match. The charging current determines the charging time. The greater current will reduce the charging time.
  • The most direct and simple judgment, to observe the color change of the charger’s indicator light or the light on the appliance. Generally red becomes green, which means full.
  • Detect the voltage of the appliance. The battery power is different. The less power, the lower the voltage.
  • Some good-quality chargers can also detect the voltage to determine whether it is full.
