Types and Uses of Marine Lithium Batteries

Lithium iron phosphate (LiFePO4) batteries offer excellent energy efficiency and safety. Because of their lightweight design, high energy density and long service life, most fish boats require two types of 12-volt batteries. A starter battery, used to start the main engine. The other is a deep-cycle battery, used to power the trolling motor and other accessories. There are dual purpose batteries that can fulfill both needs.

1. Starting Battery

Typically used to provide the high power needed to start a marine engine. Mostly used on boats with conventional internal combustion engines to power the ignition system and electronics.

2. Deep Cycle Batteries

Designed for continuous, long-term power supply. Ideal for trolling motors, electronic equipment such as sound systems, fish finders, and GPS, they meet the needs of trolling motors, marine electronics, and auxiliary power, and support long periods of use without frequent recharging dual-cycle batteries

3. Dual Purpose Battery

It can be used as both a starting battery for the engine and a deep cycle battery for the boat. It can be used as both a starting battery for engines and a deep cycle battery for onboard electronics and accessories, providing versatility for a variety of marine applications. Due to space constraints on some boats, dual-purpose batteries have become the preferred choice for this category.

FAQ

Q: Do you need a special charger for lithium marine batteries?

A: Yes, we advise a charger that is compatible with lithium marine batteries. especially those based on lithium iron phosphate (LiFePO4) chemistry, require specific charging to ensure safe and efficient charging.

Q: Can I leave my lithium batteries in my boat over the winter?

A: Yes, but there are a few important considerations to make sure they stay in good condition:

1. Lithium batteries are best stored in a partially charged state (about 50-70% of capacity) to prevent over-discharge during storage.

2. Lithium batteries can withstand a wide range of temperatures, but extreme cold or heat can affect their performance and service life.

3. Most lithium batteries have a low self-discharge rate, but it is good practice to check the battery voltage periodically and recharge as necessary.

4. Disconnect the battery from the boat's electrical system to prevent the battery from draining over time. 5. Ensure that batteries are securely mounted and stored in a manner that avoids any potential damage or exposure to water.

Q: What is the best marine lithium battery?

A: Capacity and Power: Sufficient capacity and power to meet the needs of the boat's electrical system and accessories.

Lifespan: Lithium batteries have a longer lifespan and cycle time.

Weight and Size: Lithium batteries are lighter and more compact, which is beneficial for boats with high weight and space requirements.

Safety and Reliability: Ensure batteries have built-in safety features such as overcharge, over discharge and temperature protection. Reliable performance is critical, especially in the marine environment.

Cost: Evaluate the cost-effectiveness of the battery over its entire service life. ILUMA provides marine 12V,16V,24V,36V lithium iron phosphate batteries, which is the most suitable solution for your fishing boat.

Q: Will a boat motor charge a lithium battery?

A: Yes, a boat motor can charge a lithium battery, but it requires the appropriate charging system and conditions to do so safely and effectively.

Q: What is the best lithium battery for starting outboard motors?

A: There are a few points to consider: High Cold Cranking Current (CCA): sufficient starting power even in cold weather conditions to ensure that outboard engines start quickly and reliably.

Voltage and Capacity: (typically 12V or 24V) has sufficient capacity to meet the starting requirements of your specific engine model.

Durability and longevity: with a long cycle life and rugged construction that can withstand the marine environment and frequent engine starts without degradation.

Size and Weight: Lithium batteries are lighter and more compact, which is advantageous for boats where weight and space are a concern.

Safety and Features: such as overcharge, over discharge and temperature protection to prevent damage and ensure safe operation. We recommend ILUMA 12V125Ah starter batteries.

Q: Are lithium batteries suitable for marine use?

A: ILUMA upgraded lithium marine batteries are significantly lighter and more compact, with increased power, fast charging, and longer service life. The ability of lithium batteries to supply power for a long time is very obvious, and they can even be used for several days. Therefore, lithium batteries are the first choice for marine.

Q: What is the best lithium marine batteries?

A: Best lithium marine batteries and trolling motor batteries we recommend ILUMA 12v 100ah,12v 135ah,12v 150ah etc. lithium batteries.

Q: Can Marine alternators charge my lithium marine batteries?

A: Generally, it is possible to use the alternator to charge the battery, but please note that the power output from the alternator needs to be converted by a charger compatible with lithium batteries; the output voltage of some alternators may not be stable enough, it is recommended to use a voltage regulator to ensure that the output voltage is stable, to protect the charger and the lithium batteries. To ensure smooth charging, the battery BMS or charger's display monitors the battery's charging status.

Q: What batteries do professional fishermen use to meet their needs?

A: Traditional lead-acid batteries have been replaced by lithium batteries, due to the high cost of maintenance and frequent exchange. Lithium batteries are long-lasting, reliable, and lightweight, making them an ideal power source for on-the-water operations.

Q: Are the safest lithium marine batteries a LiFePO4 battery?

A: LiFePO4 batteries have good thermal stability and long service life, their performance and output are more stable and safer, they have superior sealing performance and can withstand a wider range of temperatures, making them ideal for marine applications.

Q: What are the main types of marine deep-cycle batteries?

A: Lead acid batteries and lithium batteries. Lithium batteries have low overall cost and are long-lasting and durable, ILUMA lithium marine battery life lasts up to 10 years or more and is safer and more environmentally friendly.

Q: Are lithium batteries worth using in marine?

A: Compared to lead-acid batteries, lithium batteries have more than 6000+ cycles, which means that they can provide power to your marine for more than 10 years, which is economical and efficient.

Q: How many lithium marine batteries do I need?

A: This will depend on the power needs of the boat, the type of battery, and the power range, most marine batteries need at least two or even more. Firstly, you need to calculate the total power consumption of the electrical equipment you use every day; marine batteries lead-acid batteries, and lithium marine batteries, of course, lithium batteries are more efficient and support deep discharge. Assuming that the total power consumption of a day is 2500Wh, usually, the marine battery is 12V, in this situation, if the lead-acid batteries are used, perhaps you need 5 pieces (100ah/piece), if lithium batteries, you only need 3 pieces (100ah /piece).

Q: Can I start the lithium marine batteries myself?

A: You can start lithium marine batteries yourself, but you must follow professional procedures. Ensuring safety and proper battery operation requires specialized knowledge and equipment. Check that the battery status and voltage are within safe limits, confirm that the charger is compatible with the lithium battery, ensure the wiring and connectors are undamaged, and monitor the charging process for any abnormalities.
