Lithiumbatteries are revolutionising the marine industry by providing efficient, reliable and long-lasting power for vessels of all sizes. Whether you own a fishing boat, a yacht, a sailboat or even a houseboat, switching to lithium-ion batteries can significantly improve your boating experience. They offer many advantages over traditional lead-acid batteries, making them the best choice for marine applications.
Our company offers a great battery for fishing, very suitable for boats – Li-ion 12V 200Ah battery.
Advantages for the fisherman:
Long life ~5000 cycles (80% capacity remaining)
Fast charging – so you’re ready even at the last minute
Compact shape – fits in any compartment of the boat
Maintenance-free
Quiet operation – does not disturb fish
Why choose lithium batteries for your boat?
1. Lightweight and compact design
They are much lighter than traditional lead-acid batteries, reducing the overall weight of your boat. This means better performance, more fuel efficiency and higher speeds. Their compact design also frees up valuable space on your boat, allowing more room for storage and other essentials.
2. Longer service life
Lithium batteries, especially lithium iron phosphate (LiFePO4), have an extremely long lifetime of up to 3000-7000+ cycles. This means that batteries will not need to be replaced as often, making them a more cost-effective investment in the long run.
3. High energy efficiency
Lithium batteries are more energy efficient than traditional batteries, with charge/discharge efficiencies of up to 95%. This allows you to store and use more of the energy you generate from solar panels or a ship’s generator, reducing waste and maximising energy availability.
4. Faster charging
One of the main advantages of lithium batteries for boats is their ability to charge faster than lead-acid batteries. Whether you charge from shore power, solar panels or the boat’s engine, lithium-ion batteries take less time to recharge, so you can be up and running and back on the water again in no time.

5. Deep cycle batteries
Ideal for deep cycling, i.e. they can be discharged to a much lower level without damage, unlike lead-acid batteries, which need to be recharged at a higher level to avoid failure. This allows electronics, lighting, trolling motors and other systems to be used for longer periods of time without fear of battery drain.
6. Maintenance-free operation
Maintenance-free. With no restocking or corrosion to worry about, they are hassle-free and ideal for long-term use in marine environments. So you can focus more on enjoying your time on the water and worry less about battery maintenance.
7. Security and reliability
The marine environment can be harsh, but lithium batteries have built-in safety features including protection against overcharging, over-discharging and overheating. These batteries also feature a Battery Management System (BMS) for optimum performance and safety, so you can have peace of mind during long journeys.
8. Wide operating temperature range
It can operate efficiently at a wide range of temperatures from -20 °C to 60 °C. This makes them ideal for use in a wide range of marine conditions, whether you’re sailing in hot tropical waters or the colder northern seas.
9. Environmentally friendly and sustainable
Lithium batteries are much greener than lead-acid batteries. They are non-toxic, recyclable and do not contain harmful chemicals such as lead or sulphuric acid, reducing the environmental impact on marine ecosystems.

Lithium battery applications for ships:
- Trolling motors: provide consistent and long-lasting power for electric trolling motors, so you can fish for longer without worrying about running out of battery.
- Power systems for houseboats: provide reliable and maintenance-free power for appliances, lighting and other household systems.
- Sailing electronics: reliably use power for navigation, communication and safety systems to stay safe at sea or on other bodies of water.
- Solar-powered boats: perfectly matched with solar panels for efficient energy storage and fast charging for the most efficient use of renewable energy.
- Backup power: Lithium batteries are a reliable backup power source in case of engine failure or other emergencies, ensuring your safety in the water.
