Enjoy the freedom of life on the water without worrying about battery life - CoPow 12V 200Ah Marine Battery makes it possible!
The high-capacity 200Ah battery lets you cruise all day with ease, and you'll still have plenty of power left when you return.
1. Exceptionally Long Battery Life
Featuring a high-capacity 200Ah design, it can continuously power onboard equipment-such as trolling motors, fish finders, navigation devices, refrigerators, and lighting-for over a day.
2. Over 6,000 Cycle Life
Equipped with Grade A LiFePO4 cells, it delivers a cycle life exceeding 6,000 cycles under conditions of 25°C, 0.2C, and 100% DOD, with a service life of over 8 years.
3. Lighter Weight
A 200Ah lithium-ion battery is approximately 30 kg lighter than a 200Ah lead-acid battery, providing more power while freeing up space in the cabin for additional gear.
4. More Stable Voltage Output.
From setting out in the morning to returning home at night, power remains plentiful.
5. Faster Charging
A full charge can be achieved in just 1–3 hours.
6. Longer Runtime.
The 200Ah lithium-ion battery has a large capacity and is highly durable. Combined with the voltage characteristics of lithium-ion batteries, this makes it the battery type with the longest runtime.
7. Military-Grade Protection Design
Marine batteries face long-term exposure to harsh conditions such as high humidity, salt fog corrosion, constant vibration, and temperature fluctuations. CoPow marine lithium batteries are reinforced for the marine environment in every aspect-from structural design to material selection-including IP65, IP67, or even higher protection ratings; 316 stainless steel screws, terminals, and fasteners; and housings made of reinforced ABS, PC+ABS, or metal-coated anti-corrosion materials.
8. Comprehensive Battery Management System
Our marine lithium-ion batteries not only provide basic protection functions-such as overcharge, over-discharge, overcurrent, short-circuit, and high/low-temperature protection-but also integrate communication protocols like CAN Bus, RS485, and even NMEA 2000.
This enables data connectivity with onboard display systems, inverters, motor controllers, and energy management systems, allowing crew members to view battery status (SOC), voltage, current, remaining runtime, and fault conditions in real time.
In addition, advanced features such as active balancing technology, Bluetooth app monitoring, remote data management, and smart pre-charging await your exploration.
9. Simpler Maintenance
No more wasting time on the complex and tedious maintenance required by lead-acid batteries. Simply check the app to easily monitor the battery's operating status and promptly and accurately identify and resolve issues.
10. Supports Capacity Expansion
Supports connecting multiple battery packs in series or parallel, allowing for expansion based on the vessel's needs.
A wide range of customization options to meet all your needs.

FAQ
Q: How long will the 12V 200Ah lithium battery last?
Every CoPow lithium-ion marine battery uses high-quality lithium iron phosphate cells, with over 6,000 charge-discharge cycles and a service life of 8 to 10 years.
Q: What is the price of 12V 200Ah lithium battery?
The price of a CoPow 12V 200Ah lithium-ion battery varies depending on the cell brand, battery management system configuration, casing material, protection rating, and features such as Bluetooth, heating, and CAN communication. For specific pricing, please contact the CoPow sales team for the latest quote.
Q: Is it better to have 2 100Ah lithium batteries or 1 200Ah lithium battery?
If there is sufficient installation space and you want simpler wiring and a more stable system, a single 200Ah lithium-ion battery would be the better choice.
If you need to distribute the weight, increase installation flexibility, or make future capacity expansion easier, two 100Ah lithium-ion batteries would be the better option. Since both solutions have the same total capacity, the choice should be based on the vessel's layout and operational requirements.
