Massive Capacity, Extended Runtime - Power Your Boat Through a Full Day on the Water with Ease!
200Ah isn't our limit-if you need a higher capacity, we can customize a solution just for you!
1. Extra-Large Capacity, Extra-Long Run Time
With a storage capacity of up to 5.12 kWh, it easily meets all-day cruising needs. Even when driving high-thrust electric propellers or onboard equipment for extended periods, frequent recharging is not required.
2. Powerful and Stable Power Output
The discharge curve of LiFePO4 batteries is smoother than that of lead-acid batteries. Even as the charge level drops from 100% to 50% and then to around 20%, the battery maintains a stable voltage plateau, continuously powering onboard equipment such as electric thrusters, fish finders, navigation devices, water pumps, and lighting systems.
3. High Capacity, Lightweight
For the same 200Ah high-capacity battery, a 24V lithium-ion battery is 50% to 70% lighter than a lead-acid battery, weighing only 45 kg. This reduces a vessel's dead weight, frees up more cargo space, and results in a lighter stern, shallower draft, and lower navigational drag.
4. 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-ion batteries have been reinforced in every aspect-from structural design to material selection-to withstand marine environments. This includes IP65, IP67, or even higher protection ratings; 316 stainless steel screws, terminals, and fasteners; and enclosures made of reinforced ABS, PC+ABS, or metal-coated corrosion-resistant materials.
5. Comprehensive Battery Management System
Our lithium-ion marine batteries not only feature basic protection functions-such as overcharge, over-discharge, overcurrent, short-circuit, and high/low-temperature protection-but also integrate communication protocols including CAN Bus, RS485, and NMEA 2000.
This enables data connectivity with onboard display systems, inverters, motor controllers, and energy management systems, allowing crew members to view the battery's 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 are available for you to explore.
6. Smart Low-Temperature Heating Function
The CoPow 24V 200Ah marine lithium-ion battery is equipped with a smart low-temperature self-heating system. When the ambient temperature falls below the safe charging range, the Battery Management System automatically detects the cell temperature and prioritizes activation of the heating module.
Once the cell temperature is raised to a range suitable for charging, the system allows the battery to begin charging. Even in low-temperature environments, our marine batteries maintain stable performance.
7. Bluetooth Smart Monitoring
View voltage, current, SOC, battery health, and cycle count in real time via the mobile app, making battery management more intuitive and efficient.
8. Durability
Featuring brand-new, high-quality lithium iron phosphate (LiFePO₄) cells, the battery offers a cycle life exceeding 6,000 cycles and a service life of 8 to 10 years.
9. Reduced System Complexity
A single 24V 200Ah module provides high-capacity energy storage without the need to connect multiple battery modules in series to reach the target voltage, thereby reducing installation complexity and the risk of system failure.
