Use the CoPow 150Ah lithium-ion battery to keep your boat running longer and enjoy more of life's beautiful moments.
It lasts longer than a 100Ah battery and is cheaper than a 200Ah battery.
1. Longer Service Life
Under standard conditions at 25°C, with a charge/discharge rate of 0.2C, a depth of discharge (DOD) of 100%, and an end-of-life (EOL) capacity retention rate of 80%, our marine batteries can achieve a cycle life of over 6,000 cycles and a service life of more than 8 years.
2. Lighter Weight
A 150Ah lithium-ion marine battery weighs 25–35 kg less than a 150Ah lead-acid battery.
3. Higher Usable Capacity
The rated capacity is the capacity under ideal conditions. In reality, we rarely use more than 150Ah. If you're using a lithium-ion battery, make sure it has at least 90% of its actual usable capacity-that way, you won't end up buying a battery that's short on capacity.
4. Consistent and Stable Voltage Output
One of the advantages of lithium-ion batteries is their stable voltage output, which provides continuous power from a fully charged state to a low-charge state.
5. Faster Charging Speed
Lithium-ion batteries can handle higher charging currents. Taking a 150Ah battery as an example, the charging current for a lead-acid battery ranges from 0.1C to 0.2C (15A to 30A), while that for a LiFePO4 battery can reach 0.5C to 1C or even higher (75A to 150A). It takes 8–12 hours to fully charge a 150Ah lead-acid battery, whereas a CoPow lithium-ion marine battery requires only 1–3 hours.
6. Comprehensive Marine-Grade Protection Design
Specially reinforced for humid, high-salt-fog, and complex marine environments, with key components-from the housing and terminals to screws-treated for corrosion resistance. Available protection ratings include IP65, IP67, and IP68.
High-end material options include 316 stainless steel and anodized aluminum alloy; housing structures can also be customized according to project requirements.
7. Intelligent BMS Battery Management System
In addition to basic functions such as overcharge, over-discharge, overcurrent, short-circuit, high-temperature, and low-temperature protection, it also features the following capabilities:
- High-precision SOC (State of Charge) calculation
- Active cell balancing technology
- Charge and discharge data logging
- Fault diagnosis and early warning
- Multi-level safety protection strategies
Depending on project requirements, advanced features such as a Bluetooth app, CAN Bus, RS485, NMEA 2000, GPS remote monitoring, a 4G IoT platform, a self-heating system, and remote power on/off can be optionally configured to enable smarter vessel energy management.
8. Easier Maintenance
No need to top off electrolyte, no balancing maintenance, and no need to clean corrosion-significantly reducing daily maintenance tasks.
9. Excellent Low-Temperature Performance
Lead-acid batteries are prone to capacity degradation, difficult starting, and reduced runtime in low-temperature environments, whereas CoPow lithium iron phosphate marine batteries maintain stable performance even in cold conditions. Additionally, you can opt for the self-heating feature to further enhance the battery's low-temperature adaptability.
10. Supports Starting and Deep-Cycle Applications
Whether you need a marine starting battery with high cold-cranking current or a deep-cycle battery for extended power supply, CoPow can provide professional solutions tailored to different vessel types and application scenarios, meeting the dual requirements of engine starting and powering onboard equipment.
11. Enhanced Safety
Lithium iron phosphate is currently the safest lithium-ion battery chemistry, offering excellent thermal stability and resistance to thermal runaway. It is neither flammable nor prone to explosion, providing a higher level of safety assurance for vessel operations.
12. Robust Customization Capabilities
As a professional manufacturer of marine lithium-ion batteries, CoPow can deeply customize battery capacity, voltage, dimensions, casing structure, communication protocols, protection ratings, self-heating systems, and brand aesthetics based on different vessel types, application environments, and project requirements, delivering tailor-made battery solutions for OEMs, shipbuilders, and professional users.
