The 80V 400Ah LiFePO4 Deep Cycle Marine Battery is a high-capacity lithium iron phosphate battery designed to provide reliable and long-lasting power for marine vessels, electric boats, and other high-voltage marine applications.
Built with high-quality LiFePO4 battery cells, this marine battery offers excellent thermal stability, safety, and cycle performance. With up to 4,000 cycles, it provides a significantly longer service life than traditional lead-acid batteries while reducing maintenance and replacement requirements.
The battery features an intelligent BMS (Battery Management System) to monitor and protect against overcharge, over-discharge, overcurrent, short circuit, and abnormal temperature conditions. Its deep-cycle design supports repeated charging and discharging, making it suitable for daily marine operations.

This marine battery uses LiFePO4 (Lithium Iron Phosphate) cells, which offer good thermal stability, safety, and long cycle life.
The battery can provide up to 4,000 cycles under specified testing and operating conditions. Actual cycle life depends on factors such as depth of discharge, charging method, temperature, and operating conditions.
Yes. A LiFePO4 battery can be used as a replacement for suitable lead-acid systems when the voltage, charging system, discharge current, installation space, and electrical interfaces are properly matched.
The battery can be designed for marine environments, but the enclosure, waterproofing, connectors, and installation method should be selected according to the vessel and environmental conditions. An appropriate IP-rated enclosure can be customized if required.
Yes. OEM and ODM customization are available. Custom options can include BMS parameters, communication protocols, connectors, enclosure design, charging requirements, and other electrical specifications.
