Custom marine LiFePO4 batteries for lead-acid replacement, engine starting, trolling motors and onboard house power.
With more than 20 years of battery manufacturing experience, we support boat builders, marine equipment suppliers, battery brands and distributors with battery sizing, Smart BMS configuration, system integration, sample testing and OEM production.
The correct marine battery depends on the engine, trolling motor, onboard electrical loads, required runtime, charging equipment and available installation space.
High-current LiFePO4 battery configurations are available for compatible marine engines after the required CCA or MCA, alternator output and charging system have been confirmed.
Deep-cycle marine LiFePO4 batteries provide consistent energy for trolling motors, fish finders, navigation equipment, lighting, refrigeration, pumps and other onboard electronics.
House battery systems are configured around daily onboard energy use, inverter power, peak current, required runtime and available charging energy.
Dual-purpose batteries are developed for approved applications that require both engine-starting current and energy for onboard equipment from one battery.
A standard deep-cycle battery should not be used for engine starting unless it has a verified starting-current rating. A starting battery should not power a trolling motor unless it is approved for dual-purpose operation.
Marine lead-acid battery banks can often be replaced with LiFePO4 batteries, but the conversion must account for more than voltage and capacity.
Before recommending a replacement battery, we review:
A DC-to-DC charger, external alternator regulator or another approved current-control method may be required depending on the vessel’s charging system.

A dependable onboard electrical system requires correct battery sizing, charging compatibility, cable selection and circuit protection.
Marine LiFePO4 battery integration can include:

The Smart BMS monitors battery voltage, current and temperature while protecting the battery during charging and discharging.
CAN and RS485 communication can be configured for qualified OEM projects when the connected marine equipment requires battery data. Protocol, firmware and cable compatibility must be confirmed before production.
High-current LiFePO4 batteries for compatible marine engines with confirmed CCA, MCA, alternator and charging requirements.
Deep-cycle batteries for 12V, 24V and 36V trolling motors. Capacity is selected according to motor current, operating speed and required runtime.
Stable battery power for fish finders, sonar, GPS, navigation and communication equipment.
Extended runtime for lighting, refrigeration, pumps, inverters and other onboard electrical loads.
| Feature | Lead-Acid | LiFePO4 |
|---|---|---|
| Weight | Heavier | Lower weight for comparable usable energy |
| Usable Capacity | More limited | Higher usable percentage on approved systems |
| Charging | Lower charge acceptance | Higher charge acceptance within specified limits |
| Cycle Life | Generally shorter | Generally longer under specified conditions |
| Voltage | Greater voltage drop during discharge | More stable discharge voltage |
| Monitoring | External monitor often required | Integrated monitoring available on selected batteries |
Actual performance depends on the battery model, operating temperature, charge and discharge rates, charging equipment and permitted depth of discharge.
We manufacture custom marine LiFePO4 batteries for boat builders, marine equipment manufacturers, battery brands, distributors and system integrators.

Confirm the required CCA or MCA, engine type, alternator output, charging voltage, terminal layout and installation dimensions.
Confirm the motor voltage, maximum current, operating speed, required runtime and charging method.
Calculate daily energy use from lighting, refrigeration, electronics, pumps and inverter-powered equipment. Then confirm the required runtime and available charging energy.
Choose a verified dual-purpose battery when one battery must provide both engine-starting current and energy for onboard equipment.
Yes, in many marine systems. Check the system voltage, charging settings, alternator output, required CCA or MCA, BMS current, cables, fuse protection and installation dimensions before replacement.
Starting batteries deliver short bursts of high current for compatible engines. Deep-cycle batteries provide steady energy for trolling motors and onboard equipment.
Selected batteries support Bluetooth monitoring for state of charge, voltage, current, temperature and operating status.
Yes. A compatible solar charge controller with charging settings suitable for the approved LiFePO4 battery specification is required.
Selected deep-cycle batteries support series or parallel connections. The permitted configuration and connection requirements must be confirmed before installation.
Selected models provide IP-rated protection. The exact rating should be confirmed for the battery model. Installation in a secure and protected battery compartment is still recommended.
Send us the required voltage, capacity, CCA or MCA, continuous and peak current, installation dimensions, charging equipment, communication requirements and estimated order quantity.
Our engineering team will review the application and recommend a suitable marine LiFePO4 battery configuration.
