25.6V 200Ah Marine LiFePO4 Battery 5120Wh 24V Thruster Trolling Motor 150A BMS

Product Specification

25.6V 200Ah Marine LiFePO4 Battery 5120Wh 24V Thruster Trolling Motor 150A BMS IP65

Bow thrusters, anchor windlasses and 24V trolling motors draw hard, brief currents that stress a single 12V pack. This 25.6V 200Ah marine LiFePO4 battery stacks eight cells in series to hit 24V directly, storing 5120Wh and feeding 150A continuously without a step-up converter. One case replaces a pair of 12V 200Ah units and the tangle of balancing cables between them.

Specifications

Core Specifications

This marine battery holds 25.6V nominal across a 200Ah capacity for 5120Wh of energy. Internal resistance stays under 30 milliohms, efficiency is 98 percent and self discharge is below 5 percent per month. Cycle life exceeds 4000 cycles at 1C and 80 percent depth of discharge. The cells are wired 8 series 2 parallel (8S2P). Case dimensions are 522mm by 240mm by 222mm and weight is 38 kilograms. M8 terminals sit on an ABS housing sealed to IP65.

Cycle Life and Longevity of This Marine Battery

A charter fleet that cycles this marine battery each day still reaches eight to ten years before hitting 80 percent capacity. Running 24V in a single case halves the interconnection losses and cell drift of paired 12V banks, so this marine battery delivers more usable energy from the same footprint over its life.

Why LiFePO4 Beats Lead-Acid Onboard

Building 24V from two 12V lead-acid batteries doubles the cable runs and invites imbalance as the weaker unit drags the pair down; this marine battery spans 24V in one case so thrusters see a balanced supply. It is lighter than the equivalent lead bank, needs no watering, and holds voltage steady through the high inrush of a bow thruster. The single enclosure also means one BMS watching one set of cells, which keeps the pack safe and simple to service in a crowded forward compartment.

Charging Recommendations

Charge this marine battery at 28.4 to 29.2V with 100A recommended and 150A maximum. For long lay-ups, store near 50 percent SOC and top up every few months, and verify terminal torque before reconnecting thruster cables after any service.

Environmental Tolerance of This Marine Battery

This marine battery discharges from -20C to 60C and charges from 0C to 55C, with storage from -20C to 60C and a 65C BMS cutoff. The IP65 ABS shell blocks salt spray and locker condensation, and its M8 studs resist corrosion in the damp forward compartments where thrusters live.

Communication and Monitoring of This Marine Battery

An integrated 150A BMS protects this marine battery against overcharge at 29.2V, over-discharge at 20V, short circuit within 300 to 800 microseconds and 65C overheating. State of charge and current are available through an optional monitor, giving the helm a precise read during docking and anchoring.

Applications for This Marine Battery

This marine battery drives bow and stern thrusters, anchor windlasses, 24V trolling motors, davit winches and 24V house loads on motor yachts and workboats. It also backs hybrid propulsion buffer banks. Parallel units scale to 400Ah, and the 24V output removes the converter that standalone 12V packs require.

Installation and Safety of This Marine Battery

Mount this marine battery level and ventilated, torque the M8 terminals to 8 to 10 Nm and size the main fuse for 150A continuous. Keep positive and negative cables equal length to balance current, charge only above 0C, and check terminal torque after the first thruster test.

Frequently Asked Questions

Q: Is 25.6V safe for a 24V thruster?
A: Yes. A 24V thruster accepts 25.6V nominal, and this marine battery stays within the motor manufacturer tolerance across its whole SOC range.

Q: Can I parallel two units for 400Ah?
A: Parallel operation is supported when both units are at the same state of charge and charging voltage. Use equal-length cables for this marine battery pair.

Q: Do I still need a DC-DC converter?
A: No. Because output is already 24V, this marine battery feeds thrusters and 24V loads directly, so the step-up converter can be removed.

Q: Will it damage my 24V electronics?
A: No. Output stays within 24V equipment tolerance from full to empty, so this marine battery is safe for nav and comms gear.

Q: How does it handle thruster inrush?
A: The 150A continuous and 300A pulse rating of this marine battery absorb thruster inrush without the voltage sag a lead pair shows.
