Singapore-based OceanLink Shipping cut operating costs dramatically by replacing diesel generators with 48V LiFePO4 battery packs across its 12-vessel fleet.

    The Problem

With rising fuel prices, the company’s 15-year-old vessels were spending $18,000/month per ship on auxiliary power for refrigeration and navigation systems.

    The LiFePO4 Solution

Engineers installed modular 48V 600Ah LiFePO4 battery banks with these specs:

1.2-hour rapid charging via shore power.

2. Seamless integration with existing alternators.

3. NEMA 4X corrosion-resistant enclosures.

4. Operational Improvements.

Hybrid Power Mode: Batteries now handle 70% of hotel loads, reducing generator runtime from 24/7 to 6 hours daily.

Regenerative Charging: Harvested energy from propeller freewheeling adds 5-8% daily charge

Maintenance Savings: Eliminated weekly battery water refills required for lead-acid systems

    The Results

$5,400/month fuel savings per vessel

14% longer generator lifespan due to reduced workload 28% decrease in CO2 emissions

This case proves industrial-grade LiFePO4 systems aren’t just for small crafts – they’re revolutionizing maritime energy economics at scale.
