MANLY Battery

MANLY Battery manufactures high-capacity lithium iron phosphate (LiFePO4) energy storage solutions engineered specifically for boaters and yacht owners.

Designed to replace traditional lead-acid systems, these marine lithium batteries operate reliably under demanding conditions and extreme temperatures ranging from -20°C to 75°C. High energy density and maintenance-free operation make these power units suitable for both house loads and high-draw dual-purpose applications.

Large-scale production facilities give MANLY Battery a daily output capacity of 6 MWh, maintaining consistent quality across both standard and custom battery configurations.

Engineered to deliver a 98% energy efficiency rate, these LiFePO4 units charge rapidly and handle thousands of deep-discharge cycles over an expected operational life of 8 to 10 years or more. Integrated Battery Management Systems (BMS) protect cells against overcharging, deep discharge, and voltage spikes.

Built to withstand constant vibration, mechanical shocks, and harsh marine environments, the battery casings prevent water intrusion and corrosion while completely eliminating toxic chemical leaks.

The company produces units in various sizes and voltage specs to fit tight engine rooms and cramped storage lockers. International safety standards and testing certifications including UN38.3, IEC62133, UL, and CE cover the entire marine product line.

Flexible design options allow boaters to tailor battery capacity and form factors to specific onboard power grids, whether outfitting small recreational sailboats or large luxury motor yachts.

In addition to supplying customized setups backed by a 10-year warranty, the company maintains round-the-clock technical support for installation guidance and system planning.
