Explore our industrial-grade marine products engineered for harsh saltwater operational environments.
A comprehensive analysis of energy transition in marine commercial transport, OEM yacht building, and naval electrification.
The global marine battery market is undergoing a seismic paradigm shift. Driven by international decarbonization mandates established by the International Maritime Organization (IMO) and regional environmental regulations such as the EU Green Deal, commercial maritime operations and recreational shipbuilders are aggressively replacing traditional combustion engines and legacy lead-acid energy stores with high-density Lithium Iron Phosphate (LiFePO4) and advanced energy management systems. As a tier-1 wholesale boat battery factory and supplier, our manufacturing infrastructure delivers certified, resilient, and scalable marine power solutions engineered to withstand extreme hydrodynamic and environmental stresses.
Modern marine electric propulsion systems require maximum energy retention within tight engine compartment footprints. Our volumetric energy density exceeds 210 Wh/kg at the cell level, allowing custom vessel builders to reduce total hull weight while doubling operational range per charge cycle.
Saltwater corrosion, mechanical pounding from wave action, and thermal runaway risks represent critical hazards. By utilizing Grade-A prismatic LiFePO4 cells wrapped in IP68 anti-corrosive aluminum enclosures, our battery banks deliver non-combustible stability across operational ranges from -20°C to 65°C.
Seamless communication between battery banks, outboard motors, solar controllers, and helm displays is vital. Our proprietary Smart BMS natively supports CAN-bus, RS485, and NMEA 2000 telemetry protocols for real-time State of Charge (SoC) and State of Health (SoH) diagnostics.
Tailored power architecture engineered to exact client specs for commercial fleets, passenger ferries, and luxury yachts.
As a global marine procurement manager or shipbuilder, sourcing high-reliability power systems demands more than standard off-the-shelf battery packs. Commercial buyers face stringent compliance standards, duty cycle targets, and customized structural requirements. Our engineering facility operates dedicated OEM/ODM production lines offering modular 12V, 24V, 48V, 96V, and high-voltage 400V–800V marine battery systems.

"Our OEM direct procurement model eliminates middle-layer distribution markups while granting enterprise partners access to custom busbar layouts, solid-state BMS integration, and bespoke outer housing geometries suited for custom hull designs."
Combining world-class hull design standards with cutting-edge clean energy propulsion systems.
Building a great boat and outfitting it with a robust power system comes down to three core fundamentals: Time-honoured design, premium materials, and construction standardisation.
Our value goes beyond that of just a great product for a great price. We engineer whole-vessel reliability by combining world-class marine hardware with factory-direct energy storage units.
We’ll happily come to you if you’d like to test systems, provide you with flexible finance and rental options, and deliver comprehensive aftercare and maintenance services to maximize the efficiency and performance of your boats for now and for the future.
By bringing together the resources of the global marketplace in renowned German hull designers Klaus Filter, Graeme King, the Flying Eagle Boat Company, and a group of business, engineering, and rowing talents in the USA, WinTech Racing and Green have created an organization dedicated to:
Green is your complete marine resource. We also offer coaching launches and trailers, oars, deep-cycle auxiliary batteries, electric outboard packs, a full inventory of spare parts, as well as a comprehensive line of accessories, tools, and equipment.
Deep-dive analysis of hardware safety mechanisms, salt-mist protective coatings, and intelligent monitoring.
Unlike passive balancing systems that bleed off energy as heat, our Smart Active BMS transfers energy from higher-voltage cells to lower-voltage cells dynamically during charge and discharge phases with 99.4% efficiency, optimizing total usable capacity.
Navigating in arctic or sub-zero maritime climates can degrade standard lithium performance. Integrated silicone heating pads auto-engage when charging temperatures drop below 0°C, ensuring rapid recharging without lithium plating.
Conforming to ISO 16750-3 heavy commercial marine vibration standards, our battery modules feature structural internal potting, laser-welded busbars, and reinforced anti-shock cell brackets designed to absorb continuous 5G wave slamming.
Forecasting the next decade of solid-state marine storage, hybrid hydrogen fuel cells, and AI diagnostics.
As solid-state electrolytes mature, marine applications will lead adoption due to the non-flammable characteristics and 400+ Wh/kg energy density capabilities. Our R&D center is currently prototyping solid-state marine modules for testing in commercial ferry fleets by 2027, cutting system mass in half.
For long-range trans-oceanic commercial vessels, pure electric drive is augmented by hydrogen fuel cells. Our factory is developing dual-input smart BMS units that manage charge acceptance dynamically from both hydrogen fuel cell arrays and high-capacity LiFePO4 buffer banks.
Future fleet efficiency relies on predictive maintenance algorithms. Integrated IoT modules wirelessly upload real-time cell parameters to cloud servers, utilizing AI models to predict potential cell degradation months before operational failure occurs, minimizing unscheduled dockyard downtime.
Adhering to international circular economy standards, our production plant ensures 95% of active cell materials (Lithium, Iron, Phosphate, Copper, Aluminum) are recoverable at end-of-life, reducing the carbon footprint of marine energy systems over their entire life cycle.
Ensuring smooth international customs clearance, transport compliance, and worldwide marine class approvals.
Exporting battery systems globally demands strict adherence to international maritime safety codes and dangerous goods shipping protocols. Our factory handles full paperwork, testing verification, and UN packaging specifications to streamline logistics for global commercial buyers.
Fully tested for altitude simulation, thermal shock, vibration, impact, external short circuit, and forced discharge.
Certified for stationary and motive marine energy storage safety standards required across Europe and North America.

LiFePO4 (Lithium Iron Phosphate) delivers over 10x the cycle life of traditional lead-acid/AGM batteries (up to 7,000 cycles vs 350-500 cycles). Furthermore, LiFePO4 offers 100% depth of discharge without voltage sag, weighs 60-70% less, recharges significantly faster, and poses zero risk of acid leaks or explosive hydrogen gassing inside sealed hull compartments.
Our proprietary marine Smart BMS features multi-tiered protection against over-charge, over-discharge, over-current, short circuits, high/low temperature cut-off, thermal runaway detection, cell imbalance monitoring, and salt-air insulation resistance checks. It also supports active cell balancing to maximize overall pack longevity.
