Engineered with automotive-grade Grade-A cells and heavy-duty battery management systems to power marine electric outboards, trolling systems, and light electric mobility.
Why high-performance 72-volt lithium battery engineering is rapidly becoming the standardized powertrain benchmark across both high-speed two-wheelers and high-thrust marine vessels.
The global maritime electrification and light electric vehicle (LEV) sectors are undergoing a massive technological convergence. Historically, trolling motors and small commercial boats operated on heavy, low-voltage 12V or 24V deep-cycle lead-acid banks wired in series. However, as brushless DC (BLDC) and permanent magnet synchronous motors (PMSM) continue to scale in kilowatt capacity, low-voltage systems encounter severe physical limitations characterized by excessive current draw, extreme conductor heat dissipation ($I^2R$ thermal losses), and bulky copper cabling.
Originally refined to satisfy the aggressive acceleration, high peak torque, and ultra-compact packaging demands of performance electric motorcycles, 72V LiFePO4 and Lithium-Ion battery modules have emerged as the optimal power solution for marine boats, commercial catamarans, luxury yachts, and heavy-thrust trolling motors. Operating at 72 volts nominal significantly slashes amperage requirements by over 60% compared to legacy 24V systems delivering equivalent kilowatt outputs.
From demanding marine environments exposed to saltwater spray and high vibrations to rough cross-country trails, our battery platforms guarantee non-stop performance.
Continued support and protection, ensuring your trust even beyond the warranty period with complete lifecycle maintenance peace of mind.
Lasting a decade or more, delivering outstanding cycle endurance (>4,000 cycles at 80% DoD) and minimizing recurring replacement costs.
Zero fluid top-ups, no terminal acid corrosion, and no equalization charging required, offering unmatched cost-effectiveness.
Reliable power for exciting adventures and renewed energy, featuring high continuous discharge rates for instant planing speed.
No heavy toxic lead, zero hazardous acid leakage, and zero operational emissions—fully aligned with marine eco-reserve guidelines.
Equipped with intelligent BMS for comprehensive real-time protection against over-voltage, over-current, short-circuit, and thermal spikes.
Delivering specialized engineering capabilities customized for distinct vessel classes, trolling demands, and extreme environmental conditions.
Modern tournament bass boats and offshore coastal fishing vessels utilize powerful trolling motors exceeding 100+ lbs of thrust with advanced GPS spot-lock and autopilot functions. A 72V lithium pack supplies steady voltage throughout the entire discharge curve, eliminating the progressive speed and thrust degradation notorious with lead-acid batteries. Anglers maintain pinpoint positioning in heavy wind and fast river currents all day long.
For electric tenders, RIBs, leisure catamarans, and lake tour boats, 72V electric propulsion delivers whisper-quiet, zero-emission navigation. With built-in CAN-bus and NMEA 2000 communication protocols, our 72V packs seamlessly integrate with marine helm displays, giving captains accurate state-of-charge (SOC), remaining cruising range, real-time power draw, and predictive maintenance alerts.
Beyond propulsion, modern yachts deploy 72V DC microgrid architecture to power heavy hydraulic thrusters, high-capacity watermakers, stabilize gyro stabilizers, and operate air-conditioning silent night cycles without running noisy, fume-producing diesel generators.
