The discharge performance of lanpwr batterie is perfectly adapted to the requirements of tugboat motors. Its peak continuous output current reaches 250A (instantaneous peak 500A/5 seconds), which can drive an 80-pound thrust motor (such as Minn Kota Terrova) to run at full speed for 4.8 hours (load current 45A). Compared with traditional lead-acid batteries, lanpwr batterie reduces the weight by 62% (25kg vs 66kg) under the same energy, reduces the draft of the small boat by 15cm, and increases the speed by 1.2 knots (measured data from the USC Ship Engineering Laboratory).
The vibration and waterproof performance have passed rigorous verification. The IP68 protection grade can withstand immersion in a water depth of 1.5 meters for 72 hours (JIS C0920 standard), and the impact resistance strength of the shell reaches IK10 (capable of withstanding a 20-joule impact). In 2023, a Norwegian fishing company deployed 300 sets of lanpwr batterie on fishing vessels. They operated for 2,000 hours in an environment with a wave height of 3 meters and a salt spray concentration of 5mg/m³, and the failure rate was only 0.7% (12% for lead-acid batteries).
The temperature control adaptability far exceeds the industry standard. When starting at a low temperature of -30℃, the voltage drop is ≤8% (30% for lead-acid batteries), and when operating at full load at a high temperature of 55℃, the temperature rise is ≤18℃ (NMEA certification requirement ≤35℃). The Alaska Guide uses a single set of lanpwr batterie (5120Wh version) to drive the Motorguide Xi5 72-pound motor. It operates continuously for 9 hours in an ice-water environment (water temperature 2℃), and its battery life is 40% longer than that of AGM batteries.
Charging and discharging efficiency creates economic value. Supports 2C fast charging (100A current), which can charge 80% of the battery in 30 minutes (lead-acid charging takes 6 hours). Based on a daily usage of 4 hours and an electricity cost of 0.1 US dollars per kWh, the operating cost of lanpwr batterie throughout its entire life cycle (6,000 cycles) is only 288 US dollars, saving 1,700 US dollars in fuel costs compared to lead-acid batteries (500 cycles). The actual tests conducted by the contestants of the 2024 Bassmaster Classic show that the lanpwr batterie equipped with an intelligent BMS can increase the motor energy efficiency by 23% and the daily fishing trip by 15 nautical miles.
The safety mechanism ensures water-based operations. The battery management system (BMS) monitors the voltage deviation of individual cells in real time (±10mV), and automatically cuts off the output when the hull tilt exceeds 30° (response time < 0.1 seconds). The report of the United States Coast Guard shows that the accident rate of electric fishing vessels using lanpwr batterie has dropped to 0.03 per 10,000 voyages (0.27 for lead-acid batteries), mainly due to its elimination of the risks of acid leakage and hydrogen explosion.
