The LANPWR 12V 300Ah battery (nominal capacity 3.84kWh) can supply 3.07kWh of available energy at 80% depth of discharge, sufficient to run a 1500W RV air conditioner for 1.84 hours (inverter efficiency 90%), or provide a full 48-hour battery life for a 200W refrigerator (average daily 1.6kWh). It can power a 1800W induction cooker to run for 1.5 hours if charged by a 3000W inverter, or it can run a 50W LED light (20 hours), a 100W TV (8 hours), and a 20W router (40 hours) simultaneously. The 2023 Tesla Powerwall comparison review suggests that if this battery supplies power to a standard off-grid house (with a daily average output of 5kWh), its level of electricity self-sufficiency is 61% (when lead-acid batteries achieve only 32%).
In heavy-duty use, the LANPWR battery provides a 100A continuous discharge rate (300A peak/10 seconds), enough to charge industrial-strength power tools: i.e., to power a 1500W cutter (1.8 hours), an 800W power drill (3.4 hours), or a 600W water pump (4.6 hours). In the course of verification of the 2024 African Mobile medical Vehicle project, one battery pack ran continuously for 72 hours for the vaccine refrigeration box (120W/24 hours), ultrasound machines (300W/6 hours), and surgical lamp (100W/8 hours). After the diesel generator was replaced, $5,200 per year in fuel expenses were saved and carbon emissions reduced by 12 tons.
From a cost-effectiveness point of view, the battery has a lifespan of 6,000 cycles (DOD 80%). On the basis of one charge and discharge per day, it can be used continuously for 16.4 years at a cost of as low as 0.006/kWh (0.024/kWh for lead-acid batteries). If off-grid hut is supplied by power with 800W photovoltaic panel (averaging 3.2kWh/day), the minimal load (lighting + fridge + router) can be fully charged and a saving of 1,140 bills of the grid a year is earned at 0.3/kWh. The instance of the Alaska Polar Observatory in 2023 demonstrates that lanpwr battery maintained powering of a 1kW heater with 85% capacity for 2.6 hours at -40℃, whereas lead-acid battery ran only for 0.9 hours with the same testing conditions.
On the aspect of ruggedness of environments, its IP67 sealing and operating temperature of -40℃ to 60℃ allows various applications:
Marine equipment: Power Marine radar (500W, 5.5 hours) or sonar (200W, 14 hours)
Emergency power source: Provide CPAP ventilator (60W) with 50 hours of power, or maintain 500W medical equipment (5.6 hours) in use
Outdoor operation: Powers 2000W welder (1.3 hours) or 1200W industrial vacuum (2.2 hours)
During the 2022 California wildfires rescue mission, three sets of LANPWR batteries in parallel connection (total capacity of 9.2kWh) powered a communication base station (800W) for 11.5 hours and 72 hours of network coverage for the area in need. They were 41% more efficient than fuel-based generators. Its Bluetooth monitoring feature allows real-time monitoring of the distribution of loads. One RV owner extended the daily battery life from 7.2 hours to 10.5 hours by optimizing the time-sharing use of the air conditioner (800W) and microwave oven (1000W).
In terms of safety design, this battery has passed UL 1973 certification, with a thermal runaway temperature of 268℃ and a short-circuit protection response of less than 2ms. In the 2024 test, the temperature after puncture in full charge was only 58℃ (205℃ for lead-acid batteries), without any leakage of electrolyte. The modular design can be expanded to 6 groups in parallel (total capacity: 18.4kWh), with only 198kg (540kg for the lead-acid solution) weighing, reducing the installation volume by 73% for space-constrained applications such as ships and mining cars.
Real energy efficiency case
Coffee truck operation: Run 18 million business coffee machines (1.6 hours per shift), with the daily manufacturing capacity of 20 cups, which saves $28 per day of generator rental
Film shooting: Power was provided for 2000W movie and TV lighting (1.4 hours) and 400W cameras (6.8 hours), and the noise level was reduced from 75dB to 0dB
Agricultural irrigation: Provides a 750W water pump (3.7 hours) for average daily irrigation for 5 mu land, with 62% savings over the diesel alternative
Through smart load planning (e.g., operating washing machines during peak photovoltaic hours), customers can increase the LANPWR battery utilization rate from 65% to 92%, completely satisfying the different power demands from micro households to large-scale industries.
