The LANPWR 300Ah battery (12V/3.84kWh) is priced at €629. Its price per kilowatt-hour is only €0.0026/kWh, calculated over 6,000 cycles (DOD 80%), 76% lower than lead-acid batteries (€0.011/kWh). For a user consuming an average of 3kWh electricity daily, the total electricity cost in 15 years is only €42 (€180 for lead-acid batteries). A 2024 study by the German Energy Agency illustrates that the payback time of the investment in this battery combined with an 800W photovoltaic panel is 3.8 years (7.2 years for the lead-acid alternative), and the annual profit from the peak-valley electricity price arbitrage is €210, 41% higher than that of lead-acid batteries.
In performance specs, its 95% charge and discharge efficiency (80% for lead-acid batteries) has raised the practical use rate of daily photovoltaic power generation from 2.56kWh to 3.07kWh (20% higher). For instance, the RV air conditioner (1500W) can run 1.84 hours on a single charge, 80% longer than the identical capacity lead-acid battery (1.02 hours). According to the actual test conducted by the Spanish RV Association in 2023, the vehicle equipped with this battery has 1.2 hours more air conditioning running time than the lead-acid solution under the condition of an ambient temperature of 35℃, and the temperature fluctuation in the vehicle is reduced by ±1.5℃.
In terms of adaptability to harsh environments, LANPWR batteries still have 85% of their capacity (3.26kWh) available at the low temperature of -30℃, while lead-acid batteries are only capable of 40% (1.54kWh). Test results from the Norwegian Arctic research Station in 2022 show that it provided power for a 1kW heating device for 2.6 hours at -40℃ (0.9 hours for lead-acid batteries), and the temperature difference between the battery cells was maintained within ±2℃. The 60℃/1000 hours high-temperature experiment showed that the capacity fading rate was only 0.5% (3.8% for lead-acid batteries). UL 1973 certification showed that its thermal runaway temperature was 268℃, 98℃ higher than ternary lithium batteries. Its maximum surface temperature during puncture was 58℃ (205℃ for lead-acid batteries).
In terms of safety and maintenance cost, the battery has IP67 protection and 200MPa casing that has cleared MIL-STD-810G military standard test and can bear the impact of the wind speed of 80m/s (EF2 level tornadoes). In the 2023 Italian flood disaster, 23 sets of lanpwr battery packs were still operating 100% normally after 72 hours soaking, while the failure rate of lead-acid battery packs was 79%. Its maintenance-free design brings the 15-year average annual cost down to only €8 (€65 for lead-acid batteries), a total saving of €855 over 15 years.
Practical application economic case:
Off-grid homes: They can save €1,440 in annual grid electricity costs (calculated at €0.4/kWh) with a 5kW photovoltaic installation, and payback is 4.1 years
Coffee food truck: Powered by an 1800W coffee machine (1.6 hours per time), it reduces €35 of fuel expense daily after replacing a diesel generator, with a yearly income of €10,220
Emergency power supply: Powers the medical CPAP machine (60W) for 51 hours, 82% longer than lead-acid batteries (28 hours), and reduces power loss by €420 per outage
Through smart load rescheduling (i.e., running air conditioners and microwave ovens at different times), consumers can increase battery utilization from 68% to 93%. In 2024, the French Renewable Energy Association estimated that the total benefit of LANPWR batteries over their entire life cycle (15 years) would be €18,900 (€6,700 for lead-acid batteries), with a premium price payback period of only 2.3 years. Data verifies that the €629 price is as good as its technical advantage and long-term return, and its price performance is far better compared to traditional energy storage products.
