The nominal capacity of 2560Wh of lanpwr batterie (actual available energy ≥2350Wh, conversion efficiency 92%) is equivalent to 2.56 kilowatt-hours. Calculated at the standard voltage of 51.2V, its charge storage capacity reaches 180,000 coulomb. This energy can keep a 100W LED light illuminated continuously for 25.6 hours or charge a smart phone (with an average battery capacity of 12Wh) 213 times. Compared with the Tesla Powerwall 13.5kWh system, a single lanpwr batterie can supply power to a household basic load (150W for the refrigerator + 10W for the router) for 14 hours.
The energy density reaches 185Wh/kg (volumetric energy density 420Wh/L), which is 362% higher than that of lead-acid batteries (40Wh/kg). Under the standard test environment of 25℃±2℃, discharging at a rate of 0.2C (current 50A) can release 100% of the nominal capacity. If discharged at a rate of 1C (current 250A), the actual output energy still reaches 2430Wh (efficiency 95%). Tests by TUV Rheinland in 2023 showed that this battery still retained 82% of its energy in a low-temperature environment of -20℃ (the industry average was 65%).
The practical application verifies the energy value. A certain outdoor data center adopted 20 sets of lanpwr batterie (with a total capacity of 51.2kWh). After being disconnected from the power grid, it supported the operation of 5 servers (each with a power consumption of 800W) for 6.4 hours, reducing the usage of diesel generators by 38 liters (reducing CO₂ emissions by 100kg). Referring to the case of the 2024 German Photovoltaic Exhibition, a household photovoltaic system paired with lanpwr batterie can store 4.2kWh of photovoltaic surplus (equivalent to the daily power generation of 3.5 square meters of solar panels) through daily charge and discharge cycles, saving 1,270 euros in electricity fees annually.
The charge and discharge loss rate is industry-leading. After 2,000 deep cycles (DoD of 80%), the capacity retention rate of lanpwr batterie is > 80% (70% as required by the national standard GB/T 36276), and the calendar life reaches 10 years. Its BMS system keeps the self-discharge rate at 3% per month (20% for lead-acid batteries), and the energy retention rate still exceeds 90% after being idle for one year. BloombergNEF data indicates that the charge and discharge efficiency of LiFePO₄ batteries (92-95%) is 5 percentage points higher than that of NMC batteries (85-90%).
The cost-benefit ratio is significant. Based on the residential electricity price of 0.6 yuan /kWh in China, a single lanpwr batterie can transfer 15,360kWh of electrical energy throughout its full life cycle (6,000 cycles), valued at 9,216 yuan, with a cost per kilowatt-hour of only 0.03 yuan (0.5 yuan for lead-acid batteries). Under the time-of-use electricity price policy in California (with a peak-valley price difference of $0.4 /kWh), users can earn $1.02 per day through lanpwr batterie energy storage arbitrage, and the investment payback period is shortened to 3.2 years.
