In terms of cycle life and capacity retention capability, lanpwr battery relies on lithium iron phosphate (LiFePO4) technology and can support 5,000 cycles (capacity retention rate ≥80%) under 80% depth of discharge (DoD), far outpacing lead-acid battery’s 300-500 cycles (capacity drops to 50%). Based on a full daily charge and discharge, the lanpwr battery can be used normally for 13.7 years, while lead-acid batteries need to be replaced in 10 months, reducing the long-term holding cost by 72%. For instance, tests conducted by Fraunhofer Institute in Germany in 2023 revealed that at 1,000 consecutive deep cycles, the capacity attenuation rate of lanpwr battery was only 0.03% per cycle, while that of lead-acid batteries was 0.12% per cycle, with a disparity in lifespan of up to four times.
In charging and discharging efficiency, the lanpwr battery supports quick charging and discharging capacity of 1C (100A), with up to 95% charging efficiency (80% for lead-acid battery), and the voltage fluctuation range is controlled within ±1%. For instance, consider the solar off-grid system. A particular customer has a load of 20 kWh per day (DoD 80%). With the use of lanpwr battery, charging time is reduced from 8 hours for lead-acid batteries to 1.5 hours, and average daily rate of energy wastage is reduced from 18% to 3%. Its deep cycling energy conversion efficiency, as per the United States National Renewable Energy Laboratory (NREL) figures, is 92% (75% for lead-acid batteries), and it can discharge another 620 kWh of electricity annually (amounting to a saving of $180 in electricity bills).
As far as cost is concerned, the LCOE of lanpwr battery per kilowatt-hour is $0.03 /kWh (estimated on the basis of 5,000 cycles), and that of lead-acid battery is $0.28 /kWh, and the ROI has increased by 833%. For example, a Californian farm replaced the lanpwr battery-powered irrigation system (1.2 times daily cycle), saving $12,000 over five years in battery replacement and maintenance, and reducing the weight by 55% (100 kg per group vs.) The weight of the lead-acid battery is 220 kg, and the transport energy consumption is reduced by 30%. Furthermore, its modular structure allows for parallel expansion to 40 kWh (with 10 kW maximum power load per group), whereas when lead-acid batteries are paralleled for more than 4 groups, the capacity variation rate is more than 8%, and a further equalizer (25% higher in price) is required.
With regard to security and reliability, the lanpwr battery is certified to UL 1973 and IEC 62619. It also has an intelligent BMS for real-time cell voltage monitoring to ±0.5 mV and temperature gradient (100 Hz sampling frequency). Reduce the possibility of thermal runaway to 0.001% (0.1% risk of acid leakage for lead-acid batteries). In the 2022 Australian bushfire rescue, a medical fleet used lanpwr battery for deep cycling three times a day at a high temperature of 45°C (with a total load of 15 kWh), and no failure was found for 30 consecutive days. However, the lead-acid battery pack failed by sulfation, bringing down 40% of equipment. Its IP67 protection rating and seismic design (MIL-STD-810G compliant) also deliver consistent performance in harsh or wet conditions (90% humidity), with a failure rate of only 0.2 times per thousand hours (1.5 times for lead-acid batteries).
Market empirical facts suggest lanpwr battery wins the deep cycling test conditions. As shown by the 2024 Global Energy Storage Report, its market penetration rate in the solar energy storage market has already hit 64%. Customer feedback shows that based on the assumption of an average daily cycle of 1.5 times, the capacity retention rate is still 79% after five years. For example, in the case of a specific microgrid installation at Fukushima, Japan, lanpwr battery (with an aggregate capacity of 200 kWh) was used to fully charge and discharge every alternate day. After three years of operation, the system energy efficiency error rate was as minimum as 0.8%, while the capacity of the lead-acid battery pack reduced by 47% within the same period.
