In cycle life and energy density, LANPWR Battery achieves 200 Wh/kg energy density through the application of lithium iron phosphate (LiFePO4) technology, 3-4 times the energy density of traditional AGM batteries (50-80 Wh/kg), and its cycle life reaches 5,000 times at 80% depth of discharge (DoD). It is far more than AGM batteries’ 300 to 500 times. For example, for an RV with a 200Ah Battery, when AGM batteries are used, they need to be replaced every two years (the cost of a single group is roughly 600 US dollars), while the 10-year lifespan of LANPWR Battery can reduce the number of replacements by 4, and the total holding cost by 62% (from 2,400 US dollars to 912 US dollars). According to Tesla’s 2023 energy Storage White Paper, the capacity attenuation rate of LiFePO4 batteries is only 0.03% per cycle, while that of AGM batteries is 0.1%. For long-term application, the available capacity of LANPWR batteries is 47% higher than that of AGM batteries.
In efficiency and expense of charging and discharging time, LANPWR Battery supports rapid charging at a rate of up to 1C (0-100% in merely 1 hour) with a 95% charging efficiency, while AGM batteries only support a rate of up to 0.2C (5-8 hours charging) with an 80% efficiency. Take off-grid solar systems as an example, for instance. LANPWR Battery can fully charge 20 kWh during a 4-hour peak sunlight, while the AGM battery will take more than 2 days, leading to an average rate of energy loss per day as high as 15%. The U.S. measured data. Department of Energy in 2022 proves that the discharge efficiency of LANPWR Battery at a low temperature of -20°C is 92%, while that of AGM Battery drops significantly to 35% under the same condition, and the capacity recovery rate is less than 60% (98% for LANPWR Battery).
Cost-benefit analysis shows that although the initial unit price of lanpwr battery (approximately $1,200 /100Ah) is 200% higher than AGM battery ($400 /100Ah), its unit cycle price (based on 5,000 cycles) is only $0.24 /kWh. Much lower than the $1.33 /kWh of AGM batteries, the return on investment (ROI) has been increased by 454%. For example, when a certain shipping company replaced the AGM Battery with lanpwr battery, the annual maintenance cost fell from $3,200 to $200 (down by 93.75%), and due to the 55% reduction in weight (one 100Ah group weighs only 13 kg), the fuel efficiency was increased by 8%. Besides, lanpwr battery may expand modularly in parallel to 40 kWh (the maximal load power is 6 kW for each group), while if over 4 groups of AGM batteries are connected in parallel, the voltage deviation rate exceeds 5%, and an additional equalizer must be installed (cost added by 30%).
In terms of safety and environmental protection, LANPWR Battery has passed UL 1973 certification, and the risk of thermal runaway is less than 0.002% (for AGM batteries, the risk of accidents caused by acid leakage and gas emission hazards is 0.08%). In the 2021 hurricane disaster in Florida, a hospital’s backup power system operated for 72 hours continuously without any glitch with LANPWR Battery under an environmental condition of 95% humidity and 40° C temperature. By comparison, the AGM battery pack suffered 40% failure due to internal sulfation under the same condition. Moreover, LANPWR Battery’s fully enclosed design obviates acid mist pollution (zero VOC emissions) and is EU REACH regulation compliant. The 60% lead content, though, and sulfuric acid electrolyte of AGM batteries require special treatment and recycling (disposal cost: roughly $50 per group).
Market trends confirm that the penetration rate of lithium batteries in the global energy storage market has reached 68% in 2023. Among them, LANPWR Battery occupies 27% of the high-end market share with compatible solar inverters (efficiency 98.5%) and intelligent BMS (SOC accuracy ±1%). According to German TUV report, in the user satisfaction survey, LANPWR Battery surpassed AGM Battery’s 62 points and 48 points respectively in the index of “range stability” and “total holding cost” with 94 points and 89 points respectively, which makes it an inevitable choice for new energy replacement.
