From the material and certification perspective, lanpwr battery has received dual certifications of UL 1973 (Energy Storage Systems Safety Standard) and IEC 62619 (International Specification for Industrial Lithium Batteries) and its thermal runaway risk is less than 0.002% (industry average is 0.1%). For instance, according to the 2023 Tesla Energy Accident Analysis Report, similar lithium iron phosphate (LiFePO4) technology products experience a thermal runaway rate of only 0.005% when operating at high temperatures (60°C), but lanpwr battery reduces the risk by an additional 60% through multi-layer ceramic separators and liquid cooling technology. Apart from that, its case is made of V-0 grade fire-proof material (combustion self-extinguishing time <3 seconds), and IP67 waterproof and dustproof has been passed. It can even be submerged in a 1-meter deep water for 30 minutes, and will be in good condition under severe outdoor conditions such as heavy rain (falling precipitation ≥50 mm/h) or sand and dust (particle density ≤1500 μg/m³).
In terms of environmental adaptability, lanpwr battery can work between -20°C and 60°C, and it is still capable of providing 92% discharge efficiency in low temperatures (-10°C) (the capacity of lead-acid batteries will reduce to 40% at the same time). According to the data of the Norwegian Arctic Circle solar energy storage project, in the winter test of 2022, lanpwr battery maintained a constant average daily output power of 9.8 kWh (nominal capacity of 10 kWh) in an ambient of -15°C for 30 days continuously with only ±1.5% deviation in capacity. Inside buildings, its noise when running is less than 25 dB (A-weighted), 70% quieter than typical diesel generators (85 dB), and emits zero toxic gases (with CO and NOx emissions both at 0 ppm) to meet the United States Environmental Protection Agency (EPA) indoor air quality standards.
Under the design aspect of protection safety, lanpwr battery has a intelligent BMS system which can monitor in real time voltage fluctuations (accuracy ±0.5 mV), temperature differentials (sample rate 100 Hz), and current abnormalities (response time <2 ms), and automatically disconnect the faulty unit. For instance, during the 2021 flooding of Germany, the lanpwr battery used in an outdoor emergency base station did not fail after 48 hours underwater with a failure rate of only 0.3 times per thousand hours. During the same period, the danger of fire caused by short circuits in lead-acid battery packs was as high as 1.2%. Apart from this, its seismic performance has also been certified through MIL-STD-810G. During the 5 magnitude earthquake test (at a 5.5 m/s² acceleration), the deformation rate of the structure is less than 0.1%, far below the industry safety requirement (1%).
Practical cases and market experience are able to prove that lanpwr battery is steadily operational both indoors and outdoors. According to 2023 Global Energy Storage Safety Database (ESSD) figures, its cumulative deployment quantity has surpassed 120,000 units with only 0.0045% accident rate (industry average 0.03%). For example, since a residential photovoltaic system in California changed to lanpwr battery, there has been no maintenance fee for three consecutive years (the average annual maintenance fee of traditional systems is about 200 US dollars) and charging and discharging efficiency has always been above 95% (the average annual attenuation rate of lead-acid batteries is 8%). In the outdoor condition, when the Amazon Rainforest research team used this battery-powered device (with a 3 kW load power), the cycle life remained as high as 4,500 times (the nominal value is 5,000 times) under a humidity condition of 90%, and the performance loss rate was less than 10%.
