Its standard charge-discharge cycle life exceeds 3000 times, with far longer service life than traditional lead-acid batteries under in-depth working conditions. With standardized daily use, it can operate stably for 8 to 10 years, maintaining more than 85% effective capacity after three years of use without cliff-style cruising range decline or sudden power drop. Compared with traditional lead-acid batteries that only have 300 to 500 cycle life and need replacement within 1 to 2 years, this battery pack greatly reduces battery replacement frequency, equipment iteration costs and shutdown work loss, delivering high full-life-cycle cost performance for personal household use, commercial fleets and engineering agricultural applications.

　　Equipped with wide-temperature global adaptation characteristics, it resists high and low temperatures and extreme environments for stable operation in all seasons. Most electric tricycles operate outdoors and exposed to the elements, enduring high-temperature exposure in summer, frost and severe cold in winter, huge day-night temperature differences, as well as rain, snow and wind sand erosion all year round. Ordinary batteries have poor temperature resistance, prone to bulging at high temperatures, power deficit at low temperatures and performance failure. This 72V 180Ah battery pack adopts optimized wide-temperature cell formula and exclusive temperature control structure, achieving excellent global temperature adaptability and stable charge-discharge operation in an ultra-wide temperature range from -20℃ to 60℃. In high-temperature summer environments, the built-in passive heat dissipation structure quickly dissipates operating heat to avoid capacity attenuation, bulging faults and potential safety hazards caused by high-temperature heat accumulation. In severe cold winter environments, the cells maintain high ion activity, effectively alleviating low-temperature capacity shrinkage and weak power performance, and ensuring normal start-up, stable cruising and power output at low temperatures. Meanwhile, the battery has excellent moisture-proof, dust-proof, corrosion-resistant and vibration-resistant properties, adapting to complex working conditions such as muddy farmland, dusty construction sites, rainy wading and bumpy roads with strong environmental adaptability, realizing stable all-season and full-scenario operation regardless of extreme heat, severe cold, sunshine, rain and wind sand.
