This upgraded 20Ah lithium battery for Citycoco is equipped with an integrated protection module. Customized for off-road Harley electric scooters, it builds a multi-layer protection system adapting to bumpy rides, rainy days and electromagnetic interference. It effectively solves common problems such as circuit dampness, vibration desoldering and external impact damage. With a zonal integrated layout, it divides electrical, physical and environmental protection units to jointly protect internal cells and circuit components, suitable for urban commuting, outdoor off-roading and short-distance travel.

　　The electrical protection module adopts a high-precision control chip with six-fold protection including overvoltage, overcurrent, short circuit, overheating, reverse connection and overdischarge. It cuts off power within milliseconds during abnormal conditions to avoid circuit burnout. The built-in voltage stabilization unit filters electromagnetic clutter, suppresses current fluctuation and prevents controller failure caused by unstable voltage.

　　The shockproof physical structure with flexible buffer layers fixes internal components firmly to prevent wire loosening and cell displacement. The IP65 waterproof sealed structure blocks rain, sediment and moisture to avoid metal oxidation. Equipped with an anti-freezing protection unit, it optimizes low-temperature discharge logic to prevent cell damage in cold weather. Highly compatible with all Citycoco models without wire modification, the multi-protection module improves durability and safety while reducing failure rates, providing all-round reliable safety guarantees for Citycoco electric scooters.
