48v30ah lithium battery
The 48V30Ah lithium battery is a mainstream large-capacity supporting power supply for two-wheel electric commuter vehicles, light-duty freight electric vehicles, small sightseeing equipment and low-speed intelligent machinery. With moderate capacity, stable power and wide adaptability, it has become the core power supply device for daily civilian commuting, short-distance distribution and park operation scenarios. For most ordinary 48V lithium batteries after long-term use, the most common failure is not cell attenuation, but secondary faults caused by sealing structure failure. Conventional batteries on the market mostly adopt low-cost ordinary rubber strips and recycled rubber sealing auxiliary materials. After long-term exposure to sunlight, alternating high and low temperatures, rain erosion and vehicle bump vibration, the sealing strips are prone to hardening, cracking, shrinking, degumming and powder aging, directly leading to battery water ingress, moisture accumulation, dust
