The battery system of mobile commercial displays is crucial for their ability to break free from power cords and achieve their "mobile" attribute. It must balance high energy density (supporting 8-14 hours of all-day battery life), wide operating temperature range (-10℃ to 50℃ suitable for outdoor environments), and rapid recharging capability within a compact and lightweight body. Currently, mainstream devices use industrial-grade lithium battery packs, among which lithium iron phosphate batteries are widely used in mobile poster screens due to their high safety and long cycle life (up to 1500 cycles or more).
