Portable projectors need to be equipped with high-energy-density lithium polymer batteries to meet the high power consumption requirements of high-definition projection (1080P/4K) and be suitable for outdoor mobile scenarios. The battery should support 2-4 hours of continuous projection, be compatible with fast charging (1C rate) to achieve 80% charging within 1 hour, and reduce the overall weight through lightweight design (<300g) and compact structure. Its wide temperature range adaptability (-10°C~45°C) and overcharge/short circuit protection ensure safe and stable use in various scenarios such as camping and business travel.
