Raspberry Pi UPS HAT 5V 6A, Supports 4× batteries

DESCRIPTION The Waveshare UPS HAT (E) is an uninterruptible power supply expansion board built for the Raspberry Pi 5, 4B and 3B+, designed to keep your projects running through power outages and brownouts. Ideal for makers, students, and Industry 4.0 edge devices that need reliable, always-on power for the Singapore maker and IoT community. Its standout feature is the bi-directional Type-C fast charging port supporting up to 40W via PD3.0, paired with an onboard fuel gauge IC for real-time battery monitoring over I2C. SAFETY CAUTIONS: Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used. Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery. Do not mix use old batteries with new ones, avoid using batteries of different brands. When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test. Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first. Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
