When external power is connected, it charges the batteries while providing a stable 5V output. If external power is lost, it automatically switches to battery power without interruption — keeping your system running.\n\nThe module communicates over I2C (via an onboard INA219), allowing real-time monitoring of battery voltage, current, power, and remaining capacity. It is designed for easy integration into mobile robots, embedded systems, and industrial control applications.\n\nKey Features\n\n\nUninterruptible Power – Seamless switchover between external and battery power\n\n5V 2.5A Output – Stable regulated output via ETA1188 voltage regulator\n\nI2C Battery Monitoring – Real-time voltage, current, power, and capacity readings (INA219)\n\nComprehensive Protection – Overcharge, over-discharge, overcurrent, short-circuit, and reverse-polarity protection\n\nEqualising Charge – Balances battery cells for safer, more stable operation\n\nDual Charging/Discharging Methods – Via solder pads (5V 3A in / 5V 2.5A out) or pin headers\n\nStatus Indicators – Power, charging, and reverse-connection warning LEDs\n\nBoot Button – Battery activation switch\n\n\nOnboard Components\n\n\nETA1188 – 5V voltage regulator\n\nETA6953 – Battery charge/discharge controller\n\nINA219 – Voltage/current monitoring IC\n\nS8261 – Battery protection IC\n\nRT9193 – 3.3V voltage regulator\n\nAO4402 – Battery protection MOSFET\n\n\nLED Indicators\n\n\nPower LED – On when UPS output is enabled\n\nCharge LED – On: charging · Blinking: battery abnormal or not connected · Off: complete or not charging\n\nReverse Warning LEDs – On if a battery is connected with reversed polarity\n\n\n\nNote: When using pin headers for charging and discharging, connect all input and output pins to distribute the 2.5A output current and reduce pin stress. Batteries (10440 Li-ion) are not included.\n\n\n\nBattery Safety: Li-ion batteries can cause fire, injury, or property damage if improperly used. Do not reverse polarity. Do not mix old and new batteries or different brands. Use only compatible batteries from reputable manufacturers. Replace batteries when they reach their rated cycle life or after two years, whichever comes first. Keep away from children and flammable materials.\n\n\nIdeal For\n\nRaspberry Pi and Compute Module backup power\nMobile robotics and embedded systems\nIndustrial control and IoT devices\n\n\nPackage Contents\n\n1× UPS Module Mini\n\n\nResources\n\nProduct Wiki\n","vendor":"Waveshare","product_type":"","in_stock":true,"options":[],"variants":[{"id":1374,"title":"Default Title","sku":"WS-24760","price":30.94,"on_sale":false,"in_stock":true,"available_quantity":11,"option1":"Default Title"}]}
