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. The 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. Key Features Uninterruptible Power – Seamless switchover between external and battery power 5V 2.5A Output – Stable regulated output via ETA1188 voltage regulator I2C Battery Monitoring – Real-time voltage, current, power, and capacity readings (INA219) Comprehensive Protection – Overcharge, over-discharge, overcurrent, short-circuit, and reverse-polarity protection Equalising Charge – Balances battery cells for safer, more stable operation Dual Charging/Discharging Methods – Via solder pads (5V 3A in / 5V 2.5A out) or pin headers Status Indicators – Power, charging, and reverse-connection warning LEDs Boot Button – Battery activation switch Onboard Components ETA1188 – 5V voltage regulator ETA6953 – Battery charge/discharge controller INA219 – Voltage/current monitoring IC S8261 – Battery protection IC RT9193 – 3.3V voltage regulator AO4402 – Battery protection MOSFET LED Indicators Power LED – On when UPS output is enabled Charge LED – On: charging · Blinking: battery abnormal or not connected · Off: complete or not charging Reverse Warning LEDs – On if a battery is connected with reversed polarity Note: 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. Battery 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.
