UPS (With RTC & Coulometer) for Raspberry Pi 4B/3B+/3B

Features Independent RTC for timekeeping Current and Voltage Reading through the built-in coulomb counter Battery and charging status LED Indicator Programmable reading of battery voltage via PC Description This UPS board not only supports Raspberry Pi 4B but also adds type C output. It provides enough power for the Raspberry Pi to make your Raspberry Pi still work while moving, and its design is so smart that you can get rid of the trouble of a mass wire. This UPS can provide you with the operation of replacing the battery yourself. This new UPS not only supports an independent RTC module but also provides a coulomb counter.You can obtain battery voltage and current information through I2C in the system. Combined with different programming methods, you can inherit the power information into the system. It is also convenient to detect the state of the battery, which can be detected and warned through the program. It can use most of the 18650 standard batteries and fully comply with the battery characteristics in terms of battery life. In addition, the power display provided on the circuit board is also very user-friendly. The illuminated LED light can quickly show the remaining power and support the discharging while charging. You can directly connect to the external power supply for charging. At the same time, the Raspberry Pi will not be turned off. Attention Please install the battery first, then connect the UPS to the Raspberry Pi.Connecting too many high-power peripherals will lead to an insufficient power supply. Please pay attention to the power demand for peripherals. Danger Please do not reverse the battery! Only for 18650 batteries and the discharge rate should be less than 10A !!! Attention Make sure your power adapter capacity can cover lithium battery charging and raspberry pi use case, typically is 5V 3A or better should be used.
