18650 New UPS With RTC function Power Supply Device for Raspberry Pi 4 B/3B+/3B

Description

New UPS With RTC &
Coulometer
Pro Power Supply Device
The new version of UPS with RTC function was updated on April 30!
Product Description
This is a new version of UPS Board.It 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 troubled 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 remain 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.
Please install the battery first, then connect the UPS to the Raspberry Pi.
Connecting too many high-power peripherals will lead to insufficient power supply. Please pay attention to the power demand of peripherals.
[Caution - Warning!]
Warning!
Please do not reverse the battery!
This product belongs to the power supply device.
Please keep it out of the reach of children. Please strictly refer to the instructions for the UPS product. If the battery polarity is reversed, it will directly burn the power management chip of the device and even cause fire or personal injury. Do not add any Components by yourself, all accidental damage caused by the cause is at your own risk.
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.
(ex:Battery charge may require up to 2.1A, Raspberry Pi typically requires 0.6-0.8A, but up to 2.4A, at which if the power supply current is less than 4.5A, it may not be able to continue use)
ESD Warning
When connecting the battery, please do not touch the area where the yellow frame is located. ESD may cause damage to your device, so please avoid it.
