UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)
UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit!
Features
- Designed with an advanced switch mode DC-DC regulator IC.
- Battery polarity reversal protection.
- A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
- The working status is shown by an indicator (LED), which lights when the output is in normal range.
- Output Voltage: [email protected] or [email protected] (Changeable with an output-voltage select jumper)
- Continuous output current: 3 Amps
- Maximum output current: 5 Amps
- Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)

[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!]

As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. Introducing PiJuice! A fully uninterruptible power supply that will always keep your Raspberry Pi powered.
Our revolutionary PiAnywhere technology contained in every PiJuice HAT - is the best way to take your Pi off the grid! The real time clock (RTC) on board will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.
You will be able to always keep track of the charge levels and other info with the two built-in tri-coloured RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with PiJuice.
Keep your Raspberry Pi running with solar, wind and other renewable power.
Ultimate integrated power is one thing but what if we could make the Raspberry Pi renewably powered too? Solar, wind, thermoelectric and other renewable power is free, clean, and green and we're proud to have developed an affordable and efficient renewable power solution for the Raspberry Pi! PiJuice is self-monitoring and, like a space satellite, can become a completely autonomous system. Use the PiJuice as part of an autonomous camera system, weather stations, off-grid desktops, and so many other great outdoor projects. View and buy the solar panels separately.PiJuice Video
