The Red Reactor – UPS for any 40 Pin Raspberry Pi Board

Updated: Sep 17


We all know that feeling when suddenly your Raspberry Pi’s MicroSD card get corrupted. It is so frustrating again to setup everything from scratch.


Did you know that one of the leading causes of Data Corruption in Raspberry Pi is unreliable power supply? The Raspberry Pi doesn’t come with an ON/OFF switch.


Building a Raspberry Project that needs to be portable? You will most probably power the Raspberry Pi using a Power Bank. But that too has its limitations. If your Pi Project has a display, several sensors and few USB Devices then a more robust and feature rich Power Supply is a must.


The Red Reactor is a premium feature rich UPS for your Raspberry Pi. No Soldering Needed! The Pogo-pins contact the back side solder joints of the Pi to Deliver Power.

The Red Reactor is not just another battery power supply. Let's look at its features:

  1. Operates with 1 or 2x flat-top 18650 Lithium cells

  2. Provides Accurate Battery Voltage & Current Monitoring over I2C – INA219

  3. Ultra-Low Current Draw when not in use - @<100uA

  4. Normal Use of HAT / 40 Pin Add-ons

  5. As its mounted underneath the Pi, we can use any HAT/40 Pin add-ons

  6. Seamless Switching to Battery, when mains are removed even on High Load

  7. ON Button & Reset Button – Hard Reset by pressing ON for 7 seconds

  8. Over-Charge, Over-Discharge and 6A Over-Current protection

  9. Mounting Holes Designed to Support Pi Models- A+/B+/2B/3A+/3B+/4

  10. Delivers over 4A for a Raspberry Pi, HDD’s, Display and other peripherals

Software Support:


The Red Reactor comes with extensive set of demos, guides and tools.

  • Red Reactor Pi-Battery Widget for Monitoring in Pi OS Desktop

  • Remote Monitoring application server for remote monitoring
