Enclosure & Battery Kit for Raspberry Pi Boards Sells for $22

The easiest solution to power Raspberry Pi boards from batteries is to use a USB power bank, and if you want a neater solution, PiJuice HAT board is quite nice, but for something a little cheaper and available right now, Geekworm’s RPi PowerPack kit could be an interesting option with an acrylic enclosure, a battery board with a 3,800 mAh Lithium battery, a fan, three heatsinks, as well as a micro USB to USB cable.

Complete kit, Raspberry Pi Board not Included

Key features of RPi PowerPack board:

  • 3,800 mAh Lithium battery good for around 9 hours on the Raspberry Pi 3.
  • Output current – 1.8A
  • Output voltage: 5.1V ± 0.1V
  • USB – 2x USB output port
  • Standard charging current / voltage – 1.0A/5.0V via 1x micro USB port.
  • Misc – On/Off switch (The battery still charges in off position)

  1. Same kit but with Raspberry Pi 3 board included for $65 -> 8http://www.dx.com/p/raspberry-pi-3-battery-board-case-fan-heatsink-usb-cable-kit-435048?Utm_rid=93072394&Utm_source=affiliate, so that probably means the battery is really part of the board.

    Nope, no UPS mode possible since for UPS useage knowing battery capacity is a basic requirement and not possible here. You could only try to watch for voltage drops to trigger an emergency shutdown but if the step-up converters on the board always provide 5.1V until battery is empty this won’t work too. If you don’t know you’re running on battery you can not react.

    Small ARM server + UPS == Allwinner A20 board 😉

    With Olimex A20 Lime2 boards by simply attaching a 3.7V battery you get an UPS solution that also powers a connected 2.5″ SATA disk. And in Armbian we provide many ways to monitor battery use with both legacy and mainline kernel (see eg. this thread here)

  3. @onebir
    A list of A20 devices is here http://linux-sunxi.org/Category:A20_Boards

    Most of them feature a battery connector or solder pads but the only boards providing step-up converters to also power a connected 2.5″ disk when running on battery are Olimex’ Lime/Lime2 and Lamobo R1 (which has so many design flaws that I wouldn’t recommend it). With a Banana Pi or Pro for example you would’ve to take 5V from the board’s USB ports to get ‘UPS mode’ for a disk (confirmed to work, you find several threads in LeMaker forum)

  4. “With Olimex A20 Lime2 boards by simply attaching a 3.7V battery” => beaglebone also integrates a PMIC, which makes it easy to connect a li-po battery https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2013/08/10/bbb–rechargeable-on-board-battery-system

    “The kit is sold for $22.43” => can’t the ~same thing be achieved with a <1$ usb-lipo charger such as http://www.aliexpress.com/item/TP4056-1A-Lipo-Battery-Charging-Board-Charger-Module-lithium-battery-DIY-Mini-USB-Port-Free-shipping/1567407584.html ?

  5. You can just buy a cheap power bank with power “pass-thru” (or build one yourself) and connect a 5-3.3V regulator to the input of the bank (mains). The input can be safely fed to the SBC. A simple script monitors the GPIO pin and sets up a countdown timer to shut down the SBC safely before the bank drains. Simple and reliable.

    There are different kinds of UPS.
    My UPS does not communicate at all with my computer, but when there’s a power failure it does the job, and I can manually turn off the computer. I agree that for server / gateway use, it’s much better for the system to know when it’s running on battery, and when it should automatically turn off and turn on in order to preserve data.

    Nice trick to use Ethernet to detect power outage. Battery level is obviously estimated, not measured here, so you need to make some tests and assumption to evaluate the battery life.

  8. Do you know where I can find a similar acrylic case (UK or EU would be nice), where I can stack 3 or more Raspberry Pi?

  9. @cnxsoft
    Ah – thanks. A fixed time seems could be problematic in some cases, eg if power fails repeatedly before the battery can fully recharge…

  10. @onebir
    Can’t we find a work around for that like e.g to do checks for uptime (cron) and somehow try to reduce it?

    I mean this is a very simple and good idea that guy came up with 🙂

  11. @fossxplorer
    Sure – wouldn’t be hard to model battery charge & usage approximately with constants. Then allow a big margin for error. But I don’t know C, so better left to someone who does 🙂

  12. @fossxplorer
    Would a software eqvivalent of a egg timer work, where number goes down when Ethernet off but builds up to set top limit when Ethernet on. Crude but would work, just needs adjusting to represent real charge time?

    @onebir only just seen your post on posting mine.

  13. Thank you for link
    but only charge this battery even if the switch is turned off, I think powerbank is better and sample.
