Awesome device

For LiFePO4wered/Pi3

I failed to review this sooner due to not creating an actual account. The device works wonderfully as a Raspberry Pi UPS, and has done so through many brown/blackouts.

Nathaniel | June 18, 2024

Item is great, seller is fantastic

For LiFePO4wered/Pi+

I ordered this to use as a UPS for an older Raspberry Pi. I had ordered an older model several years ago and was happy with that. I encountered a couple of issues during my implementation that the seller helped me with in a very prompt and friendly manner. Highly recommend

Mareks | March 13, 2023

Just works

For wESP32-Prog

I tried to find something that does exact thing, but with no luck. Finally I found it. Would be nice to have type-c instead of micro.

Jay | Jan. 8, 2023

Great product

For wESP32

I bought a handful of these to use with ESPHome.

The hardware is exceptional, documentation is good. I was really impressed with the low power consumption relative to other similar products. I'm measuring less than half of the power consumption via my managed PoE switch.

Don | Nov. 8, 2022

Perfect Solution !

For wESP32-Prog

Easy way to implement programming for my board without adding the cost to each board. Would highly recommend.

Cody | Aug. 6, 2022

Excellent

For PoE-FeatherWing

Great "featherwing"! PoE is very underrated, especially for IIOT where WiFi and LoRa aren't feasible. PoE without an ugly splitter involved is simply bliss. Please keep them coming!

Farley | Nov. 23, 2021

Received and functional, thanks!

For LiFePO4wered/Pi+

Received promptly despite international shipping. Been playing with it for a day now, software and hardware seems to work great. Thanks!

Great Product, Very Much Worth It

For LiFePO4wered/Pi+

I bought this product to use for my Raspberry Pi 4 Car Head Unit. I needed a UPS to power off the Pi after it loses power from my car when I turn the car off. My interest in this product was the fact that it can withstand such high and low temperatures because it will be out in my car throughout all the seasons. I would consider myself a beginner on the verge of intermediate Pi user and I had absolutely no trouble reading and using the documentation to set up this UPS to suit my specific needs. This UPS works exactly as advertised and the documentation is verbose yet clear. If you're still trying to decide whether this product is worth it, it is. So, thank you to the creators of this product. If I ever need a UPS for any other outdoor projects, I will certainly be buying this again. Thank you guys for creating this!

Well-engineered board from a professional

For wESP32

My wESP32 arrived promptly in a very well-packaged envelope. Patrick has quality documentation, has detailed information about his work, and is responsive to messages online. Quality sample code is provided, and I'm excited to put this to use, and hopefully purchase more in the future.

Justin | May 26, 2021

Excellent product

For LiFePO4wered/Pi+

I love this thing. I considered many different UPS solutions, but really this one was the best “overall package”. The command line interface is neat, easy, and informative.

I use it on a pi4, which is not really supported due to the greater power draw. I haven’t scientifically stress tested it to see just how long it would last, but I once noticed it lasted at least 20 mins. That said, it works great for switching between my anker battery and wall wart.

Only critique I have is that I wish the input power was USB-C instead of micro USB so that I could use only one type of plug.

Maikel | May 5, 2021

Really awesome product that very reliable

For LiFePO4wered/Pi+

I have years of experience with the previous version that protected my Linux driven music player for around 4 years. It’s highly customizable with settings
This new version has a bunch more horse power and has even more R&D in it so I’m fully confident it will work like a charm
Thanks for this amazing UPS Patrick
Cheers Maikel

Dianne | April 28, 2021

works perfectly despite my best efforts

For LiFePO4wered/Pi+

I needed something that would shut down the raspi about 5 minutes after the power was cut. It's for a car computer that's powered off the switched cigarette lighter. when the lighter comes on, the pi comes on, when it goes off, the pi goes off after whatever time i want. it takes up to 20 volts and works good with solar. I've tried many of these, this one is flawless. This board and A123 LiFe cells are my go-to now for safe and reliable power.

Shawn | Oct. 23, 2020

Finally a proper solution to a common problem.

For LiFePO4wered/Pi+

It seems like such a simple problem, and yet nobody else has this solution? A true online ups for an SBC with a battery that enjoys UPS operations. I'll probably buy one every time I purchase an RPi or other SBC. I had previously tried to implement a True Online UPS using LIPOs for my Pocket Beagles, but that did not work out well. I was very disappointed. But through persistence, I stumbled across this.

Allen | Sept. 9, 2020

.Wonderfully executed

For LiFePO4wered/Pi+

Exactly what I was looking for and more. Very flexible and configurable. Lots of thought went into all the different use-cases and are supported out of the box.

Christopher | March 30, 2020

Board works great!

For wESP32 bargains!

The board works great as an ESP32 Ethernet development platform. I'm currently powering it from the USB port with the USB Prog board, so I can't speak to the POE performance yet. The seller was responsive to questions that I had, replying within a day.

John | June 24, 2019

Nice form factor for ESP32 devices

For LiFePO4wered/USB

I used it to power the example cam server on an ESP32-CAM board (wireless connection). For some reason I am picking up random interference on the video when its plugged into the LiFePO4 battery pack that I don't see when using the USB power from my desktop. I am happy with concept here...I just need to figure out where this interference is coming from.

Response from Silicognition LLC | June 24, 2019

Hi John,

Thanks for the feedback. Do you have plenty of decoupling capacitance on the power supply? Usually a large value bulk cap and some smaller 0.1uF and 1nF in parallel right by the power supply pins is a good way to cover all frequencies. The bulk cap (try 100uF) may be needed to absorb the instantaneous current demands.
Also, the ESP32-CAM is powered with 5V through the voltage regulator when plugged into USB. If you connect the LiFePO4wered/USB, it will only provide 3.2V battery voltage, and if this goes through a linear regulator, it's unlikely the system gets the required voltage. The LiFePO4wered/USB works best when powering 3V circuits directly without regulator.

Matthias | Jan. 11, 2019

Nice one!

For LiFePO4wered/Solar1

We just brought our first Solar1 to life, it just works as assumed! We're running two LiFePo4 2.5A batteries in parallel. Thus we ordered just 5V/1A-heating-pads we're running two of these in series (and hope that our solar current (20W/18V panel) won't exceed (2x5V)/(2x1A) while we're still under 0°C :).

If you a ready for some german or an automated translation, you can see our project-documentation on our "autonomous cell - solar-airparticle-weather-comparething"[0] or see some live-data within a grafana-dashboard[1].

Wow, nice build! Impressive Matthias! :)

Radim | Nov. 27, 2018

It works!

For LiFePO4wered/Pi3

Perfect product
Perfect design
Perfect quality
Perfect API
PERFECT!

It works on my RPi for about a year now without any problems and it saved my dataloging three times during power outages.

Excellent MPP Solar Charger for LiFePO4 batteries

For LiFePO4wered/Solar1

This is the BEST liFePO4 solar charger on the market! Most (if not all!) other options available have poor performance, built quality and/or do not use MPP battery charging. The LiFePO4wered/Solar charge controller is compact, flexible, built from the ground up for this amazing battery technology. While there are other reasonable solutions for house-sized LiFePO4 power packs, this project provides a professional solution for small and mid-sized projects. We are currently testing this in the field at a major SE University and the charging profile and performance are excellent.

Scott | May 6, 2018

Does everything I wanted and more.

For LiFePO4wered/Pi3

I'm using this to make a pi media server for the car and when travelling. It does a lovely job and allows me to have a completely portable setup with no in car modifications required.

Gary | May 3, 2018

Suitable only for limited applications

For LiFePO4wered/Pi3

Pro:
Functions well as a true UPS.
Documentation is good.
Customer service is good.

Con:
The optional Stackable 40-pin Header uses non-compliant pins (not 0.025" sq), which cannot be trusted to connect reliably with normal mating connectors.
The specified current capacity of 0.85 amps seems too low for the price of the product.

Zarul Bakri | May 3, 2018

fast delivery

For LiFePO4wered/Pi

Tq for fast delivery, this things use for student using for project., i just supply the Lifepo to them.

Patrick | April 10, 2018

Perfect!

For LiFePO4wered/Pi3

Works together with Razberry, I‘ happy with the ups! Documentation is easy for unterstanding and also suitable for beginners

Angel Carlos | Feb. 28, 2018

Highly recommended product

For LiFePO4wered/Pi3

It works great, although I'm a rookie, the installation was successful.
UPS properly and allows me to shut down without damaging files.
What more can you ask for? Now I can do projects that keep the system up in spite of power outages.
Thank you very much

Stephen | Feb. 21, 2018

Love it, no problems at all

For LiFePO4wered/USB

Works perfectly, this is the easiest drop-in battery power supply for breadboarding and microcontroller projects that I've found so far. Virtually everything else uses Li-Ion, which I didn't want, or is designed as a Raspberry Pi hat, or isn't available anymore.

Because there are pins on the bottom of the battery holder PCB, you can just drop it on to the power line rows on the edge of a solderless breadboard and not worry about having a power supply nearby all the time. And you could easily push them through a normal breadboard or PCB and solder them in place as well.

Thanks for making these :)

Konstantinos | Feb. 13, 2018

Good product bad support

For LiFePO4wered/Pi3

Very satisfied with the product which works as described. However, upon reconnecting the Sense HAT it burnt it. I contacted support to ask whether this is a known behaviour. Never received a response.

Response from Silicognition LLC | Feb. 13, 2018

Hello Konstantinos,
I pride myself in providing excellent support, as most customers can confirm. In your case, I replied to your email from Jan 31 on the same day. Please check your spam folder. Most customers will also try the Tindie forums before leaving a negative review. I respond promptly to both.

David | Dec. 22, 2017

Works as advertised

For LiFePO4wered/Pi3

Excellent product, no surprise, no effort. Almost plug and play.
I got 2h20 of autonomy on a headless Pi3 doing light duty network tasks.
As of feature suggestion, I believe it should not be that difficult to build-in a RTC clock for when the Pi is powered off.
Also, the capacitive button with the LED is cool, but I prefer a standard click button, I'm a bit old school.

Cash | Dec. 18, 2017

The LifePO4wered/Pi3 works perfectly, excellent product!

For LiFePO4wered/Pi3

I have to say that this is an extremely mature and well designed unit. I have needed it for development testing and it works exactly as advertised and in fact has handled a bit of abuse without much complaining. The designed did a great job of putting out a "pro-consumer" class piece of hardware and I look forward to his next iterations of the device. It is a great idea, well executed and a great example of small business executing better than the big guys.

Highly recommended for you Pi or similar SBC's.

Kathia | Dec. 12, 2017

Kathia,

I don't know if it was your intention, but a review is not the right place for this. You are sharing personal information with the whole world since this is public.

According to the tracking information, as of right now the package is still in transit. This is still a normal amount of time for international shipping. Most likely your package is held at customs in your country and you are expected to pay duties to have it released. Please contact your local customs office to check if this is the case.

Well designed, good software support

For LiFePO4wered/Pi

Great product, well designed. Thank you for making it.
I am using this UPS for Raspberry Pi Zero W in headless mode. With auto_boot option there is no need for the button press, and it works as expected without any intervention. Using wireless does consume more power, but I have not measured the current so I am not sure if it could deplete the battery faster than it's being charged. Using this in Python so I had to write a little CLI wrapper that uses subprocess.
Some features that would be nice to have:
- current monitoring (like MAX44286)
- battery capacity calculation
- Python module (not CLI wrapper)
- option to solder +5V in
-option to solder the LiFePo cell or use a cell with tabs
- a version of the product as a kit of 4 components: 2 pcbs, battery holder, header - this leaves flexibility to meet space constraints that some people have, use different battery size / with tabs.

The best PI UPS for me, so far...

For LiFePO4wered/Pi3

My main interest in having a Raspberry Pi UPS was for my seventeen year old robot, Pogo, but first the LiFeP04wered/Pi3 is under test to protect my robot development Pi from much-too-regular power utility outages.

While I am away from my desk, I leave my robot development Raspberry Pi 3 running the distributed computing platform BOINC with Einstein@Home and SETI@Home tasks crunching.

This crunching draws about 0.7A at 5.4v at the wall-wart before installing the LiFePO4wered/Pi3 UPS. Since this is below the 0.85A load limit of the LiFePO4wered/Pi3 UPS, there is no electrical problem to support this.

I purchased the LiFePO4wered/Pi3 UPS with the cool transparent blue case, and added some "Self adhesive Clear Door Knob Bumpers. 0.5 inch thick - 0.9 inch diameter" feet to give better air flow, and an Adafruit 15x15x15mm heatsink over the CPU, and a small sink over the LAN chip.

With BOINC preferences set for three cores, 66% of processor time, 80% of memory, vcgencmd reports temps between 72-78 degC, and no throttling.

Under normal operation, this Pi UPS is doing a great job. I did recommend the addition of a "long press to force off" feature for the unusual case where the Pi aborted unexpectedly leaving not way to cycle the power.

Ned | July 17, 2017

Excellent piece of hardware; installs and works flawlessly

For LiFePO4wered/Pi3

After several mishaps where a Raspberry Pi containing important data ended up with a corrupted filesystem, I decided to add this combination UPS/shutdown-startup-control module. Installation was trivial and so was setup - download the software, build, install, done.

The documentation is a little on the terse side but everything you really need is there. (Tip: If a CLI command returns -1 you've probably forgotten to run it as root/with sudo.) I needed to set exactly one parameter (auto_boot) to something other than the default.

Paul | July 6, 2017

A nicely designed, easy to use backup power supply

For LiFePO4wered/Pi3

This is well engineered backup power supply for the Raspberry Pi 3. Reading through the documentation I could see a lot of thought has gone into the design from battery selection through to the command-line tools to control the device. I'd tried a similar product before this one, but found that one had poor documentation and was hard to get going. The LiFePO4wered/Pi3 is really excellent.
