I only know what it says on the Tindie Pi-UPS site.
I haven`t bought one.
Multiple Pi`s connected would demand multiples of the 750 mA limit which is on
offer, if that is what you infer.
The text suggests that these units can be stacked to provide more hours for a
single Pi board.
Also, the Redundant Power Hat (Hogwarts?).....
http://alchemy-power.com/pi-bb-rps/ will only power one Pi at a time, but ;
can take all sorts of DC inputs.
It has a large breadboard surface .
Maybe a high current source with fan-out to feed each Pi could be realised
on this breadboard.

Can you use the UPS with a Raspberry Pi Cluster?
I know that if done. It would need a larger battery than the 450mah that comes
with the basic one.
If its possible. What all would need to be done as far as configuration?
Chuck?

Ermmmm. I think that the UPS has a simple voltage detector which signals
one of the GPIO of the Pi. The Pi will have to generate an alarm based on
this . The UPS is in the form of a Pi Shield, eg a small board which docks
with the GPIO fingers.
Maybe it is in the code element offered with this kit.
Hope this helps. I just Googled Pi UPS and this seemed good. This is the
one hour version, there is a heavier grade item also on offer.
I discussed this earlier this year with mikey11 , maybe he has words
of wisdom.

Hi John,
This is exactly what I want. However, I have a touch screen connected to my
raspberry pi 3. I can connect this device via the micro USB port but will I
still get the battery information?

What about
https://www.tindie.com/products/pkawas/pi-zero-uptime-ups-for-pi-in-pi-zero-
size-2/
Which is a kind of Pi-wart eg a side shield with a standby battery.
Good text explanatory.

Hi all,
I am looking for a compact raspberry pi ups. I did buy one but it turned out
to be a battery pack. I want something that will alert me if the battery
goes too low. Does such an animal exist or do I need to create one?
