PI-JUICE
#1
I am very new to this but has anyone used a pi-juice hat to control the shutdown? I just got one and so far it seems to be a good shutdown solution. It has it's own microprocessor and monitors it's own onboard battery. It has settings that will shut down the pi at a percentage that you can set. The battery that comes with it keeps my pi and touch screen running for about 2 hours.

If you like the results then stick with it.

sounds interesting. maybe take up less space.
when you shut your car off, do you have a script that shuts off the pi after a few minutes?

never heard of this but i'm extremely interested. Does this automatically handle shutdown duties? I have a graceful shutdown option installed, but every time i update OAP I have to reconfigure it.

This is the web site. https://uk.pi-supply.com/products/pijuice-standard
I got mine here. https://www.ebay.com/itm/PiJuice-HAT/223588500557?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
I don't have a script for the shut down other than the operation that is built into the pi-juice.

so currently when you shut off the car, does it just stay on until the battery dies?
When you start the car, does it automatically startup?

Right now I am shutting it down before I leave, however, I don't have to wait to shut the car off. When I start the car the pi starts up. There are settings that I haven't yet explored where I won't have to manually shut it down.

I would not use this unless you live somewhere cold.

Lithium ion batteries are not designed for use in harsh environments like the inside of a car baking in the sun.
The label on the battery actually reads "do not expose to high temperature (140F/60C)". Take into account that it's sitting above a rpi that's already generating enough heat of its own.

I would instead look at a super-capacitor solution if you really want an onboard UPS.

Well I live in Washington. It doesn't get very hot or cold here, just wet. I do plan to have a cooling fan.
