operating devices on batteries :: which types to you use?

[dhubs]

good evening dear friends,


What has kept me busy lately are questions about operating devices on batteries - i.e. disconnecting things from the mains. What's important here is a good (well planned and well thought out) stable power supply. Fluctuations - these should be avoided if possible.

Batteries - in the power supply, so they play a pretty big role here. For me, the topic of batteries in ?supply? also comes up in Pi projects.
So here's the question: Battery-powered Raspberry Pi projects - what is realistic and what are the limits? How do you manage to keep the application in a stable state with runtimes!?

Background: I feel like more and more DIY enthusiasts who work with the Pi - we use batteries wherever we want to make their Raspberry Pi projects mobile, for example - that is, to go "off-grid". It doesn't matter whether it's about outdoor sensors, a Pi project such as a camera in the garden house or a weather station in the garden house or any other smart gadgets or robotics. Here the battery technology is a "condition-setting" or limiting factor: Questions then arise such as, "What about the running time, charging cycles and efficiency?"

The technical reality at the moment mostly looks like this: are (still) standard, but, I think, new technologies such as LiFePO4 or solid-state batteries could also change the game in the foreseeable future.

I would like to hear your experiences and tips: Which batteries do you use for your mobile projects?
How to optimize battery life for Raspberry Pi applications? Do you also use PV panels if necessary!?

well some of the battery-types i am knowing are the following - see the types of Batteries Suitable for Raspberry Pi

Lithium-ion (Li-ion) or ( on the other handside) Lithium Polymer (LiPo) Batteries
characterized: High energy density, rechargeable

Nickel-Metal Hydride (NiMH) Batteries
characterized: much more robust and safer than Li-ion

Lead-Acid batteries;
characterized - not so expensive and able for high current.

well - the question is - which tiypes are missing here!? Which types would you are ging to use for projects in "off-grid-area"?


look forward to hear from you.

greetings

Off the top about batteries is that moisture is a battery's worst enemy.. Moisture creates perpetual micro-short circuits, perpetually draining the battery, making it work harder all the time.. Somehow batteries must be given a 100% moisture-free, moisture-proof environment to make them last long...
I invented an AC self-charging battery.. The world didn't want it.. They labelled me 'delusional old man', and rejected my offer, so to h with them!..

good evening dear Demanding Truth

thank you so much. Thank you for the answer.

your ideas regarding the moisture-topic is very very good. Thanks for the heads up.
Valid points!! i did not think at the moisture-thing. But this is a important factor.

So i will take al lthe ideas into account - for the project-setup.


Thank you so much for your great great engagement - you are great

You probably should stick to one thread for similar questions. This keeps the discussion all in one place and makes it easier for everyone to follow. Not following my advice... Adafruit has a charge controller with a voltage booster. As suggested in your other thread I would switch to a Pi zero. https://www.circuitbasics.com/how-to...thium-battery/

good day dear Michaelk

thank you for the hint!

thank you for the hint and the heads up to Adafruit - which is generally a awesome ressource - i love it - not only because t hey host the super awesome circuitpython-project ( cf https://circuitpython.org/libraries )

thank you so much - i will follow the link you gave.


dear MichaelK - on a sidenote: I 💕 like 💕 this linux-support-site : its great and gives support on so many levels, and I really enjoy your effective support style. You (and your friends here) support so great!

Keep up your awesome work in the support here - it is definitly a great work
Hats off to you - you and your mates here - you really inspire me!! 😳♥♥♥

and i am glad to be here ....

have a great start in the new week
