"Smallish" and powering the most power hungry Pi there is for 2+ hours are conflicting requirements. Determine (a) how much power the entire set up is using, and (b) how big a battery you are willing to put up with. Calculate the Watt-hours (Wh) required and compare that to the Wh capacity of the battery. Remember to allow for the different voltages involved and losses during voltage conversion.Hey I am making a project that needs a battery but I don't know what to get I need one that is easily rechargeable, can power the Raspberry Pi 5 with an active fan, power a micro OLED screen, etc. I need it to at least do 2 hours of heavy usage but mostly it will be in a stand-by/low-power state. but it also has to be small ish. If I also need another component like a buck converter please let me know. Thank you.
Depending on what you are actually trying to do, you may want to look at using a Pi with lower power requirements.
