Greetings,
New to the forum. New to the Raspberry Pi. I have read every post here and elsewhere on this but I am still a bit confused on the topic.
I am a software engineer by trade, but electrical engineer, I am fairly ignorant.
I have an idea I would like prototyping, but I need my unit to be portable and ideally semi compact (think, not a car battery).
I understand many like to choose to utilize a powertool battery to achieve this goal, but I am having a difficult time understanding which size I should start with. Now you will probably want to know how long it needs to run for and under what type of load. Again, I am just at the idea stage here. I guess I would just estimate conservatively I would like it to run in a semi idle mode for at least 4 hours, and be under heavy load (max CPU and ram utilization for 30 minutes). This would be running headless, with maybe a microphone and a speaker added at some point down the line. So first question? What battery should I start with?
I also understand I will need a buck converter. Perhaps someone could recommend one of these as well?
Now I don't know if I need anything else, like a UPS, or some have mentioned discharge protection module.
Thanks for reading,
Alex
