Four 18650 cells from power tool batteries - Vruzend end caps and nickel strips - and a USB power bank PCB from eBay.
NOTE: This power bank PCB charges the cells to over 4.3V - I don't recommend it.

Interesting… I might get one of those Li-Ion battery block sets if I can (whatever they're called) as it would be better for my requirements than soldering Li-Ion cells together (don't have a spot welder).
What's the model No. of the Ryobi tek4 digital multi meter? and where can I get one From?
Wow those battery holders are expensive and shipping is half of what the cost of the components are.
awww you left us with a cliffhanger 🙂
My experience with USB power banks of the DIY and "with Type C port" variety so far is: You need to put a charge in before it really turns on (bank dependent, it varies, my 2nd one didn't I think) and they absolutely need a full charge and drain (0%-/100%-0%) to train them on the capacity. The first one I got gave it a 0% capacity with 12 hours left on a 4w draw and after the charge, drain, and charge it was accurate to within 2-3% since the batteries are high cap (and I doubt it was expecting that).
I LOVE the Type-C QC class power banks since it takes a 12-16 hr charge on my 28Ah pack down to 5-6 hr charge. The micro-b power bank takes 8-12 hours for (at this point from use and age) probably 16-18Ah capacity.
If your Type-C board doesn't allow power out it's definitely hamstrung by half on usefulness. It doesn't appear to support QC or any similar charge type at all, sadly. For the price though it's good. (mine was, with 8-cell case, 16 shipped)
Order the top chip on the datasheet and get out the hot air 🙂
Can you make more videos on the Z80?? 😀
Got unskippable orange king advertisement just letting you know youtube has been shoving this crap down our throats hope we vote him out so we stop getting this crap. But love the video
Buy every pre build part on some online store, solder 2 wires together aaand… its done! Modern diy videos
lovely video – thank you
Where did you get the blue and red holders
