I have to admit I’m a bit disappointed. I was hoping to see a real, full-size car battery.
I actually have three absorbent glass mat batteries hooked up to a Noco Genius battery tender and a 1000W 12V inverter to provide battery backup for my sump pumps (long story). Losslessly converting that to 5V shouldn’t be too hard.
