It's a really nice voltage with lots of support for batteries and up/dn conversion hardware.

It's also right at the edge of what is human safe. You can burn yourself and blow up cables, but it's very difficult to electrocute yourself (afib or muscle seize) without lots of wet contact.

Indeed, I'm aware of only one recorded death by electrocution at 48V, iirc it was a Swiss radio amateur that had done a bunch of gardening sat down sweaty in a metallic chair and reached for the one switch of his set. Probably there were other contributory causes as well, I've been zapped multiple times from much higher voltage sources (that could have easily supplied the power required) and lived.

I can't find a reference for that Swiss case though. I'll keep looking.

I assume if you didn’t live from those zaps you wouldn’t be here making this comment.

Haha, fair point, yes, indeed. The most clear form of survivorship bias, thank you for pointing it out.
