@ottaross I believe you're wise in the ways of electronics? I've got a project with a solar panel delivering 6W, 5V output and I want to charge 6 x 3.7V 18650 batteries in parallel (not series). I want overcharge and overdischarge protection. I've seen plenty of these (see link) but nothing for the number of cells I want to use. They are all for one cell. Those that can do multiple cells always seem to assume the batteries are in series.
@ottaross It will probably take time to source the LTO batteries that I want, so I might start with some Lithium Ion batteries for when it's warmer then upgrade later.
I should add that I've only been there for a few days and this is my first impression. There's some fun stuff too, I have to say, including an Alf meme and copious booty pics. But still a bit self-obsessed. Maybe it needs time to germinate the more interesting stuff that I take for granted here.
