Over the years, I've generally made the observation that those who really slam lead acid for energy storage use seem to have been nowhere near a modern lead acid datasheet from the last 20 years, and that seems to be the case here as w

I rebuilt large (500Wh) lithium ebike batteries professionally and shipped them around North America for a couple years, and have torn down more than my fair share of ebike and tool batteries for analysis. I've yet to see a "YouTu

You can insulate them to reduce heating demand, and it will help to an extent (undo that before summer to avoid cooking them), but for an unattended system, it's never going to work out very well. If the system is a year round cabin,

The problem with holes in the ground for storage of things like batteries is that... they're holes in the ground. The ground, as a general guideline, actively dislikes holes in it and strives to fill them in whatever way possible. Li

That's an absolutely absurd characterization of both YouTube and actual teaching. YouTube is dominantly entertainment/personality based "edutainment" at best, based on what seems to percolate to the top and be promoted.

Have you priced LTO? They're rather staggeringly expensive for their capacity. The cycle life is excellent, but they excel in very high C-rate applications (10C-20C), which is the opposite of what you need for off-grid systems. If

I should judge the accuracy of what someone wrote nearly a decade ago by what I think of what I think they believe today? It's a popular enough viewpoint today, certainly, but it leads to throwing out huge swaths of perfectly good work

I've been dealing with an off grid solar office for 5+ years now. Year round power, heating (propane at times, candles/kerosene at others, electricity most of the time if I have the light), and have spent the bulk of this time in

Yes. At least, in some significant ways. I've abandoned smartphones for the time being (but have a PinePhone to hack on for sport and challenge - it in no way resembles a functional device at this point in time) and have gone back to
