iOS does have this appreciated feature now, for newer devices at least.

I actually bought a (very cheap) soldering iron today just for this, haha. Ironically I probably last owned one about the time I should have fixed this the first time. There's a little bit of technique to it but once you get it down it's not hard to do a functional job!

Nice! My efforts weren't so comprehensive this time, but now that I went to this effort I'm trying to resist the urge to completely change the configuration of one or two of my others :p

It is a 2004 Ibanez RG1570, slightly modified :)

Really looking forward to this album. The new single took me back to listening to the 9.11 album for the first time 23 years ago, all over again. Can't wait to hear it, and can't wait to completely fail at learning to play the songs!

Really interesting work. Shall make a point to read both in more detail!

I fully endorse this, as I'm sure you guessed :)
The description of Wh/kg on single electrode/material level for example bothers me no end. Since it is always calculated using a potential, which of course is vs a reference, it should be Wh/kg vs something

In your line of work I assume you've seen it all!

I had a brief scroll on 'X' for old times' sake recently. Top of the lists were Trump and Musk tweets, followed by some conspiracy theories, a couple of flat earther videos, crypto, AI generated slop, some Hitler worship, maybe 1 post in 100 worth reading. Let it rot

I've seen something similar before. Also possible to short cans over longer distance with many series connected cells between. Then you get a higher voltage spark with lots of power, enough to locally heat materials to very high temp and start thermal runaway, even if shorting terminals does nothing

Assuming I'm reading it right, it checks out - if two cell cans in series stack come into contact and they're not isolated then one cell will short. A number of ways to minimise that though now. Didn't they use to market these as not able to catch fire?

I'm curious about the cycle life too. All the real data I've ever seen (likely outdated now) doesn't indicate great cycle life (and much worse calendar life) but spec sheets suggest almost on par with LFP. Interested to know if there is real data or just unverifiable numbers
