Here's a fellow in AU with a test of cheap vs expensive solar panels. Turns out the $90 panel puts out significantly more amps than the $300 panel he bought.https://www.youtube.com/watch?v=3-sc4rlV93g Some commenters note the cheap panel is using the newest thing in PV cells. No contact wires across the front to block some light and the face is matt finish instead of gloss so that likely helps absorb more light. But wow, $90 for a 100 watt rated panel. Even if it falls apart after 10 years it's still pretty cheap, especially in a place with high cost per KWH.
Tesla doesn't use lithium polymer, they use lithium ion. In the Model S the pack is chock full of 18650 cells, just like in most laptops that aren't super thin. The Model 3 and Model X are doing things differently. The relatively easy to remove Model S battery is a legacy of when Tesla had plans to build fast battery swap stations, but only built one that was never used. Look up Rich Rebuilds on YouTube. He rebuilt a Model S that spent a week half submerged, used pretty much everything but the body shell from another one that had been rolled. He's rebuilt a second Model S, bought a used Model X (which took Tesla several months to deliver) and while waiting for that one he bought a Model X that was in a flood and is taking it all apart to rebuild. In the middle of all that has been his not so secret "secret" project of transplanting a Model S drivetrain into the back of a Porsche 911. He's not gone ALL electric, he has a Z06 Corvette. Never has said what his regular job is but it has to be pretty good to drop all that coin on Teslas.

I'm not sure there are any wrecked Tesla or Mercedes Hybrids in Australia yet. I could lose a hand in the scrum for the battery or motor. What also scares me about Li-po is what happened to early Dreamliners, smartphones, and a few other gadgets which went up in smoke. _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
