I have a lot of respect for your opinions though we often differ but you are out over your skis here and claiming a better STEM education only makes it worse.

The 18650 cells you see today are potentially quite different from the cells of 20 years ago. Just because they have the same standardized external dimensions it is foolish to think they are the same inside which is patently false. The 18650 standard has been around for almost 30 years. During that time the maximum capacity has more than tripled from 1200 mAh to as much as 4000 mAh today, cycle times have increased significantly, and max discharge rates have risen from under 5A to as much as 40A. There are literally dozens of combinations of capacity and discharge rates available today along with widely varied pricing and quality. This has been accomplished by tweaking the chemistry and construction of the cells despite the basic chemistry staying the same.

Your statement was dead wrong and I actually think you know it and were just preaching to a choir that doesn't know better. All current 18650 cells are not the same and definitely not all are remotely similar to cells of 20 years ago though you can still buy low capacity low discharge rate cells because they are cheaper and completely adequate in some applications.

I have no issue with people who dislike EVs for whatever reason but misinformation whether accidental or purposeful needs to be addressed.

Of course he knows it, Clames is a known liar/troll. Either that or he's a serious headcase.

How anyone can look around at all of the battery powered equipment today and say with a straight face that the technology hasn't advanced in 20 years is beyond me. They weren't making battery powered chainsaws and mowers and snowblowers 20 years ago, but they are now because shite is better. They weren't making battery powered concrete finishing tools 20 years ago but they are now because shite is better.

And drones existed but they weren't as cheap and ubiquitous as today because shite got better. Batteries and motors deliver more punch in a smaller and lighter package.

But the chemistry is the same! The limitations!

Blah blah blah, take a look around.

And while you're at it, run it by me again, Clames, how your disaster plan which relies on the international oil trade and mega-corp refineries and transport infrastructure and banks and the internet to all continue functioning is better than an off-grid-capable battery+solar+EV plan which only requires the sun to rise each day?
