Examples: pcb’s in transformers, lead in gasoline. We eventually figured the total costs, due to unaccounted for externalities, were ultimately less if we just stopped using these seemingly cost expedient things.

Elon Musk wrote: “An important consideration that people without a technical background don’t understand is that you can either have a high power or a high energy cell chemistry, but not both.”

Why is that?

I have to say, this was one of by best posts ever, on any chat board in my internet career. I still get a chuckle out of it, two days later, and apparently got a chuckle out of around 39 other folks too. Not only that, but the great Lyle himself replied, which is darn rare (he’s too busy living the electric dream as opposed to 99% of us posers). I didn’t think I could top the monkey thing from a couple months ago, but I did – and by a landslide. I’m awesome. Thanks for listening.

Take a look at the specs on this commodity cell: http://www.evcomponents.com/ProductDetails.asp?ProductCode=SE100AHA

It can handle a 4C 400A drain. The Volts cell (Manganese) can do much more than this cell due to it’s proprietary chemistry of LG. In the close future, commodity cells will be able to match current LG cells. There are other companies with even higher rate cells and there are companies with small very high power cells like this: http://www.all-battery.com/148volt8000mah15c-95ampstickstyle.aspx

So if you want to build a good batt pack for you DIY EV, the Skyenergy cells in the 120-160AH range will do you fine.

Lyle,
After the Cobasys incident it looks like your site has saved us from another terrible debacle! The future looks bright. Maybe bright is not the right word. It’s high amperage from here on!
