Tesla battery power

This just a statement so no one jumps in blindly.

The lithium Battery is an awesome battery and has great potential to replace the old lead acid style.
But, do realize, this system is numerous 18650 batteries.
Properly charged and used, they're great! But, and this is important, if one fails, the system does as well.

If you don't know how to detect or how to replace, please don't just jump in.
Educate yourself and learn.
If you can work with these, I see nothing better 'proven' out there.
I'd like to see these types as larger capacity, singular units, at costs we can afford.
I do see it happening.

I consider you all friends. Just my 2cents..
