Lithium Ion Battery Safety & Cell Voltages
(Lithium Ion cells require more careful handling than normal off the shelf batteries and can be extremely dangerous if mistreated. This can happen by overcharging, overdischarging, physical damage and shorting.
Safe voltage parameters for this type of cell are, unless otherwise stated:
Fully Charged 4.2v – Fully Depleted 2.5 – 3.0v.
The use of a simple Digital MultiMeter is highly advised for periodic checks of the cells and charging equipment performance.)

This reminds me to post something Scaru and i had worked on a while back

The Journal of Alternative Facts TM

"It is critical that there is a credible academic source for the growing and important discipline of alternative facts. This field of study will just keep winning, and we knew that all the best people would want to be on board. There is a real risk in the world today that people might be getting their information about science from actual scientists"

I was thinking,one picture just like the first one,but real scaled leds dimensions.For example,set XM-L(2) as reference size,and increase/decrease size of other leds acorrding to their dimensions relative to xm-l.Or simpler,picture should look exactly like you have all these emmiters on the table and you take pic of them with camera.

Wow! I’m sure there are many folks online who simply don’t grasp how many hours it would take to compile, catalog and post all of that information. For a noob like me, this is an invaluable resource.

Thanks, crx!!
