As I'm waiting for my Crees to arrive from Erasmus, I'm pondering what in the heck I'm going to do with them once they arrive :naughty:

I'm thinking that I could buy a 3D mag and drop in 4 Li-ion C cells (with an extension, of course). That should be able to power 4 Q5s with only the addition of a resistor; am I correct in my thinking?

Which leads me to my next question about Lions: Can I use 4 protected cells in this app? Since I won't be charging them as a pack, what charger would you all recommend?

Jumping back to the Q5s and resistors; 3rd shift gave me a great hint about using a dc ampmeter with various resistors to figure out the current draw in a direct drive set up. I think I understand the ohm aspect of a resistor, bur what's the watt rating have to do with the resistance?

Thanks for your time. I hope one day to be able to stop pestering you all...

Stay safe!
