Hi Greatscott I would like to ask you if you know how to make a 4S1P battery pack out of 18650 batteries to be used in a RC Plane so it has to have a balance lead to the batteries and leads for the motor if you know how to do it can you PLEASE let me know and a little drawing would be GREAT Thank You

It's pretty easy. Connect those cells in series ( - of first battery to + of the second one, - of second one to the + of the third one and so on ). Then, solder red wire to the positive contact of the pack and the black one to the negative. Balance leads go from + of the first, second and third cell ( 4th + terminal is + of the whole pack connected to the red cable mentioned before ). Balance leads can be thin, but the power ones should have big gauge ( depending on the current needs ).

Hi,Scott

Can you make a project how to make a mahanic arm from DC motors and can you visit my youtube channel.THANKS!!!

Mahanic arm? Something like that still doesn't exist... Did you mean a mechanical arm?

If yes, I'm pretty sure servo's could work...

i mean a mechanical arm.Thanks for the correction

Do you mean an articulated arm that moves up and down with DC motors?

You'd need gears to do that, since most DC motors spin way too fast. How big would you make it? I think something small could be powered by servo's, but nything bigger than that probably would be easy to make :)

i really wish to see u making a Laser Engraver / Cutter using the laser u got from the DVD driver
keep up the great work

Hi Scott,

I've seen people request videos for you videos on your YouTube channel, And I have one too:

"Electronics Basics: Transformer Power Supplies vs. Switched Power Supplies"

It would be awesome if you make it!

GreatScottLab (author)  Yonatan244 months ago

I put it on my to do list.

Awesome! Thanks!

"Electronics Basics: Brushed vs. Brushless Motors" Would be awesome too

You have the best electronics tutorials on Earth, Seriously!
