The summary of this project is a kitchen/camping mini coffee grinder so it is small and portable.

1-The battery i've decided to use is a 11.1v lithium polymer battery with a USB for continuous power from an AC source.

2-The motor I currently have is a 12v. (Do I need a 11.1v motor for it to last longer.

3-Also there is a LED push button switch that takes some power.

My main concerns:

-Does it need capacitors (from stalling when blade is hitting coffee beans), resistors, MOFSET's?

-I want the battery to last atleast 1 hour ( the motor I have draws 2A.)

Thank you, don't hesitate to ask as many questions as needed.

Regards,

Sean
