For my robotic projects, I generally use these 5V 1amp dc output power banks to supply power to my arduino and add external power supplies to supply power on the other extra electronic components; otherwise, I always encounter with lot's of energy consumes on the power supply, so the operation time always shortened unless I supply with an usb cable to arduino from my computer.
Other day, I had checking methods for a better way to supply power to arduino to operate my robot with a longer period. Thus, I have some questions about Vin.
I recently bought a new motor controller ( The Actobotics® Dual Motor Controller Assembled Actobotics® Dual Motor Controller - ServoCity) to try from servocity and this is the video how to use it Control Issues - Ep 7: The Actobotics® Dual Motor Controller - YouTube. The person there directly connects the power supply section to arduino's vin and ground and says "More amps better performance" and he is using a 11.1v 5.0 amps lipo battery.
I have 4.0 amps 11.1v and 6.0 amps 11.1v lipo batteries. So, if I supply power from these lipo batteries as connecting them to vin + ground section and if I supply my arduino modules like potentiometers, leds, servo etc, there will be no problem on my arduino itself and on these modules too,right ( without damaging or burning them ) ? thank you very much.
In addition, would you suggest me a nice long lasting power supply bank for Arduino to use please ? I really don't want robot to be stop within 10-15 minutes ( when building a wireless control robot ); because of lack of power. I will be very happy if you assist me about these questions, thank you.
