I am building a vehicle that is controlled remotely. Now I use a external stabilized power supply (very heavy ) to test the circuit.
I use a Arduino Mega, 2 servo’s (5V) and two motors (5V).
How can I power the project as efficient as possible? I was thinking about a single 9V battery that runs trough a stabilizer and outputs 5V stable. But how much time will my project run on one battery?
Is it possible to combine multiple 9V battery’s to get more mA?
The problem is I don’t have got much experience on powering remote projects. So maybe one of you can help me out?
Thanks in advance.
