I am doing a project with GoPiGo and I want to use 8 AA Rechargeable Ni-Cad Batteries (1.2V) instead of the 8 AA Non - Rechargeable battery. My concern is the voltage will be 1.2V*8 = 9.6V when the batteries are full charged, but it will soon drop down to below 9V.
So anyone here use the Ni-Cad Rechargeable battery for GoPiGo? Is this fine? How long it can last? Do I need to use some circuit to step-up the voltage?
Thanks a lot.
