However, the specifications of the board from Amazon statePower: 2.1 interface 8-25v DC power supplySo anything between 8 and 25v should be ok, right? So if 4 lithium batteries of 3.7v are used in series, this should work without boost converter? And if a booster module were to be used, am I wrong to think that putting the batteries in series would be beneficial as the voltage is already closer to the target voltage? Or does is this not important/negligible?
