As far as the battery is concerned, I remember what someone told me. "Volts don't start a truck. Amps do." Is that a good thing to remember? Or BS?
Sorta true. But volts drive the amps down the wires. And resistance anywhere in the circuit impedes the delivery of the amps.
Power = Volts x Amps, and power is really what turns the starter. So you really need both volts AND amps to get the job done.
