Default Re: 8 volt battery in 6 volt car

Think of using an 8v battery as the 6V components have to run at voltage and power d1ssapation up to 25 % more than they were rated for. Example - the starter spins faster with more power and the bendix smacks into the flywheel with more force - can it take it? Maybe or maybe not, but they were not designed for the extra force.
