Until NHRA realizes that it just isn't safe because of that among other reasons maybe they will finally let us move the other battery to the back .
Last time I brought that up though I received some death threats and powder laced letters in the mail lol..But hey we got roller rockers now so everyone is much safer now and all is good.

Whenever the topic of dual batteries comes up, series and parallel get mixed up. Series is wired + to - and doubles the voltage. Parallel is wired + to + and doubles the amperage. Parallel makes two 12 volt batteries into one big strong 12 volt battery. Never wire 12 volts in series in a race car.
