I think there was a question regarding 12 volt versus using a 16 volt and which was better. Has there been a current check of 12 volt versus 16 for performance? It was my impression that unless you use an alternator the voltage output of a 12 volt was hurting performance if you ran a waterpump, fan, ignition all on one or two 12 volt batteries. The story was a 16 volt battery run down is more actual amperage than a 12 volt fully charged.
#2 If you are WAY over weight then a small battery may be good but.... nothing like two 40 lb batteries in the trunk for ballast AND voltage .
