I replaced a 12 volt battery in my RV (for towing the Spitfire race
car) with two six volt batteries (to get more amp hours/storage) wired
in series to get 12 volts. Question is do I charge it with a 6 volt
or 12 volt charger? Maybe 12 if I hook the charger to where the pos
and neg cables attach.
Thanks
