(only like what happens in your car/bike?) As for it drawing more power than the battery charger is putting in...that will be down to the charging pattern of the charger wont it?

Sorry to quote my self but has any one have any idea about my above question?
Volts and current....and stuff: i understood you can double your volts, but not your current. (thats badly explained)
2 x 12v 40ah batteries in series = 24V 40ah
2 X 12v 40ah batteries in parallel = 12v 80ah
SO.....it will take 450ah PER battery...???
As i said in my first post my two marine batteries at fully charged are not exactly the same voltage...so does that mean there miss-matched? or does it only matter when it comes to charging? (i could charge seem separately?)
