This is probably a stupid question:
I'm confused on charging 6 volt deep cycle batteries that are in series= 12v . OK I get that the two 6 volt batteries need to be in series,,,what good is 6 volts these days? So they are used and re charged as 12 volts,,I get that.
Round numbers, say one of the 6 volt batteries is 200 amp hour rating. You hook 2 in series and the amp hours stay the same and voltage doubles ?
So you still have 200 amp hours?
You discharge them 80%. 80% of your 200 amp hours. This is where I get lost: So now you have discharged 160 amp hours? But you started out with two 6 volt
batteries, so why haven't you discharged 320,,160 from each battery ? Or another way to look at it, if you had one big 12 volt battery rated @ 200 amp hour and discharged it 80%, would the single 12v take less time to re charge than the two 6 volt batteries that are in series?
