I feel this question should have an obviously simple answer however my brain isn’t working well this week!! Say I have 2 x 100 Ah 12 volt batteries. I know the Watt hours contained in them are the same whether I series or parallel them but the voltage and Amperage changes, so far so good.. The thing that is confusing me is the Ah CAPACITY. To run something longer we need more capacity? But if I series the batteries I only get 100 Ah and parallel 200?

But does voltage come into play as Well? If I have two identical 100 Watt loads but one is 24 volt and the other 12 volts would they both run for the same time if hooked up to the correct corresponding voltages using those two batteries I mentioned earlier?

The 24 volt load has half the capacity but more voltage, the 12 volt load has double the capacity but less volts, they both have the same Watt hours available though.

Im leaning towards they both will run the same?

Thanks,

Steve
