He didn't indicate how the 400 ah were configured. Is it one 12V 400 ah
battery, or one 24v 400 ah battery, etc. But as you noted, once you
convert the battery voltage and amp-hours to watts, it eliminates any
confusion.
If I had 4800 watt-hours of battery (assuming 12V X 4 at 100 amp-hours),
I would estimate 9 hours of run time until the batteries are dead as a
doornail. If you want to use them again (and most people do), then cut
that time in half.
On the other hand, if you have a 48 volt battery with a 400 amp-hour
rating, then you actually have 19,200 watt-hours of capacity, and you
could multiply the above by 4.
If you configure the four 12V/100 ah batteries in series, then you don't
have 400 ah, you have 48V/100 ah. The watt-hours are the same.

watt-hours stay the same - 200x24 and 100x48 both equal 4800 watt
hours. In other words, unless you have some horribly inefficient
voltage converters in the mix, it makes little difference.

How long will 500w load last on 400ah?
