Assuming it's truly double the pumping capacity of the 500GPH pump, it would
not be possible to use less unless the designers of the smaller pump
cleverly installed resistors to increase its power draw. It's also unlikely
to use the same.

I'm betting on more. And probably lots more. Like 2-times more power than
the smaller pump.

However some of that would be offset by the ability to pump faster and be
"on" for a shorter period of time. Even so, your battery had better be ready
to deliver at least double the current (amperage) which also means larger
wires, switches, etc.
