I use one of these

It is not able to take a ~1kw load like a DPV is capable of pulling so it is not necessarily useful for finding out burn times since it doesn't put enough of a load to get the voltage to drop for battery cutoff, but as @Whitrzac it is definitely enough to check for battery health since you can load test it once a year until the BMS cuts off and track the capacity. Also useful for testing light/heater packs.
 
I may look more into option 1 since that will allow me more flexibility on running the DPV at different speeds for longer periods in a controlled environment. I guess the only downfall is not being able to account for gear factors (doubles + stages) but I can approximate and get some round numbers before a proper in-water test.
As far as the battery is concerned speed 5 has the same current draw no matter what you might be wearing. You'll just go faster in a single vs doubles & stages. The only thing which would change the current draw would be running in air vs water, which you cant do anyway or the shaft seal will burn up.
