That's wrong. kW/s is a meaningless unit - a kilowatt is a unit of power, equal to 1 kilojoule/second, kilojoules are units of energy, and it makes sense to talk about energy per second but not power per second (outside of maybe some weird contexts like how fast you can turn a generator on or off). The figure in Steampunk is for a battery holding 1,872,000,000 kWs - that's kilowatts *times* seconds, not divided by seconds - it's poorly chosen notation apparently intended to avoid having the use Joules anywhere in Vehicles (1 kWs = 1 kJ), and sometimes confused with the plural of kW too - picking kWhr would have been better really.
1,872,000,000 kWs is equal to 520,000 kWhr, which will power its 8000 kW screw propeller for 520,000 kWhr/8000 kW = 65 hours.
