Jump-starting a car with a battery pack

How am I supposed to charge two 100Ah batteries on a charger within the 10-hour window of off-peak hours?
Even if you assume losses are only 50% of the difference between peak and off-peak rates—meaning a 25% gain, though it’s likely much worse—you might save a few bucks a day. But you'd need pro-level gear to make it work: high-quality batteries, a solid inverter, and a heavy-duty charger (over 20A), which isn't exactly something you want using to blast your batteries at those levels.
