> That would work out to 1.2kWH weighing what I guess to be about 40 pounds in batteries alone.
Absolutely not. Sony VTC4s are early 2010s cells that do 30 amps continuous with 2000 mAh capacity[1]. 172 cells weigh in at 17 lbs, 1.2 kWh, and a whopping 16.5 kW continuous rated output.
For lower power applications, higher-capacity cells like the NCR18650G[2] weigh below 10 lbs per kWh.
