lithium ion car and motorcycle batteries

Just a smattering of observation in no particular order:

- The reserve capacity in a standard car battery has more to do with the ability to crank the car at very cold temps and when really hot and the engine compression is high... moreso than being able to run anything in normal operation.

No sir. This is not correct. Reserve Capacity, or RC has a standard definition as created by The BCI or Battery Council International.

Reserve Capacity:

"The Battery Council International (BCI) has created a group of standardized specifications that help give consumers an apples to apples comparison from one product to the next. Cold cranking amps is one of those specifications, as is Reserve Capacity. So what is Reserve Capacity? It is a time measurement that explains how long a fully-charged battery can deliver 25 amps of current in an 80°F-environment, before the battery is discharged down to 10.5 volts."

That is the cut and dry definition of reserve capacity.
