I'm happy to discuss the topic in earnest?
Well, after doing some research on several batteries, it appears the average RC (Reserve Capacity) is about 60 minutes.

So, even if the FR-S battery was half that, the engine would overheat, due to the water pump not running, before the battery would run out of juice.

So, there ........ @Tcoat was WRONG !.........
