The honda manual output chart shows 12.4 volts at 2000rpm (just about reaching parity with a reasonable battery) which could be interpreted as "switch on point" as the rpm is producing output that can charge a low battery.
Specifies 14.5 volts @ 4000rpm to reach full output.
Also 13.2 volts @ 3000rpm, not a huge amount over a decent battery.
You can see the gradient from that, and why low rpm accompanying high draw would leave the battery depleted.
