But, it appears that the external power circuit was not designed for the extra power load. So the extra power comes from the batteries when higher loading of the CPUs is used.

The small cores are not overclocked. The big ones are overclocked by 0.2GHz. I doubt that matters. That's just one of the many imperfections of the Pinebook Pro.
is there a way to un-overclock the CPUs?

The quick and dirty way is capping scaling_max_freq https://www.kernel.org/doc/Documentation...-guide.txt

The proper way would be setting non-overclocking core frequencies in the device tree. My Pinebook Pro review (see Website icon below) scratches that (search for rk3399-opp.dtsi)
