I understand all that. SO, in your opinion, do you think their intent was to attenuate voltage/current or this is just a side effect of their protection/detection circuitry?
That's a hard one. Tough to tell what the actual "intent" was. If I were to hazard a guess, I'd say that they came up with the simple algorithm, realized that is was reducing the effective voltage and thus power, and then adjusted the atty resistance (510 days) to match. Done.
But we know that it is not mandatory to design the circuit that way. The Kanger batteries (at least the KR808D-1s that I have tested) don't pulse the power.
