The thermal component? To reduce charge current if the pack overheats . . . .
And I believe that on the "green component" that both parties may be partially correct. My understanding is that JR built the packs for the US market with the picofuse in them, and for the rest of the world with a diode to prevent reverse polarity charging. So, what you have, I think, depends a bit on where you are located . . . and where you bought the radio . . .
