Cut the rectangle connector open and found a 560 ohm 1/4 watt resistor inside. Replaced it with a 300 ohm 1/2 watt resistor, which was the closest to 280 I had. Wasn't really a problem fitting the slightly larger resistor. Just carved out a bit more plastic from the molded connector housing and glued it back together. The initial test looked good. But I don't know for sure before I've tested it with the power supply I have at work. It would be nice to be able to read out what kind of power supply the firmware has detected, instead of guessing based on the power drain. Anyone know how to read that from the firmware? Being able to force "rapid charging" off would also be great, if possible. That would allow the use of a misidentified power supply.
