Flashed it with your software, seems to be working. There are 4 lights instead of 1 3 blue and 1 red, so slightly different reporting. After flashing had 8 red blinks charging overcurrent issue, replaced D14, D21, both were not functional.

guess in not done yet the light comes on as if its charging but after several hours checking the voltage with multimeter doe not look like it took any charge. No error blinks. hooked it up to benchtop power supply, no current draw.

seems like there maybe an issue with Q5 MOSFET? looks like it should switch on and off to charge the batties but it seems like its always off? "WK9 85" both Q5 and Q4
