My jbl charge 4 wont charge but the light blinks.

My jbl charge 4 wont charge but the light blinks.

I tried measuring the amperage when charging, about 0,6 amps, way too low, should be around 2,5 or so, tried a software reset, didn’t work, then i disassembled it, charged the battery with an skyrc Imax and now i have to disassemble the speaker everytime i want to charge it

I saw that the three wires from the charging board to the mainboard were somehow cut, but i couldn’t fix it due to my soldering iron being absent. I dont know the purpose of these wires.

If anyone knows anything about this problem, please let me know.
