Kingsong S18 won’t turn on

[nullptr]

Have an S18 with ~1900 miles, no major crashes and I only ride in good weather conditions. Has worked great since purchasing new, including yesterday after a normal commute ride. The battery charged normally and the wheel turned on and was balancing normally.

After it charged up, I sat on the wheel to compress the suspension so I could check the air pressure, and 20 seconds after sitting on the wheel it stopped balancing. It no longer turns on. When I press the power button, the light turns on (and stays on for as long as the button is depressed). The charging circuitry seems normal (charger detects that the battery is full). No Bluetooth connection.

Any theories or tips on debugging?

if you keep the power button depressed does the bluetooth come back on? if it does see if you can update the firmware?

No -- the front light stays on for as long as the button is depressed, but it doesn't turn on on the unit, so no access to firmware / etc. It is essentially a very heavy flashlight at the moment!

its possible you blown a fuse, i believe there's multiple fuses in the S18, and motherboard and each battery pack has one
