Hello,
I am having an issue charging my RC1B for Mavic 2 Pro.  The controller has gone an since December without use.
Currently, when the power button is pressed, the screen lights and and says 0% battery. When plugged in to charge the controller will behave normally, but never show charge past 0%. Controller has been on the charger over 24h with no progression. At some point, the screen will shut off, and stop displaying the charging screen.
However, the controller appears to actually be charging. I can charge other devices from it, and preform multiple flights. The low battery horn blares the whole time though.

Does anybody have a fix, or have experienced similar?

Thank you for your response and we do apologize for the inconvenience. It seems that there is an issue on your remote controller that we cannot troubleshoot remotely. If your remote controller is still within the warranty period, we recommend sending it in for proper diagnostics. You may submit a ticket case at https://repair.dji.com/repair/index but if the unit is no longer under warranty, we recommend you purchase a new one to have a fully functioning unit.
