Hello everyone. I’m currently having a problem with my mother’s vacuum robot… after 2 1/2 years, the error known to Deebot occurred that the battery is no longer being charged. First worked with all the tricks and tips to get it to load - nothing happens. So I unscrewed it and took a closer look at the mainboard and measured it - it seems that the charge controller is defective and has a short circuit… As soon as the battery is disconnected and the robot is switched on, the controller (Rockchip RK908-1) very hot very quickly. assume that the same controller is responsible for charging the battery. Unfortunately, you can’t get the chips here in Germany, so I have to have them sent to me from China…
Does anyone know the problem, and has possibly already found a solution for it?
