Hi,

Is it possible to avoid PDB failsafe if something wrong happens ? Like, in this way :- Diagram given below

In this diagram the motor/ESC will pull equally from both PDB. If one fails, then the motor/ESC will pull from the remaining one (assuming it is capable of power load). This is assuming the battery is connected to both PDB.

There will be a sensor which senses if the current goes down and will switch to another PDB in case if one fails. The PDB which fails will have no power supply or the voltage will rapidly decrease and if the sensor detects it so it will switch to another PDB.
