Power management board

pixhawk4 power management board got burned down during flight .we are using octacopter kde motors 465kv and 6s 30k tattu battery . is there any solution to this- now we are using a harness but we dont know is it correct way or not
please answer


I think that the reason is power management board can not endure high ampere.
this board can use under 120A

This link is reference of power management board

Sorry i can not write english very well

Hello dear friend
would you please help me on my question?
the question is:

is the mentioned tolerable current (120 A) for each motor on the board or it is the total amount of allowable current

also if we are going to use it for rover, then does each motor power pad on the board, have the capability of passing 120 A of current or not?

Thank you so much
