Battery Parameters Visualisation not working in simulation

[dahmanmed]

Dear all,
I used qgroundcontrol with SITL PX4, but during in simulation the value of current always= -1, for that I need to show variation of current consumed and energy consumed in simulation, please can you give relation of energy consumed,

so how can I to work with the current ? what's the solution

That's what @lamping7 's link says - you can't - it isn't supported in simulation. To do this you'd have to modify the simulation itself - some significant work.
The only thing you can do is change the minimum_percentage to simulate low battery (following line after his link).
