This that total amp draw or just amp draw?

How did you setup for current draw? We need more details.

mAh draw to see how many used from the battery

And i install follow the wiring manual

TBS crossfire is set to TX 5 / RX 5

In betaflight default Uart 5 is set to Serial RX, and I dont need to choose TBS SmartAudio and my receiver is connected, and can read quad battery voltage and RQLY

Mah drawn is total mah you used. So it will continue to go up. Current draw is what current you are pulling at the moment.

In your other tread, you haven't indicated how you are wiring for current.

Fc, vtx + camera make the mAh drawn keep running, but in the video you posted I think its running to fast, maybe the current scale it's not correctly configured in betaflight

I've been looking your other post and I think that your pdb doesn't have a current sensor, so I think that you can't have info of the mAh drawn

Is this one your pdb? http://www.mateksys.com/?portfolio=pdb-xt60

If your ESC has ESC telemetry, you can wire to RX4 for current telemetry. You can also buy a pigtail with current sensor.

That looks normal. The mAh draw looks a little fast but that is subjective. You may just have a lot of LED's or your VTX may be on full power... any number of things. 

Does your battery last as long as you think it should? If it does then you're fine.
