Hi DJI,

i got a question regarding the Intelligent Flight Battery for the Inspire 1 for better understanding of the software.
What will happen if you fly an Inspire 1 and one cell will drop voltage in flight suddenly while all other cells are ok and the battery still got enough power.

Will the battery cut the power off?
I had a crash some weeks ago, where this happend. The cell that went broken got just 2,5 V in the final stage. When i saw this drop i started to land, but the drone cut the power off OR i killed it with the CSC Command .

Hi Mindy,

i don´t want to open a RMA, i just wanna understand what the Inspire 1 will do, if the voltage drops that much. Can you tell me this to understand the system better and improve safety?

Thank you.

If you read my past posting fall from 26 feet,  I believe my number 3 battery cell  dropped to around 2.6 volts and cut the battery off with no advance notice from the DJI App.

please review my video link.

However I send the drone and camera back to DJI and it was covered under warranty .

They Replaced My Inspire 1 V2 and replaced / Repaired my X5R.

I just ordered the Inspire 2 for the fact of having two batteries , I feel a little more confident I won't fall out the sky again.    Inspire 1 with and X5R camera is now for sale.

That sounds like much the same as my case.
It´s very stuipid from the software side, to cut out the battery for saving it. Its more important to get the drone back on earth, even if the battery is waste after this.

Hi vonganzoben,

I believe that if one cell drops to 3v it will trigger a battery shutdown. As Mario says, it seems daft that the battery will try to protect itself by causing the only thing keeping it aloft, to crash into the Earth. Sone crazt=y logic right there!

I believe it's trying to prevent a battery combustion more than anything while in flight.

Wow! I'm thinking, a battery explosion mid-flight would be way more impressive than a dead bird dropping out the sky.

Yeh dude! Make it explode!

It may be impressive to watch, frightening if the flaming bird was plummeting towards you.
