Is this a battery failure?

Hey just wanted to post that my spark fell from 100. This was my 31 flight, 3rd for the day, and i realized later, after i sent it in for repair that  this was the first time i flew on the battery. Which i had ordered a week after ordering the fly more combo. I was 2 mins into my flight in sport mode, really loving it, and i came to a stop about 15 feet in front of me but a 100 ft up and all of a sudden it shutoff and flew to the ground. Causing the battery to blow out and two of the props to come off. But the airframe looked good, but it gave me all kind of errors, esc errors, no gps. So i setup a refresh case and sent it in. The package arrived on friday to dji service center. But I'm  now thinking that it could of been a failure of the new battery? I dont know but it seems like a manufacturing error and I'm hoping that the repair service can figure this out, because I don't know how I'm going to trust this spark if they say it was user error! I was in a wide open field with low wind and it drops to the ground.
Nelow is one of my reddit post with the battery serial #:

Holy moly, I just checked to see which battery I was using and it was my brand new battery, this was the first time I used the battery and it was only 2 mins in to the flight. Looks like I need to update my service record. Battery sn 0C0AE6CB32004Y. I GUESS IF YOU GET A NEW BATTERY FLY LOW to test it out!

Hey Mindy,
thanks for looking into this. my Case # CAS-779083-V0M1S0
This was my 31 flight with the spark and it was about 2min 30 sec into the flight. First flight with the new battery.  My flight data ends with no stick commands and only audio recording. Video cutout (on the phone and SD card about 15 seconds before it hit the ground. pretty sure it was still recording as it was falling because you can hear me cuss. I couldn't believe it! the last set of flights were over a lake so I'm glad I could recover it on this flight. Hopefully there is more data on board of the spark.

I've checked the case that the drone was just received, it will conduct damage assessment and then the data analysis.
We will analyze the reason about the crash and if it's malfunction, your drone will be repaired or replaced without any charge according to DJI After-Sales Policy. No worries. Appreciate your patience.

Not sure if this two thread is related, my Spark Controller got disconnected during the flight today, I wasn't flying high so my aircraft as safe.
When I came across to below thread and got the controller fixed.

Later I came across this thread and realize I was using a new battery I just got from DJI Store (Causeway Bay Hong Kong ) today.
Could this possibly be a battery problem causing my RC to disconnected?

Hi, I was the one wrote those thread about battery.
That cannot say for sure, your remote disconnect could also because the weak signal, or interference.

Also, please note that what do you meant by "disconnect", sometimes, the phone screen show aircraft disconnect, but that is only between phone and the remote, you can still control the aircraft with the remote. If that is the case, you are fine, try using a quality cable, and OTG adapter to connect between phone and remote.

If you really lost the connection between the remote and aircraft, it will activate RTH after 3 second. If that is the case, please try plug in the new battery, connect to DJI Assistant 2 on PC, re-run the firmware with thta battery.
Then, make sure you have bluetooth off on your phone.  Fly again to see if the problem fixed or not.

If not, please contact DJI support for further assistant. I just gave advice based on my experience so far.
