Sounds like you mostly figured it out. Just email the logs to yourself and then use this website to get human readable output:

That usually works.
Had a new development this past Saturday.
I had returned home from work (my employer has deemed me essential) & plugged the bike in to charge & instead of hearing the Contactor pull in & the green charge light illuminating, the High Temperature warning light was flashing.
I tried Turing the key on/off, unplugging/plugging the power back in but no change.
I configured the “A” on the dash for error codes & found the following..
8 (Hi Batt Temp)
11 (Batt Temp 2nd Stg)
25 (Contactor Open Warning)
45 (Kickstand Switch Disable)
47 (MBB Charger Connected Disable)
48 (Sevcon Start Up Disable)
49 (Contactor Open Disable)
Never saw #10 (Batt Temp Warning 1st Stg)
At one point, the motor temperature reading would fluctuate with 1031f displayed at least twice. For the most part it did reflect a more realistic value of 118f.
Eventually the faults went away & normal operation was restored & charging commenced.
I downloaded the logs & see lots of recent abnormally high entries, but nothing about High Battery Temperature.
I’m guessing it’s an anomaly that will once again rear it’s ugly head
