thanks sir for the info. 300 hours. Any time limit connected to the 300 hours how many years is this?
Its 12 months for any problems what so ever. Looking to extend it out more as we get some more data in.

I’ve noticed in the photo with the throttle screen that you consumed 4.6kwh from the 4.8kwh battery. I’m suprised that it was possible.
I thought that we need to stop when there are about 20-25% left for the life of the battery. At least that’s what I see people are doing.
Is that your every time practice or just that time?
I think that when people say 20-25% they’re working that out based on the voltage. There’s a minimum cell voltage below which you’re not meant to go or you’ll start to do irreversible damage to the battery.
As @Pdwhite mentioned earlier in this thread:
if you are trying to maintain and get the maximum life out of your battery pack then I wouldn’t go below zero but it’s not a big deal if you do as there is a bit of a buffer. The cells are rated to go down to 2.7V per cell but we like to have plenty of margin.
Once on the ground the cells were all in the 3.27-3.37V range (see pic) so I don’t think I need to be too concerned.
This was the only time I’ve flown the 4.8kWh battery until cutoff so far.
