more expensive, better built (copper plates!), powerful,

my THOUGHTS / FINDINGS:
iFlight 8000mah intentionally mislabeled as 4500mah because of shipping and/or transportation in carry on...
Does it make sense to go full in with an 890g battery?
Yes, if you need max flight time and more wind resistance ;)
"diminishing returns" compared to using the UE 5000mah botgrinder pack with its high density? - Kind of...
UE 5Ah pack gave me 21mins and a more agile flight feeling!
iFlight pack 26mins and higher VOLTs during the whole flight (2P config!)
FILGHTTIME longterm experience
- longterm averages using my Chimera7 with Farinpack:
avg. 11:30mins with Chim7 (and mostly Gopro) where 14mins was max calculated FT ~250mah/min
- compared to LipoHV 5cell and 4000mah Lipo which I also used a lot:
avg. 11:18mins with Chim7 (and gopro) also 14mins max calc FT
- Foxeer Aura7 (lower system weight, no gopro because DJI O3 - max flighttime!)
~ 26min with 8Ah iFlight, wo gopro! But real flying not just gentle laps!
~ 21min with 5ah UpgradeEnergy
