Last weekend I’ve tested Panasonic NCR18650B batteries on my maiden PolyClub EPP airplane.
I was expecting ~40 minutes flight but I landed after 103 minutes 24 seconds! (1h43m24s)
This batteries are definitely working!
Only disadvantage of the batteries are low discharge rate. It is max. 2C.
So, discharge current should be less than 7A for 3400mA NCR18650B
