GNB Battery on Eachine X220s

I tested a GNB 1500mAh 4S 110C battery with an Eachine X220s drone. Battery had about 15 take off. This time the temperature was 9°C but i preheated the battery to 22°C. Performance: 16,6 Volt to 6,4 Volt discharge produced 2 minutes and 45 seconds flight time with speed run.
