QuadroPower 6200mAh (4s) RC Lipo Battery - Flat

Fits and works perfect in the LiPo holder that comes with the Okto2 kit. Having that shape leaves extra space for a medium size gimbal. This battery gave me 20mins to 25mins of slow flying on the Okto2 with the first 15 flights. I recommend having some kind of telemetry to control the battery stats while flying, even if its for training.

My hexa 2 work perfect almost 20-minute flight with gopro2! now new lipo!!!

Have about 25 flights on two of these packs. We see internal resistance values of about 1.2 to 2 milli ohms. We use the LIPo Figure of Merit calculator to keep track of battery health. Based on these calculations the Quadropower batteries always have better figures of merit than cheaper brands.
