Flight endurance test with a Li-ion battery

We test fly a 4S3P battery (build video here : ) on the sub-kilogram Ardupilot folding drone (build video here: )

Li-Ion battery cells are 18650GA cells (3400 mAh) able to provide 10A current continuous discharge, in a 4S3P setup for a total capacity of 10.000 mAh.
This battery, with AWG12 cables/XT60 connector and foam board packaging (thus not optimized for weight reduction) weighs 638 grams (could be optimized down to 600 grams with less tape around it:).

The folding quadcopter, weighing less than a kilogram, embarks a full size Pixhawk1 autopilot with latest Arducopter firmware,  a 3DR telemetry transceiver (433Mhz antenna), a Drotek RTK GPS, a 5.8Ghz FPV Swift cam & 40 channels transmitter.

With 9" props, this ship is way overpowered, hovering at about 30% throttle. When carrying a ZTiny2 3-axis gimbal+Gopro camera, hovering sets right at 50%.
