Turnigy nano-tech v Zippy compact

My friend did a little test for me today to see which battery gave him the best flight times. This wasn't a 100% fair test, as one was a 5000mAh and the other 5800mAh, but interesting results none the less. The frame used for the test was the dji F450 with the Wookong flight controller, RCTimer motors and Graupner 10x5.5 e-props.

Capacity: 5800mAh
Voltage: 4S1P / 4 Cell / 14.8V
Discharge: 25C Constant / 35C Burst
Weight: 569g (including wire, plug & case)
Dimensions: 162x46x34mm
Balance Plug: JST-XH
Discharge Plug: 5.5mm Bullet

V   

Capacity: 5000mAh

Voltage: 4S1P / 4S Cell / 14.8V

Discharge: 35C Constant / 70C Burst

Weight: 531g (including wire, plug & case)

Dimensions: 154x50x33mm

Balance Plug: JST-XH

Discharge Plug: 4mm Bullet-connector

At 569g, the Zippy Compact only weighs a mere 38g more than the nano-tech and is only a few mm longer, yet manages to pack in and extra 800mAh of capacity. More importantly, the Zippy is nearly $10 cheaper than the nano-tech, so presents a significant saving and seemingly excellent value for money, but does it live up to its specs?

Let's have a look!!!

So there you have it, the Zippy compact wins. Ok, I know this wasn't a 100% fair test, but given the lower price, very similar weight and size and the 30% more flight time the Zippy is a clear winner!
