First flight completed with the Rekon 6 LR and the new Zop Power 14.8v 4S 3400mah Li-ion pack… and the results are in 
Details of the quad / set up and some flight footage here:
I was getting pretty much 9mins on a 4S 1500mah Li-Po so was v. interested to see what this one could achieve.
Flight time, without GoPro and cruising at 50-60kph most of the time, was… nineteen minutes! 
Was genuinely unsure how well this was going to work - so I’ll take that!
I was just cruising and it flew really smoothly, didn’t really hammer the throttle at all (not that kind of test!) I did punch it a couple of times and it certainly had enough to react snappily.
I set battery warning to 3.1v per cell and min v to 3.0v. I’ve seen some folks take it down to 2.5v, but then others say that’s too low and is a bit sketchy. I landed at 12.2v and it immediately recovered to 12.9-13.0v. Battery was only very slightly warm - and motors were completely cool. 
The battery itself is clearly 4 x 18650 cells… but is labelled as Li-Po?! I charged as a Li-ion with my balance charger and all is spot on. It will be interesting to see what the longevity of this one is. I’ll also do another test carrying the GoPro and post results in this thread. I’d very much class this one as a mountain climber now… can’t wait to find some proper scenery to go exploring. 
…I’d say 8, comfortably.
