image_27.jpeg?189db0Hi Everyone

Last weekend I've tested Panasonic NCR18650B batteries on my maiden PolyClub EPP airplane. 
I was expecting ~40 minutes flight but I landed after 103 minutes 24 seconds! (1h43m24s)

This batteries are definitely working!
Only disadvantage of the batteries are low discharge rate. It is max. 2C.
So, discharge current should be less than 7A for 3400mA NCR18650B

    Great flight.  Love the plane.  Very optimised.

    Thanks, Grant.

  • Thank you folks :)
    @Gary , I want to build a solar quadrocopter from scrap but the sun is only a newsletter name in UK :D
    @RC Tech, LoL, :)

  • Superb stuff Mehil!

    Melih and Vladimir, are you buying your shirts at the same store??

    Simple is best, love it. The multirotor crowd would be wetting their pants at that sort of endurance at such a low cost.

  • Brill I have two of these laying around.

  • 2C = 60min / 2 = 30 minutes

    If you want to fly more than 30min, they are also valuable for you ;)

    Dear Melih. Nice news, you experience a really valuable.

    2S - 7A

    2S2P - 14A

    2S3P - 21A


    But I need a minumum 3S and 30A on take off...
