    Grabat claiming 1000 Wh/kg for a new battery type (graphene), that would mean around four times the energy density compared to Lithium.
    That would be roughly 2h fly time for a drone of today's standard if this is true.

    Discussion on HackerNews:
    Energy revolution? Grabat introduces its graphene batteries | Hacker News

    Edit 1:
    A lot of doubt can be found e.g. here:
    Grabat introduces its graphene batteries - certified by TÜV and Dekra - energy density of 1,000 Wh/kg - production mid 2016 • /r/tech

    Edit 2:
    Guy on rcgroups currently testing preproduction samples of graphene batteries for HobbyKing:
    Turnigy Graphene - RC Groups
    I have no idea if this is related in any way.

    All of the above should be taken with a **** load of salt!

    Just read the Russians developed a battery which is nuclear powered and lasting 50 years.

    Turnigy batteries are typically cheaper than others so maybe it will be around $100

    I am working on a solar powered battery. Wing span is about 20 feet. Maximum lift is 165 # so it can carry a small human. Flight time is unknown. Could be years but at least 15 seconds

    Ha. Didn't realize the picture was altered. I saw the original pic years ago and man. They are jacked up.
