    Its seems a lot of us want to know how to DIY bat mod or where to get it done!
    With these popular chats and brags of the excellent fpvlr & itelite antennas, the next upgrade would be to battery mod your bird to use these antennas to there full potential!
    I havent been able to dig up u-tube vids or images of how to's! Could we use this thread to share whats involved in the install, how to use the xtra batteries, and any info that may help the curiosities of a subject that seems to pop up a lot in antenna & long distance conversations.i know i personally would already have done this mod if i knew more about it.

    I haven't seen the inside of my drone so I can't say for certain what the mod consists of. I run nano tech 1300's for tray batteries.

    There's a positive and negative terminal when you take off the top, you can solder direct to that.

    I was wondering if you could just solder the external battery leads to the point where the P3 battery wires are soldered to the main battery "blades" that the internal battery plugs into. Looks to be pretty accessible to me.

    I'd like a little more info. before I try this myself.

    Is there a technical reason that 4c 1000/1300 mah bats are used not a couple 2200's or is all about weight

    I think the 1000's and 1300 4s batteries are optimum for capacity vs weight*
    *Turnigy Nano-Tech 4s 45-90c battery weight:

    The 1000 4s 124g
    The 1300 4s 155g
    The 2200 4s 257g

    Personally, I think the 1000 4s bats are the best compromise. And remember, these weights are for each battery...you need two if you're going to use a dual battery mod.

    Turn the stock battery on then the lipo packs when your done flying disconnect the lipo packs then turn off the stock battery.
