Testing out some Lipo batteries on this one. Please keep in mind that these are just my results and they only include overall power output. There are lots of other thing that go into lipos. Check out flitetest's review for different details on lipo's. I did charge each lipo to the proper 4.2v per cell on a calibrated charger prior to testing. Here are the links to the parts involved in this video.

  • Why do people use prop motoers not edf fans!!??

  • @nzRCreviews Props are almost always better. EDF's can be fun and they give you the look of jets but they are notoriously inefficient. Props give you far more instant thrust and less power consumption.

  • Yeah, those nano's are a rare breed. Put them in your wish list and they will email you when stock comes in.

  • A different way of looking at this would be to stress the packs to what they are rated for. 2.2ah(20c)=44amps etc.. Then see how much voltage they can hold under different incremental loads on them.

    Say you have the 2.2ah 20c pack. Measure how much voltage it holds at 11a, 22a,33a, and 44a.

    I hope you can follow what im saying. Just that voltage drop under load is what we need to know. we want to go vertical without worrying about lipo cuttoff kicking in!

    Keep up the good work :)

  • @Brushlessboy16 You're right on about getting exact performance numbers. I was simply showing how the C rating will actually effect your performance. I am trying to walk the line between giving too much technical data that most can't follow it and dumbing down my videos. You're absolutely right about the proper testing for technical figures. These nano's are just a great deal and can keep the amps flowing under high stress better than others I have seen. Thanks for the comment!

  • you neglected to mention that higher C rating comes at cost of more mass. why have capability for X watts wherr you only need max of 0.5x watts?

  • És erre időt szánsz barom.....

  • You are standing in the propellers' plane of rotation....

  • What it does show is that the internal resistance of the Nanotech is less than the others. You dont even state what the sustained voltage or power is, only the peek.

  • great real world test, need more of this type test.

    Kudos to you sir

  • Hey, good review.

    I just wanted to add that the test only tests using a motor that wants to pull around 240W, and varies based on the voltag

    The nanotech hold's it's voltage a little better, which explains the 10W extra that the motor pulled, due to the higher voltage.

    If you were to connect it to a system that actually tried pulling 100A, the nanotech would show it's ability to output 45C, the others would obviously fail, 20C, 25C...

    The test wouldn't be fair to the other batteries.

  • МОТОР ? MOTOR?

  • Great vid and info! Thanks
