Silicone wire - measured and tested
We measured the performance of Silicone wire, gauges 24, 20, 18, 16, 14, 12 and 10. Charts and more info available here:
dronelab.se/siliconewire.html
The most important chart (maximum current vs wire gauge) is in the thumbnail, so you don't even have to watch the video at all. But you are still invited to do so!

SUPERCAPACITOR powered drone
Просмотров 123 тыс.6 лет назад
Can a SUPERCAPACITOR, marketed as a high-discharge energy source be the ultimate battery for a racing drone? No. No it can not. For the sake of complete information: We charged our 7-cell, 200F supercapacitor pack to maximum allowed voltage seconds before taking off. The VTX and camera were running from a separate, tiny li-po for the purpose of recording the crash when the supercap is empty. A ...

Are the cheap Flysky radios really much more laggy than the Taranis? Spoler alert: It isn't. It's actually faster. Measuring the Stick To Output Signal lag (STOS lag), method is described in the video. Tool used: Saleae Logic 8 Pro @ 50M samples/second. Receivers used: X4RSB for the Taranis, and X6b for the Flysky. High resolution graphs: imgur.com/a/zo17C Decoder plugins: ibus (flysky) github....

    I have a question, I've been using my XT90s connectors on my electric bike for almost six months, just plug and play. Now all of a sudden I'm getting a spark, I can't see the spark but I can hear it. If the owner of this video do not respond can someone help me solve this problem please, I just don't want to purchase a whole new setup and end up with the same results.

    Is there a straight wire connecter that can handle the watts/amps of a xt60? Sort of, if you could cut a xt60 in half, allowing each wire to move independently. Backstory: I bought a board, has to be assembled. Can't connect the battery to the Controller Box as the xt60 is too large to make it through the cable hole connector. They told me that I need to clip off the xt60, run it through, then somehow reattach. Thanks.

    If you say "Everything you need to know" then in the video should be everything. But i don't see comparison XT30 vs XT30U vs XT30WU and etc. As well when soldering wire to the connector, you should connect male+female connectors together, to have a twice bigger area for heat dissipation so the plastic would not melt.

  • @laurentsosson1739
    @laurentsosson1739 3 месяца назад

    HELLO I am contacting you because I would like to know if the XT90 connectors can withstand direct voltage and current 28 volts in approximately 40A? in fact I have a pack to make in lifepo including 4 batteries in // or 8S/4P given that I have 4 batteries in // per series I was thinking of putting 4 cables and 4 XT90 for the pole + general and also 4 cables and, 4 XT90 for the least general which will be put on the B- of the BMS the current that will be drawn by my converter will be 140 A max at 24 volts What do you think? with this situation I think that the current will be divided on the 4 XT90s, i.e. less than 40A per XT90 the cable section will be 10AWG by xt90 Best regards laurent

    • @dronelab1280
      @dronelab1280 3 месяца назад

      An XT90 can handle 40A per each of its two poles continuously at any voltage up to its rating of 500V no problem. It's generally not super safe to use connectors in parallel since if one of them fails, the others have to carry the additional load. But, if you have a lot of overhead, this should be fine. Do you intend to use a total of 8 connectors? 4 for + and 4 for -, each with 2 AWG10 wires? If so, you have a lot of overhead. This should be fine. Just remember to not apply any load (have your converter or anything connected to it OFF) until all 8 connectors are plugged in.

    • @laurentsosson1739
      @laurentsosson1739 3 месяца назад

      hank you for the information yes 4 XT 90 connectors on the packs - 10AWG and the same for the + otherwise perhaps it is more judicious to use copper tubular eye connectors instead of XT 90? cheaper to purchase and less risk of defaults?

      Maybe you got the XT60PB-F? It's the PCB mount version of the XT60, intended to be through hole soldered onto a PCB. I wouldn't use it with a wire, the solder joint won't be as good and secure as it should.

  • @AlexandreSchmidtBR
    @AlexandreSchmidtBR 7 месяцев назад

    Shouldn't we be talking about Watts instead of Amps? Because P = V * i, so it would be nice to know at what Voltage this test was applied.

    • @dronelab1280
      @dronelab1280 7 месяцев назад

      While the connector is in fact limited by the power in can dissipate, and that power is calculated from P = V * I, the "V" in this equation is the voltage dropped across the connector due to its electrical resistance, not the voltage between the two terminals. That voltage can be calculated from the contact resistance, using V = I * R. We measured the XT60 to have about 0.90mΩ of resistance total, so, the connector at 100A is dropping only 0.09V. Plugging this into P = V * I gives 9W of power that dissipated on the connector and heats it, potentially damaging it. All this happens while the connector can be delivering those 100A to its load at 20V or more - so 1000's of W of power. The voltage of the system plays no role in heating the connector. For the same reason voltages as high as 600,000V are used in power distribution networks - to push more power through the same conductors - and smilarily fast charging phones use higher voltages than the old 5V standard of the USB - to push more power thought the same thin USB wire.

    Nice video! Thanks for this "limit" test. Without the faintest intention to being picky, the de-soldering on the video might have been partially contributed also to the awg10 wire heating and not just due to the ohmic losses through the connector. A heavier wire might allow higher current, but would be to much weight for a drone. I am planning to use the XT90 for an electric boat motor, weight is not a big problem so i will use the bulkiest wire on XT90 which i can fit. The XT90 was the best priced solution i could find for about 100A loads, I looked at the Anderson ones (too expensive), the SAE (which was immediately dropped as it can handle maybe up to 10A)

    @Magneticitist 10 месяцев назад

    Connectors and ampacity seem to be a funny topic. Certainly there needs to be some standards set for safety, but the reality seems to be that the connector itself, when properly mated with another, should be able to handle continuous amperage well beyond their rating. I don't really consider it when using a particular RC connector beyond what I have the most of at the time, or what I'm trying to just make a cross compatible kind of setup. I don't see much benefit in switching from an XT60 to like an EC5. The ESC's are probably coming with 12AWG anyway, so why is the concern over a small solid connector rather than wire that is only rated for 20A continuous? May be a different standard, but still a safety rating. I feel like when it comes to actual thermal failure, what's going to happen is the wires will desolder themselves from the connectors.

    Tin the wire, insert it into the connector using a holding fixture, place the lightly tinned soldering iron against the wire and the connector pin, and let the heat of the wire and pin melt the solder into the connection. Don't put solder in the connector pin, reheat it, and insert the wire while holding it with your fingers.

      It depends a lot on your setup, but generally it's best to run hotter but for a shorter time. You do not want to let too much heat reach the nylon case before you're done soldering. Try 350°C, if the case keeps melting, go hotter and faster.
