    Well done video. I like the fact that you make these without any special materials. The only improvement would be to use metal strips instead of wires to interconnect the cells. You can solder them as well, so no need for a spot welder.

    Great video, don't worry about the remarks from those key board warriors, that never have anything good to say and in their wildest dreams have any idea of how much time and effort that goes into making a video like this. As I'm kind of new to FPV and just finished my third build a 7 inch CL2 XR from roto riot ( Ihave skyliner like you as well which ive bashed alot lol) and Im making some 6 s with molicel P42A , being 6 cell will that make them a 6000 mah battery? Or still a 4000mah like these 4 cell packs. Sorry it may sound like a dub question. :)

    • @andrewmedia3568
      @andrewmedia3568  5 месяцев назад

      Thank you! The molicel p42A is Technically 4200mAh for one cell. So making a 6S pack would still be 4200mAh and 45 amp continuous discharge rating, If your just running one single 6s pack. I run 2 6s packs together in parallel so the voltage stays the same at 6s but the amperage increases to 8400mAh (4200mAh x 2) and 90 Amps continuous discharge since im pulling from 2 packs equally at the same time. Batterys wired in series increases voltage but amperage stays the same. And wiring batterys in parallel increases amperage but voltage stays the same. Hope this makes sense and helps. lmk if you have other questions, maybe I can help.

      It’s a bit more than a couple dollars depending what battery your buying. And if you have the money and don’t want to mess with it then definitely just buy a battery and you’re good to go. And saves you the time of building your own. But if you enjoy this type of stuff, building your own gear. this video was supposed to help people that wanted to build their own packs.

    • @andrewmedia3568
      @andrewmedia3568  5 месяцев назад

      Not sure I understand your question. You just need a battery that has at least a 35 amp continuous discharge rating. Doesn’t matter if it’s an 18650 or 21700 size cell. And 4 cells for 4s obviously. The discharge rating is most important. Most high mah have lower continuous discharge and lower mah have higher discharge. But a few cells have both. Like the molicel p42a, p42b and the Samsung 40T I used in this video. Also sony has some good 18650 cells. The vtc 5 or 6.

      @@ziedtimoumi9496 without knowing what the continuous discharge rating is idk. If it’s only like 10 or 15 amps you could kill the cells with one flight or have a quad on fire. I would say they are not safe to use unless you know the rated continuous discharge amperage is.

  • @Cephas2904
    @Cephas2904 Месяц назад

    Great video mate, respect from India. Two questions, how would I know the C rating? And two, will it suffice, since FPVs would need a higher discharge rate as given by LiPo batteries

    • @andrewmedia3568
      @andrewmedia3568  Месяц назад

      Thank you! So I bought these battery's from a Reputable Vendor online. 18650batterystore.com, they specialize in cells used for electric skateboards and bikes and so on. For the name brand cells like samsung, molicel and sony they have the spec sheet and graphs posted on the page for the cell. So that shows the max discharge rating, charge rating, mAh at different temps. So you just need to find some cells like the sony VTC6 or Molicel P42a, those have known discharge ratings like 45 amp continuous. As for fpv discharge rating I run 2 6S packs together in parallel giving me 90 amps continuous discharge (45 amp x2= 90). Thats plenty of amperage for flying long range. I'm typically pulling around 30-40 amps during normal flight at 30-50mph. so that leaves plenty of extra amps for altitude increase or limited punch outs. I just watch how many amps im pulling while flying. You also need to make sure your amp settings are correctly calibrated in betaflight. hope this helps.
