  1. So... About that winch....

    Good find indeed. So if you want a winch, you're adding a 12v battery and charger off the 48v system. Hacky. 48v winch buys you nothing given lack of power capacity available.
  2. So... About that winch....

    There are lugs connected to 48v battery in frunk with plenty of power, though I haven't seen documentation of how much. From there you can buy a 48v winch or pick up a 48v to 14v converter with more than enough capacity for under $400. Given the price and selection of 48v winch, the latter is...
  3. Dear Elon!

    Tesla Semi probably fits your bill there, and it supposedly has the range, too. 😁
  4. New Cybertruck Business Idea: Selling your electricity to people waiting in line at EV charging stations

    Yes, that is entirely what you should have taken away from my post.
  5. New Cybertruck Business Idea: Selling your electricity to people waiting in line at EV charging stations

    You realize that is entirely staged, yes? The money making scheme is the YouTube video.
  6. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    Beat me to it. This, definitely. Battery is probably also the last resort power to get the car stopped while under control in a main battery failure incident.
  7. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    Of course. God I wish the technical data would be released already. I know I can at least afford that much of the truck. 😅
  8. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    I gotcha. Personally, I would probably give mine a quick wrap of electrical tape, but check out all the ground points and how close they are to your car battery positive terminal. Include the metal hood. Not at all disagreeing that you really, really don't want to short it, but it looks a...
  9. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    Random note: Cybertruck is using 20a circuits/outlets. You look up the power allowance on the terminals, design for accessory to be under it, and put a fuse inline. Steer by wire changes nothing. 12v bus is critical to modern vehicle operation for at least a couple decades. Not rocket surgery...
  10. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    Also, I get the intuition that leaving the 48v bolt uncapped feels very wrong, but that is a reasonable low voltage install. Modern cars have plenty more DC lug exposure than that.
  11. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    You can't jump a cybertruck with 48v. If your 48v bus is dead flat, your 800v bus is flat. Or worse problems are going on. If you ever have to jump 48v bus to get enough smarts working to communicate NACS charging, you probably should not be charging the destroyed battery pack in first place...
  12. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    There is the 400w switched tap. There is also shown two bolts next to the 48v battery which directly tap said battery. I mean, nobody said anything about that being where winch accessory gets its power, but that is 100% where wrench accessory gets its power.
  13. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    I will mention that I did watch the whole video and saw they have tap to 48v battery. I'm assuming that will be plenty capacity for winch, though a constant load like a snowplow is likely to be a problem depending on what the spare capacity of the dc dc converter they are using is.
  14. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    That control bus will already be protected and isolated in any vaguely reasonable design let alone safe. With an already hefty 48v bus, bumping it up a bit more to provide an unswitched and protected high power power tap shouldn't be significant relative expense and extreme oversight to not...
  15. Frunk Auxiliary Power Tap / Power Feed Specs (48V and 400W)

    I'm guessing these are just the 2 switched accessory taps. I very much expect an unswitched DC tap of significant rated capacity and most likely 48v.
  16. Cybertruck L2 Charging -> Tesla Gen 4 80amp Wall Connector

    This thread is on fire. Literally. Electrical house fires specifically.
  17. How best to wire in 12VDC accessories, Like Ham Radio.

    Winch option exists, which means the power to draw from is there. 48v to 13.8v or 12v are readily available with 2kw or more capacity. A couple of 12v car audio system capacitors could even help shore up reliability and lessen stress on the converter. Native 48v winch would be 'ideal', but the...
