So... About that winch....

[Jhodgesatmb]

I asked them. Private email. This was made specifically for CT. All their lights and such are either going to have built in converters or run at a native 48v because the only vehicle this line was designed for was the CT/CB. If you want more specifics you can email them and ask but they aren’t giving out too many details yet.

Why would anyone order this winch without specifics. Are they going to run a dedicated wire to the battery? That sounds scary. Are they going to have a dedicated battery? That sounds kind of lame. Lots of people here are interested in a winch and though I appreciate your post I think that ‘they’ should provide more detail about the winch, its mounting, its power requirements and how they will achieve them, and its specs.

Dedicated wire to the battery is normal. But I don't think it matters what kind of lugs are on that 48V pack, I sincerely doubt it can push 5.6kW

I agree. Without a 12v battery bank being charged via converter there is no optimal solution for a winch right now. The perk of 12v systems was the ability to up your battery size for reserve power. A prius for instance sees performance gains from larger 12v batteries due to them being able to run accessories longer with the ICE off. The 48v limits the ability to expand the power reserves.

"Unlike all the other Tesla passenger EVs, the Cybertruck has a 48V low-voltage system instead of a traditional 12V one, and the battery is rated at just 4 Ah."

4Ah means it's one set of ~12-13 cells in series for 48V. Even if we assume they are the absolute highest discharge rate of 30A 45A (which are the most extreme, unprotected cells), that's not close to the needed 117A.

Good find btw


Edited to correct the max discharge for the most extreme, unprotected 2170 cells. Numbers from 18650s were used initially.

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.

This is what I plan to do to install a hitch or a regular 12v lightbar to my Cybertruck. A step down from 48 to 12. Unless someone points out if this Amazon one is a bad idea, I will probably buy it soon. https://amzn.to/3QX1WcL

I mean, the frunk is plenty large enough to house a 12v sub system like this. I might do this also

That thing is tiny. Like 3" x 3" x 1.5". I would probably just wire it under the plastic frunk tub right by the mods wires.

This thread is blowing my mind, thank you all for the enlightening comments. I’ve always thought the higher the voltage (ie 48V), the lower the current required. In the end, power, which is voltage X current would be similar for 12V and 48V systems. But guess not. Perhaps thinking outside the box and going with a 120/240V plug in winch that’s welded to mount to the hitch would be the best idea? Removable, until needed. Does this have an integrated AC-DC converter?

I meant your battery. A winch will pull a lot of current at load, you need a good marine or car battery.

That's a 12v DC winch. Most ac winches that I know are overhead hoist style things. But that is certainly outside of the box!

You are correct, this is a crane drum winch….title shows 115V/230V max. Crazy amps though.
