Hey guys, was biking through the woods and found this, anyone knows what it is? Cybertruck for scale
In all seriousness, almost unreal to think I'm holding a 4680 in my hands, straight out of Kato Rd.
As some of you know, I've never been into a Tesla, hell, I only ever saw two in my life so far, one Model S 70D years ago in a event, and more recently a stunning white Model Y Performance in a traffic light as I went by
Feels like having a piece of automotive history, or even a piece of history, specially since this is a V1 that isn't produced anymore. The most amazing part is that here in Brazil, the 4680s are the most cost effective cell ($/kWh) to get for DIY projects, the biggest challenge is that the positive terminal is aluminum, which can't be easily soldered by conventional means
As a side note and as a warning, if you plan to use one for your own projects, don't unless you have a really good idea what you are doing, they lack a few of the safety features most if not all other cylindrical cells have such as the PTC switch (positive temperature coefficient) and the CID (current interrupt device). So lets say you are fooling around with it and short it with a tool or even a ring on your finger, you will have a really bad time, quite worse than any other cell
And as a question, any cool ideas what to do with it after I test it? Maybe just a nice stand for it or a transparent USB power bank so it's useful and you can still see it
