@Shadowfax build, i agree very hot

[ShutterShock]

Can only be the shoulder model himself

Lol quite the amalgamation of parts

[Shadowfax]

@rusins

Lacroix board, but with the slim enclosure.
Duck handle. With an airtag holder?
3ds drives on hypertrucks? With newbee rims?
Bioboards branded Davega?

Hehehe. That is my board. I got it as a stock lacroix naz ss with falcon drives and a 100% dead battery.

The boardnamics gear drives are 5.5 ratio straight cuts with 151kv reachers.

The AirTag holder houses the GPS unit for the metr pro can. I discovered that the lacroix carbon weave 100% blocks gps signal.

Bioboards davega by way of @Skyart

First 2023 P42A’s I’ve seen!

[frame]

these are very fresh, March batch i think

[Battery_Mooch]

I think it’s Feb 26th.

[frame]

ah yes, close enough to march, very fresh nonetheless

[bearlyrecognized]

Is this fact or fiction?

[glyphiks]

Definitely fact. Welding in the centre of the cells can compromise the internals of some, if not all cylindrical cells. Best avoided if at all possible.

There is a graphic floating around that has been pulled from the data sheet of a particular cell that explicitly states not to weld there, and so our best practice has just kinda evolved to avoid it on all cells as a safety precaution.

[bearlyrecognized]

Im a smidge skeptical however not at the data or annecdote meerly based on the year. Suprising to me to say the least. What makes the center different from the edge or is the morw conductivity in the center or thinner sheet?

[glyphiks]

It’s because part of the internal structure of the cell connects to the external shell at that point

@bearlyrecognized

makes the center different from the edge

the center is right where the internal weld is that connect to the cell can, its highly advise to avoid the middle 3mm diameter area when welding

@Battery_Mooch can explain better about cell internal structure

[bearlyrecognized]

This is what i needed.makes sense no arguments, just curious.

@glyphiks

Here are three of them, all Sony/Murata. Note that two of them have both the center and a ring further out that are “do not weld here” areas. I don’t know what’s going on where that ring is. Someone (not me) would have to tear down a cell to, hopefully, find out.

[xsynatic]

Also this

@Battery_Mooch

The Lishen SD and SF have bottom vents.
The Lishen SA and LA do not have bottom vents.

@Battery_Mooch

Outer ring?
It was the sort-of-centered vent ring on the bottom of the cell he was welding on. We might still be able to spot weld on the outer ring of normal flat metal on the bottom. But we just don’t really know yet.

But even if we avoid the ring we are still blocking the bottom vent with the nickel strip and that cannot be a good thing.

I imagine there will be ones for Ramm soon enough.

Please use silicone wire… this does not look like a good idea, and with the enclosure being CF, prone to shorting

[marketthrowaway]

Think this is what they call DIWhyyy

[Cyanoacrylate]

Yeah, this kind of thing makes me extremely uncomfortable
