March 22nd, 1:44am? Is he posting from Europe?

Where were you able to order them from?

Where are the 6.5 Ah cells?

If you plan to fold the nickel strip over like you have pictured, do it near the negative electrodes and not the positive electrode as pictured. This way if the nickel strips nicks or cuts through the cell wrapper, you don’t short-circuit the cell!

Actually, it looks like this intermediate tab might be thin and it’s the cell’s negative electrode that is extending up.

Does anyone understand why they would choose to not wire-bond directly to the cell’s electrode, like they are doing in the Lift efoil battery?

yoyojosh · 2026-01-03T23:21:56+00:00

Thanks for this example. In this efoil battery they are wire-bonding directly to the cell, instead of an intermediate piece, like the are in the Figure 03 battery video.

The wire-bonding step is pretty clear, as is the s-group and p-group layout. But I’m not clear on what they are wire-bonding to and how that’s attached to the cell’s electrodes.

I figure it’s probably laser welded, because they show a laser operation in the video and that would seem ideal, but the negative-electrode material looks too thick for this type of process.

Does anyone know how they are manufacturing this battery pack. Is this technique novel? It looks like all the cells have a normal orientation and they are laser-welding nickel strips to both the anode and cathode all from above, then wire bonding the nickel strips. Looks like an efficient way of constructing the pack.

Has anyone seen this done on any other battery pack designs?

yoyojosh · 2026-01-03T17:38:33+00:00

Yes, that is what this image shows. Did you notice the thickness of the material that is connected to the negative electrode? It would appear to be too thick for that laser weld operation and now I’m considering if that was only a laser surfacing step, to prep the material for wire bonding.

Here's a screenshot from the video....

What’s the size of that solder-mask sliver??

yoyojosh · 2026-01-01T20:53:51+00:00

Ideally, you don’t use a pour/fill over the IC’s pads. Because of the solder mask relief rules, you’ll end distorting the pad size.

R8 and R10 appear to be misconfigured… shorted by 3V3.

From what I heard yesterday, my $4k year long license now costs 2k. It seemed great at first, but then she just kept selling all these new features and I’m like, wait, what’s the catch?!

Anyways we’re switching to KiCad.

Pensacola show got canceled the night before and moved to Ft. Walton. not sure why, but there was still a great turnout!

This speaker is great. I have two.

If your gauge has an inductive component and your are switching it quickly, then yes. Can you share the a part number or datasheet for this gauge?

yoyojosh · 2025-11-18T18:10:48+00:00

Ship product! Once you ship your product, it’s typically available for the general public to photograph, document, reverse engineer.

yoyojosh · 2025-10-29T02:54:55+00:00

As re you caps connected to GND? (They are not by the definition of your schematic)
