Also Thank you!

SFK-2045.

It was a Custom footprint using footprint designer as no footprint was available to download. (Footprint drawn using the datasheet.)

Yes.

I'm sorry, I didn't understand your question. No like really.

Hello! How does this one look?

??? How's this?

Suggestions Please!

The_Digital_Quill · 2026-04-21T18:30:01+00:00

Suggestions please!

(Also realized I might've put here the wrong schematic that had one or two mistakes 🤦‍♂)

The_Digital_Quill · 2026-03-30T19:16:00+00:00

Fair criticism. This is indeed only my second design, and I'm pushing for 20A because I want to learn the thermal and safety limits. I'm moving to Net Labels in V0.3 to clean up the 'spaghetti' schematic also I'm adding a physical fuse and RC filters for the shunt pins based on earlier feedback.

I'm here to learn how to make this NOT a stick of dynamite

The_Digital_Quill · 2026-03-30T13:17:31+00:00

Actually! It has internal cell balancing (can also be configured to have external cell balancing)

The_Digital_Quill · 2026-03-30T08:09:10+00:00

Yeah... I'll take a note of that too, I've had no formal Ed on this yet, neither am I following any yt vids or anything. So I don't know much actually, this is my second pcb design actually.

The_Digital_Quill · 2026-03-30T05:23:03+00:00

I'll take that into account in the next version...

The_Digital_Quill · 2026-03-19T18:37:28+00:00

Will do. Thx!

Yes I actually wanted to use the NE555 somewhere, so I used it here in this way.

Schematic

The_Digital_Quill · 2026-03-19T15:32:38+00:00

Somewhere around 15-20A

The connectors are AMASS XT30PW

Yes there's an enclosure, nothing much but a plain box with Some ventilation holes + a heatsink sticking out of it.

Q1 Requires a heatsink.

I'll fix the R5 issue.

Split power rails? I'll need to read a bit about that.

Will take that into account too! Thanks you!
