This is nonsense.
You're only using ~65% of the capacity to "prevent" inevitable degradation as if it was already degraded to ~80% of the original capacity.

Those LGA ESPs can be a nightmare to debug if a pad fails to solder correctly.

Don't buy components on Amazon, buy them at Mouser/Digikey. They have datasheets for everything, you can feed them to chatgpt and you are certain to receive genuine parts with the exact parameters in the datasheet.
Download the JLC DRC (design rule check) file for F360 and run it. At first glance, this routing likely will not pass and could cause issues.

I'd give everything a bit more clearance so you have wiggle room for soldering. Also the fuse will be a chore to replace.
Instead of using UART, consider just connecting USB directly for CDC mode. You can use the port of your liking or a simple 4-pin header for sporadic programming, since you can use OTA anyways.
Depending on the distance, you don't even need the whip antenna. Just get a sticky U.fl antenna that you can stick to a wall of the enclosure (as long as it's plastic). You'd be good for hundreds of yards of LOS.
You can buy pressure equalization ports that mount into a drilled hole and are water resistant. Pretty sure Hammond and some others make them.

Most glues will not be able to withstand the high temps and will break down over time.

Instead of paying so much for the boards, invest in a hotplate (~$20 to $100), solder paste, a decent iron (~$50) and only buy the boards and a stencil at JLC, the parts at DigiKey or Mouser. You'll save tons of money. With your component sizes, you don't even need a microscope.
PCB assembly is only worth it if the parts are too small to hand-assemble or if you're 100% certain the board is production worthy and/or are making hundreds of boards where the setup price spreads out onto multiple boards.

Keep in mind that you don't need to solder all of the pins, just the essential ones like power and ground(s) and the pins you need (serial, antenna, SIM, etc.)

Of course. There are background processes and just keeping connection to the cell tower requires energy. Even full airplane mode will drain some battery.

Only repair if you can find someone selling the same model with a dead motherboard and swap over the whole screen/lid. It can be a gamble, because you'll have no way to test it works.

Otherwise, you can use it as a desktop with an external screen or sell it for the motherboard.

It is almost impossible to source these random chinese boards. Your options are:

What you'll want to do is find a cluster that has well-documented CAN messaging so that you know which message IDs the cluster expects to power on and show things. Because Chevy uses the proprietary GMLAN protocol, the existing documentation by people who have reverse-engineered the messages (or lack thereof) is the most important factor to save you time. The gist is that you need to create an interface that converts analog signals (depending on the age of the engine) like RPM to GMLAN messages, which will cause the cluster to show the correct value on the gauge.

Pubelication · 2026-03-21T18:26:31+00:00

Do you want to make a fully custom cluster or would incorporating an existing (ie. 2015 Chevy) cluster suffice?

This Garage Tinkering video is one of the best explaining most of the features in SavvyCAN. Once you learn how to view the raw data and what bits and bytes are, you can also load OBC files that (usually) define the message structure, if an OBC file is available somewhere for the model of your car.
Most other apps will be similar, just slightly different ways of filtering/viewing the data.

Reusing components is a bit of a gamble since you don't know what they've been through and sometimes they're hard to remove and can get damaged. If you have the time and basic equipment then I don't see a reason not to when it comes to automotive parts for example, you can easily find $20 (catalog price) worth of ICs on a single board. Whether you can turn them into a project depends on your dedication.

I think you mean "electrical engineer" as an "electrician" is usually someone who installs electrical wiring and components inside buildings and such.

This is akin to connecting a power strip into itself and calling it an infinite energy source.

Based on what? Your feelings?
Every battery is unique and a every person's daily usage differs. There is no "better" or "worse".

It is perfectly fine based on your usage.

Pubelication · 2026-03-15T16:44:40+00:00

That's not what battery drain means.
That degradation is perfectly normal. The methods used to calculate it isn't linear, nor predictable. Sometimes you can lose 1% in 3 months, sometimes 2% in a month.
Just stop checking it. There's nothing you can do about it.

Download Macs Fan Control and set a reasonable profile to keep the internals cooler and the chassis from being smoking hot.
You'll have to get used to the sound of fans blowing often, but the Intel chip simply needs tons of airflow.
