Battery SOH - bragging rights or bullshit?

[RickLightning]

I've noticed between the Mach-E and Lightning forums a consistent fact - Lightning SOHs are considerably higher, or perfect, as compared to Mach-E SOHs. Is this because of:

1) Better battery technology on Lightnings as compared to Mach-Es?
2) Better BMS on Lightnings as compared to Mach-Es?
3) Different algorithm calculating SOH?

Thoughts?

Isn't the mach e battery LFP as opposed to our NCM?

Not LFP on all years and models. Our 2025 GT has the 91kWh NCM battery.

I personally don't trust the SOH number. All I care about is my max useable energy when at 100% SOC (displayed).

I'll go with #4. SOH is a hot garbage metric. Those who trust it are probably the ones that complain that their GOM lies.

Nope. Both are NCM. SR starting mid 2023 is LFP.

I go with option 1 but modified:

1) Better Different battery technology on Lightnings as compared to Mach-Es?

After experiencing two failed modules, not sure the Lightning tech is better, just different. Son who lives with us has a Mach-E. Worse SOH, fewer miles, but lives outdoors while my Lightning is garaged.

Nope. Both are NCM. SR starting mid 2023 is LFP.

It was my understanding that starting in 2025 even the extended range (88kWh) on the non-GT/Rally models are LPF.

No

No

Why do they have both an 88 and a 91 kWh battery if they are essentially the same then?

"They reduced the size of four cell modules, making the new 88 kWh pack 4P90S. The GTs will continue to have the existing 91 kWh 4P94S pack."

…that their GOM lies.

Every time I see “GOM“ I think you youngins are a lost cause. Here’s what a ‘62 VW Beetle gave you for a GOM to roll down the highway on. I drove 56 miles on “R” and gassed up to 10 gallons the next morning. It took real math & experience to use the gauge.
