2026 F-150 Lightning STX Model Introduced. Replaces the XLT

[bmwhitetx]

Will the 2026 Stx Lightening use ccs or Nacs charge port?

Probably no NACS for 2026 either. When Ford announced their deal with Tesla back in 2023, they said:

In 2025, Ford will offer next-generation electric vehicles with the North American Charging Standard (NACS) connector built-in….

Those next-gen vehicles continue to be delayed. And so far they haven’t changed any first-gen EV to NACS. Would require lots of hardware and software changes to an established and aging platform.

Lightning.

Ford has not announced any change in charging port to my knowledge.

Actually, this loophole wasn't added recently, it's existed for years. The key is a binding contract, with a decent deposit.

It wasn’t the case when I got my truck 9 days past 12/31/23 and missed out on the credit. The IRS regulations clearly stated “placed in service.”

Agree.

When the rules changed in August 2022, they used this language for the period 1/1/2022 to 8/15/22. I don't know when this rule (binding contract) comes into play and when it doesn't, but it's the same requirement. Maybe @TaxmanHog knows.

Lightning.

Official Ford account (Brian, not AI) replied to someone on the MachE forum and said future Ford EV's will be "NACS capable".

Given the circumstances of the post and the discussion, it appears that native NACS port integration is in the works.

Future models, not the Mach-E or Lightning.

Am I correct in my assumption that the STX uses a LFP battery chemistry...

Will not be LFP. Will be Li-Ion (NMC).
The announcement states that the batteries for the STX will be made at BlueOval SK, Kentucky. According to their webpage:
BlueOval SK will make lithium ion batteries to power future Ford and Lincoln brand electric vehicles.
They began commercial operation Aug 19, 2025.

LFP batteries are scheduled to be made next year at the BlueOval Battery Park Michigan and are targeted for the new entry-level affordable vehicles.

8936-A shows the "In Service" date, I don't know if there will be language in the 2025 version for filing in 2026 that accepts a "Binding Contractual Sale Date" in lieu of "In Service Date" ..... we will have to see. This situation would mostly affect those filing for the credit at the time they file thier income tax return in the spring of 2026.

I also wonder if dealers will try or be encouraged to pre-book sales in the system to get the credit before 10/1/2025, some F&I managers might try such a scheme, not sure how that would go if they were audited!!

@Garyl @bmwhitetx thanks for the clarification. My mistake. I didn't realize the different SK factories produced different batteries.

Am I correct in my assumption that the STX uses a LFP battery chemistry that actual likes being charged to 100% of capacity on a regular basis. If that's the case it actually would have 75 mile + of additional range over my SR Pro at 80% charge.

Great observation re: benefits of batteries that allow routine 100% charging. They effectively give you more routine capacity even though energy density may not be as high as Nmc

While I don't own a full ev yet, currently driving an F150 Hybrid Powerboost, I did install 12kw solar on my home and bought 40kwh of lfp batteries for home backup this year.

According to Will Prowse on his YouTube channel, LFP batteries can be charged to 100% basically daily, or at least weekly.
While Will does not have a formal engineering background, he has years of practical diy solar and battery expertise, reviewing and tearing down and building diy lfp battery packs for his homes

There's been reports from users that regularly charge to 100% on these trucks for hundreds of thousands of miles with no ill effects. Since Ford precalculated usable battery size and SOC, there's less on the table for what's known in the industry as "CYA"

Example using my own truck specs, it's listed as having a 123kWh battery yet the sticker clearly shows it to be quite a bit higher at 134.5kWh. My bet is they balanced this out beforehand to as mentioned, CYA, so that when we charge to 100%, we're actually only charging it to 90-95% (cya buffer).

It's easier to understand in terms of hp for an ice vehicle, every gear head knows Ford leaves a lot of power off the table to (CYA) their engines from rapid unscheduled disassembly. Introduce custom tuning.

I don't know of any way to get more power from these ev platforms however, charging to 100% daily should not be an issue.

Agreed.
The 80% charge rule is about charge speed, not battery damage, degradation.
Charge speed drops significantly after 80%. While that doesn't matter for home, work, overnight charging, it matters for road trip time.
Travelers want to keep charge times low to minimize long distance trips, so usually want to stop charging at 80% when charge rate goes down, which can be very slow depending on vehicle

Agreed most people are blending the different charge profiles for no reason, at home overnight charging, fill-er up.

My driving is 99.9% suburbs so I plug it in infrequently but let it go full.

A small correction. Your 2025 Flash has usable capacity of 123 kWh and nameplate capacity of about 134.4 (not 142.1). The Owners manual reference is to the original 131 kWh battery. Notice it also states 480 cells. That is the 131 kWh ER battery. Your battery has only 450 cells. Thus your nameplate is around 134.4. I explained it here. And a few posts down, a user shows how you can see your battery nameplate.

You still have roughly the same percentage buffer (~9%) as the ER and SR packs so those points are valid. FYI, no one has posted the nameplate of the 123 kWh battery so it would be cool if you could. We have nameplate pics of the other two battery capacities.

Kewl beans, I guess Ford hasn't made the revision to the online manual yet (Fordposs), updated other post to show this factoid. Grabbed my creeper and snagged a pic.
