2025 Flash - Battery Size Determination PSA

[HOTAS]

Yeah, I'm not a fan of Ford giving out the FCSP as part of their Power Promise. They make a 48A charger that would have matched better.

The bad thing is folks like you paid a lot more for a 100A circuit instead of the 60A you could use. Of course your next EV could take advantage of it.

The circuit, yes. The FCSP , No.
It’s CCS plug is a disadvantage on many other EV‘s for AC charging.

One advantage would be that the truck could power the house directly with its DC Volts/Amps via the CCS cable?

Not without thousands of dollars of extra equpiment, inverters, wiring and installation.

I wish. I already had 30A tied to the house and would run a generator through that when needed. I can run the Lightning through that circuit. I can run the entire house minus the A/C. Actually, I can run the A/C through that too but I'm not pushing it.

My 100A service is a separate line with a separate meter that was supposed to provide cheaper rates. I won't get the cheaper rate but I did get a $500 credit from Consumers for that line.

On the plus side, I was able to charge up from 7% to 90% using the 48A FCSP relatively quickly. My 30A circuit was good for only 24A so my charge time is cut in half using the FCSP setup.

All good. When I spec out an EV next year, I'll look for the dual charger. I just can't believe I missed that detail.

Was just looking thru the owner's manual, yeah I know I'm a unicorn lol, anway the sticker for my 25 Flash states it has a 123kWh battery but the owners manual says 142.1kWh, so which one is it?

 

[watts/up]

Looks like that refers to the “bigger” 131kwh extended range battery, usable vs max capacity:

As to which you have, I would assume the sticker is what you’d reference.

The Owners Manual is likely not updated. Decode your VIN (see post 1). If the 8th character is "U", it's a 123 kWh.

142.1kWh probably refers to actual battery size. 123kWh is your usable battery. Ford adds a buffer.

That makes sense.

Online manual is the most updated they have. That's where I got that info on it. owner.ford.com

The info came from owner.ford.com using the Vin# of the truck.

Just because it's the online version doesn't mean it's updated for the 2025 Job 2 trucks. That chart looks to a holdover from 2022.

Unfortunately, it still doesn't answer my question.

Ignore the Owners Manual. What is the 8th character of your VIN?
If it's 7, the usable capacity is 131 kWh (nameplate capacity 143.4 kWh).
If it's U, the usable capacity is 123 kWh (nameplate capacity around 134.4 kWh).

It's a U. I suppose this is one of Ford's notorious misprints. The workshop manuals aren't much better.
