Bigger may not be better when it comes to the battery.

^^^ this is 100% correct for aviation.

The only benefit to running out of fuel in the air is that if you crash, no fires to worry about....

Fuel starvation while in the air is a disaster for any pilot.

Even the Cessnas I fly have the longest glide per altitude still does not make me feel any better.

My CFI said soon he will cut the engine (idle) for power off landings to start my emergency procedures training.

Take a look at N2673J
I did that restoration

Nice job on a 150 !
I hope to own mine soon.

Trainer planes are good to learn on, but I am going to look for fuel injected engine planes - really don't like the piston engine climb performance.

After a little research and some basic math, you should only charge an MNC battery to 80% (120 miles). On average MNC batteries loose up to 30% of their capacity after 10 years (84 mile range) and, loose about 40% below 32 degrees (50.4 miles)

Worst case scenario for the bigger battery is 80.64 miles.

Slate has talked about how great this vehicle will be for the 2nd and even the 3rd owners of this vehicle because they can customize it and make it their own but they never mentioned that the 2nd or possibly 3rd owners will have to drop between $15-20k for a "Small" replacement battery (at today's cost).

Hate to say it but if any of the top 3 auto manufacturers finally wake up and build a small regular cab ICE truck then it's good by Slate.

This truck is looking more and more "Disposable" after about 10 years...

What? No Velis Elctro?

My understanding is that the Slate comes with a 52.7-kWh battery which can be upgraded to an 84.3-kWh battery. That adds an additional 302 pounds to the little truck.

Range increases from 150 to 240 miles. So there is that.

The electric motor rated for 201 horsepower and 195 pound-feet of torque, however, remains the same.

In my opinion, the heavier battery will make the handling feel sluggish, decrease acceleration and reduce the towing capacity and payload.

Because 98% of my time behind the wheel will be local, I think I will pocket the difference and on the rare occasion I choose it to take a long trip, use the money to buy snacks at Buc-ees while I charge up.

Depending on where the Battery is located that extra 300 lbs could be great for traction (hopefully the rear)

also depending on how much you drive that extra battery could mean that you only charge 1-2 times a week compared to 3-4 times a week or more

so if the life cycle is 2000 cycles the extended battery could mean that your batteries last
6x a week = 330 Weeks or 6.3 years
4x a week = 500 Weeks or 9 years
3x a week = 670 Weeks or 13.4 years
2x a week = 1000 Weeks or 19 years (seems like a stretch for a battery to last 19 years)

unfortunately the government would need to wake up and make regulations more conducive for small ICE vehicles, this is the main reason the manufacturers went to the larger wheel bases which made sense for the 4 door vehicles

also $15,000-$20,000 for a battery, this seems like a high guess, thats 1/2 to 2/3rds the price of the vehicle

@ 4:45 minutes it is explained

If it were an LFP battery then 2x a week would make it last close to 60 years. Let that sink in.

And people don't understand why EV's in the US are not as popular as other countries. I'm starting to remember all the reasons I swore I would never drive an EV. A "Made in the US" EV anyway.

That body off frame restoration of an 85 Toyota Truck is looking better and better

"The Government would need to wake up"? Yeah, that's not happening. They were more worried about "Woke Up". Glad that's coming to and end (for now)

Same reason other countries still have small Diesel trucks. Not in the good old US of A.

I'm a lot of ways we really are a backwards country

I think the Slate average lifespan might be a little shorter than that. Like you, I’m scratching my head over the battery type selection…Slate has stated that their batteries will be U.S. sourced and perhaps that goal is playing a role in the decision. A lot can happen between now and production start…

Slates battery decision will be what kills this truck. When it debuted everyone only saw a small 2 door, low priced truck that could be customized and was something we never seen before. The day it was released and we all watched that 30 minute video NOTHING was mentioned about the battery technology that they were going to use. It was only a matter of time for those of us that knew little about EV's and EV batteries to find out the major flaw in their design and this was actually just a cheap disposable truck.

The Glitter Dust is quickly wearing off

All new cars produced today (regardless of price) are disposable. Certainly all Teslas are built that way...they start falling apart in five years...less time if its a Cybertruck. Cars not lasting forever is what keeps the auto makers in business. Even Toyota, the paragon of dependability and long-lasting vehicles, has jumped on the bandwagon. If the battery in a Slate is the only thing that fails in 8-10 years (and I doubt it will be), merely replacing the battery after the vehicle is fully amortized seems like a win to me if the rest of the truck is fully operational...most importantly the motor. There are so few systems to fail that it seems likely that the Slate (other than its battery), might outlast other new cars being produced today. We know the body panels and exterior finish (wrap) are replaceable. Just think about how many ECUs are in a typical new car. How many do you think the Slate will have? Other than those specifically tasked with meeting federally mandated safety standards, I'm guessing very few.

hopefully they will design it to be modernized as time goes on so the next replacement battery can be a newer technology

this is a huge reason Milwaukee Tools has been superior, they designed their platform to be forward thinking
