Of course not. Test platforms are not designed to go commercial.
Here is a ready to go commercial model being field tested.

I would like to see this electric air taxi succeed:

Looks like the same plane in both articles.

Everybody just goes ga-ga over anything "electric" even if it makes zero economic or systems sense. This is all to appease the Global Warming Gods and their fictitious "crisis."
Take a look at the energy storage capacity of various types below. You'll find batteries near the bottom. No battery is ever going to compete with a hydrocarbon fuel. I don't know why we just don't jump straight to antimatter!
| Storage type | Specific energy (MJ/kg) |
|---|---|
| Antimatter | 89,875,517,874 |
| Deuterium | 579,000,000 |
| Plutonium-239 | 83,610,000 |
| Uranium | 0,620,000 |
| Hydrogen, liquid (LHV) | 120 |
| Hydrogen, at 690 bar and 25°C (LHV) | 120 |
| Hydrogen, gas, 1 atm, 25°C (LHV) | 120 |
| Methane (1.013 bar, 15 °C) | 56 |
| LNG (−160 °C) | 54 |
| CNG (250 bar/~3,600 psi) | 54 |
| Natural gas | 54 |
| Gasoline | 46 |
| Diesel fuel | 46 |
| 100LL Avgas | 44 |
| Jet fuel | 43 |
| Body fat | 38 |
| Coal, anthracite | 30 |
| Ethanol | 30 |
| Coal, bituminous | 25 |
| Methanol | 20 |
| Wood | 18 |
| Peat briquette | 18 |
| Coal, lignite | 15 |
| Sodium | 13 |
| Gunpowder | 10 |
| TNT | 4.2 |
| ANFO | 3.7 |
| Lithium metal battery | 1.8 |
| Battery, zinc-air | 1.6 |
| Lithium-ion battery | 0.9 |
| Sodium sulfur battery | 0.9 |
| Alkaline battery | 0.5 |
| Nickel-metal hydride battery | 0.4 |
| Lead-acid battery | 0.2 |
| Supercapacitor (EDLC) | 0.03 |
“And unlike the jet fuel which is burned off, the whole weight of the batteries is there from start to finish.
So ends my extremely limited knowledge of the subject.”
Actually that’s a huge deal, as all of the larger airplanes have a takeoff weight FAR HIGHER than their landing weight, which is why they dump fuel if they need to land early. Imagine them dumping Lithium Ions!
Yep, makes no sense, but it sure makes people feel good....
“And unlike the jet fuel which is burned off, the whole weight of the batteries is there from start to finish.

Jet fuel burned off at a rate of $200 per hour versus $15 for electric.
Also compare maintenance costs! Not to mention extra training and operating overhead required of. the pilot.
“No battery is ever going to compete with a hydrocarbon fuel.”
Tesla is doing quite nicely.
Watch Corvette get embarrassed by low-end Model 3.

“quite nicely” has nothing to do with the physics and chemistry of energy storage.
“Not every flight is 1000 nm!”
No flight is 1000 nm if you’re in an electric plane.
“Actually that’s a huge deal, as all of the larger airplanes have a takeoff weight FAR HIGHER than their landing weight, which is why they dump fuel if they need to land early. Imagine them dumping Lithium Ions!”
LOL! Please show where the dump fuel switch is on the Caravan!
For how long or far???
“No flight is 1000 nm if you’re in an electric plane.”
Longest flight is over. 5000 miles. China. to Hawaii.
You didn’t watch the video.
“Jet fuel 43
Body fat 38”
Hmm, I think I’ve got my million dollar idea. I’ll start an airline that offers in-flight liposuction and use the fat we suck out to fuel the plane!
5000 miles in an electric plane, without recharging?
What are you smoking?
Notice he said “all of the larger airplanes”?
I don’t think a Cessna is a “larger airplane”.
“Of course not. Test platforms are not designed to go commercial. “
My comment about lead acids holds. We did have electric cars in the lead acid days, but they were far from practical. It wasn’t until lithium ions (and then with billions of federal dollars) did they get any widespread traction.
So, yea, if batteries are able to take another leap in energy density, then obviously they might work for airplanes - but this stuff just shows that electric motors can power airplanes. Not exactly cutting-edge stuff.
“LOL! Please show where the dump fuel switch is on the Caravan!”
What part of “Large Airplanes” is giving you trouble.
If you’re aiming at 1% or less of the aircraft market (Caravans and smaller), and if you guys even manage to get that far, you guys will NEVER ‘save the planet’.
It’s hopeless. Wait for much,much, better batteries.
