With bigger meats, you'll need tractor weights on the front 😂

Don't understand how (or why) the Tesla LDU will play nicely here.

So, I was curious to see what's needed, beyond rear lawn mower engine logically replaced with Tesla LDU, and confirmed my suspicions on what's needed to keep from shredding the sheet metal with the power levels:

 

[remy_martian]

He has relied on tires/axles as fuses and seems sensible about easing power in. He's basically steering the LDU, lol. He hinted that he's tied his subframe into the roof arch, using tubes and sheet metal doublers, and braced the frame horns.

The situation becomes very different when you put big meats on with a drag compound tire and you floor it.

Lifting the front wheels off on a stock bug (especially with the cantilever a small block Chevy creates, for instance) is very different than lifting all that front battery off with instantaneous full torque from a DU that I'm guessing weighs about the same as the original engine/transaxle. It's like hitting the chassis with a huge sledgehammer.

This will be an interesting conversion 🍿

Eyeballing, that's 4 Tesla modules under the floor...what about the other 12?

 

[remy_martian]

Shoebox modules just tossed his 600HP out the window.

 

[remy_martian]

Which makes my point that a performance LDU a waste of money and weight...the M3 performance seems like a better choice all around, including physical track width.

NiCd or Pb-acid

(next thing, he'll be concerned about weight... 😂)

Wow the negativity is strong in this group. I said from the beginning I’m building a toy not an electric 1000 mile range yugo with a top speed of 35 to carry the kids to kindergarten. I’m done with that phase. Thought y’all would appreciate something different. I definitely walk to different beat. guess I’m on my own here.

What "group" negativity?

You got an assessment of a stationary tech being inappropriate for vehicle use. You could just buy them and spend the money, since the answer came from a prolifically posting "troll" that should be limited in the number of replies 😂

You also got an answer to your question on high current from me. Along with the cost. You didn't state that weight was a constraint, so you were warned about it.

Lithium is not a high current technology. You asked for high current out of the blue. If you plan to do:

"for sale. VW Beetle. Low miles. Driven by little old lady 1/4 mile at a time", then say so. It's a totally different solution set on the engineering side.

Engineering is not a place for snowflakes. Either man up and take the unbiased information as candidly given, which is what engineers are trained to do, or ignore it and do what you prefer because someone sprinkled sugar on it cuz they have some to ditch on eBay.

If you want high current, lithium's not the best choice, imo. There's no magic lithium chemistry that will give it to you, like you thought you found. Mother Nature doesn't make free sandwiches. Someone pointed that out to you.

My upbringing says to thank the person for their time, research, and OPINION vs whining about its delivery. It also gives everyone a voice and doesn't mob-muzzle valuable contributors just because you don't like their posts, content, or contrarian perspective...in good engineering, contrarian perspective is invited, not shunned.
