Talked with Michael this morning. He’s stoked on the project. He thinks 408v will be too high for the motor. Wants to setup time to meet and discuss early next week. Franz is there a day that works best for you?
in reply to: JJ’s 58 Single Cab! #70624You’re crushing this build! 💪💪💪 working in those tight spots is not easy
in reply to: Dans ‘65 Tesla #70548If you want the most performance, 32 modules split into two 16 module packs in parallel will get you 408v 1000a. 16 modules would be 408v 500a.

LG Chem
Height: 14.25 Inches
Width: 8.00 Inches
Length: 6.25 Inches12 modules will get you 360v, 32kWh (range), 400A, and weigh 456lbs (2 parallel of 6 modules in series)
LG Chem Super Cell
Length: 16.75 Inches
Width: 5.0 Inches
Height: 4.125 Inches12 modules will get you 306.6v, 19.2kWh (range), 500A, and weigh 240lbs (12 modules in series)
Motor 💪💪💪
The motor that you have chosen needs 275-400 Volts, maximum 1150 Amps (I suspect a minimum of about 200-300A), 400kw!!, and weighs 290 lbs
The combo of more Volts and Amps equals more power. You can add more of the super cells in series to get more voltage and range.
See how many you can fit and let me know what you’d like to do and I will call up EVWest

in reply to: Dans ‘65 Tesla #69705Hey Franz the model S modules are great. You’d need 16 of them to run the tesla motor. Space for that may be a challenge which is why I recommended the one’s above.
in reply to: Dans ‘65 Tesla #69598haha I’d say they are FLUSH with batteries
in reply to: Dans ‘65 Tesla #69522Just spoke with Michael. His recommendations we’re either using these. 6 of them in series would get you to the required voltage and fit nicely in the luggage space of the bug. Could fit 6 more in parallel to increase amperage and range
He also recommended these JH3 LG Chem Super Cells. 12 would be required to get to operating voltage, but he mentioned that he had just received another version of these modules (JHP) that have 2 already in parallel that they’ll be adding to the store soon after they finish their testing. (to me these look like they’d work better for a bus conversion)
He did warn that the large Tesla motor is hard to run in a bug due to the high current and voltage it needs and that it’s too much power.
Here’s a good resource I found on their website. https://www.evwest.com/catalog/product_info.php?products_id=476
All of these batteries he has in stock and could deliver in 10 minutes. – Michael
We talked about the Jehu mustang cells and he said that these are going to be torn apart modules with the wire bonds between the cells cut. Effectively you would be buying the cells and building your own modules/pack.
Another note is that the EVWest modules come rewired with new BMS harnesses so that it’s easier to get things wired up to the BMS.
in reply to: Dans ‘65 Tesla #69521Mach E cells or modules? Looks like the Mustang battery pack produces a little over 400v so that will be enough to power your motor
in reply to: Glenn's Weekend Blue 1963 Ragtop #69460Still dailying the bug. Still running great. Gave the roof rack a quick restoration recently. Currently in almond color but I may change to a gray.
We’ve had this bug for almost 11 years now. Was Will’s first car in high school for the first 3 years. Then my first car and only (drivable) car up until a year ago.
I’ve packed all of my belongings in at several times
And brought along many friends
I’m very grateful for all its years of service to our family.
in reply to: Dans ‘65 Tesla #69459Hey Franz, I can call up Michael Bream tomorrow. He always has his ear to the ground on sourcing batteries so at the least could give some suggestions on places to look.
in reply to: JJ’s 58 Single Cab! #69458Glad to see this finally getting built! Happy it’s in your hands John
in reply to: KCW randomness #68215I say you go full 2000s rice Franz. Roof scoops add at least 15 horsepower
in reply to: KCW randomness #68181Pretty cool app here for any engine builders out there (or to just mess around with)
