Can I get one to replace my Tesla Model 3 battery pack?

How about my BMW i3 pack?

Anyone else have an EV pack you’d consider replacing for this superior and cheap battery?

Almost forgot, my solar roof battery. Do you have one?

I don't think anyone has a replacement for Tesla than Tesla. They are very tight on who
can work on there car. I don't believe anyone has access to their software. And if they don't,
it won't recognize any battery then Tesla's. Maybe eventually....

Not sure about the BMW.

Solar battery?????? I don't believe it has a battery. The solar panel powers the fan.

I had the prototype Solar battery. It was great! 2 weeks ago I installed the finish version.
It is even better! Very easy to install, it fit perfectly. And it's even better. Driving in the EV mode is
close to 2 miles. And more power! Jack did a great job!

You can't go wrong with it.

 

Insert any EV except the Toyota Prius, ~210 VDC battery. You' all have mastered the battery controller interface and that is not a trivial problem. I've seen a Chinese replacement for the BMW i3. But you've answered my question . . . are you real and have a clue and the answer is YES.

So let me share some of my requirements. That doesn't mean I expect a product but just sharing what I've learned:

• NCA (also NMC) battery chemistry 'ages out' - there are irreversible chemical changes that lock up and degrade the electrolyte, anode, and cathode over calendar time. We can reduce the rate of this inevitable degradation but not stop it. Even on the shelf at an optimum SOC, they age but over decade time scales.
  • A 3d party EV battery is a 'hard' problem like Operating System programming I used to do.
• Full Self Driving (and AutoPilot) work - to reduce driver load and improve safety. There is a promising, open-source, self driving effort but speed and universal application to most EVs will be slow in coming ... no one is being paid in the open source project. But FSD and its derated AutoPilot work and I would replace my BMW i3 with a used Tesla that comes with FSD in a heartbeat for the right price and at least a year of battery warranty remaining.

I chose to replace my former 2003 Prius traction battery with a rebuild using the improved prismatic cells BEFORE the first pack wore out. You are doing good work in the right area.

So KUDOS for what you've achieved and I wish you the best of luck.

A handful of non-employee developers, for the purpose of attempting to make softwear more bulletproof - yes, they're out their. Supposedly it quite handsomely.

 

You left something out.... "Maybe eventually...."
And I said I didn't know.... I didn't say there weren't any....
