Endless Sphere

Where did you get this motor?
I have only seen it on Alibaba.

As I can see from Okashira pictures his cells are 2013. I have like 30 such cells sitting in my basement for over 5 years, they are all still above 3.2 V . removing cells from modules can be a pain with terminals welded but unlike in Nissan Leaf modules, A123 cells are not glued together. Mine were...

I would love for you to be right. Awesome hotroding potential. Based on some more speculative estimates on my part, the Model 3 pack is probably capable of more power then even the P100D pack. Perhaps as much as 650kW in short bursts. Cells are up for it. Bondwires, contactors, connectors, couldn't...

I read a report that indicated they were somewhere between 300 and 333whrs/kg.
If that's true, i wonder what we're all doing with these lower density cells laying around.

The gravimetric energy density is actually slightly worse then the NCR18650GA

is the internal resistance already known? love to see discharge curves with temperatures. i am really interested how cool the cell can stay without active cooling. and more importantly: what are they going to cost if they hit the market... I suspect ~.00045 ohm per group or 0.043 ohm for the whole ...

I thought I'd share what I have learned so far of the Model 3 cells. Made by Panasonic in the USA (duh) 21700 form factor. 21mm diameter and 70mm length. 4.8Ah nominal. 3.65V nominal. Reduced cobalt and increased manganese in the cathode compared to previous generation Silicone in the anode like the...

Yes, regen is possible, in fact, the BMS won't be able to stop it even if the cells go over voltage. That's the issue here. With a single port BMS, the regen would get cut off if the cells went over. With a two port BMS only the charge port turns off for over voltage. About the only way this would ...

Waiting for it. Needs to be waterproof

MX150's are nice. Tesla uses them extensively.
The hand crimper is reasonably priced and there are a massive selection of contacts and housings.

I know a couple of startups... you can contact me

I just ordered one for some testing.
How soon will it ship?

Are you going to be using it long term? How is it working out?

Just found this thread in my search for recycled Tesla cells. It's a great service you are doing for the ebike community. I am really curious to see the differences between the 3.1 Ah and 3.4 Ah cells. I would assume that the IR is higher in the higher capacity cells. Anyway, a pack like this seems...

Email me.
SOld out but about to bid on cars.

How did you get this car. They were supposed to be destroyed./ Recycled.
I want that pack.

200kwh in the roadster gets huge omgwtfbbq from me. Woulda been cool if they went with 140kwh and higher power cells and took off 200lb weight But I guess they wanna use all the same cells model 3 and roadster and model s. 200kwh is just over kill lol Even with the high density cells the pack on the...

Hi methods, I just saw your post - I have an AZD Transit Connect as well. It is not running. Appears to be a problem with the charging process. At the moment I am flying blind. I have a Kvaser CAN interface but I don't have all the AZD software. I downloaded the drivers from the link at EVTV site, ...

Cannot ship small orders overseas

Hi! I would need two packs of made from tesla cells. Pack 1: 20s 8p - 160 cells Pack 2 20 5p - 100 cells What would be total cost shipped to Finland? The packs would need to be crated, shipped via sea freight - and you would need to pick up at your local port. Cost for shipping would be on the orde...

Finally!! Lol

Overseas only for large orders >600 cells

We have a huge improvement in custom pack quality on the way. We've built an industrial quality 3d printer and here is a peek at new cell holders and an early case design.. The material is Nylon 6/6, right off the printer. It will be even tougher after it's aged (absorbed moisture to equilibrium). ...

Well there is also the NCR20700A, lower 3200 mAh but higher C rate. Didn't know this, that's GOLD ! http://lygte-info.dk/review/batteries2012/Sanyo%20NCR20700A%203100mAh%20(Red)%20UK.html At maximum rated current they are up to 81°C 30A at only 81°C , what is the magic trick behind this ? http://ly...

Started a 5L V8 with a 7p4s pack of Tesla cells (no lead acid - disconnected) easily....
