Tesla owners, squeezing in a 21700 battery pack, possible?

Recommended Posts

I don't have a tesla but I consider getting a V2 or newer.

I'm curious to maybe upgrade the batteries using 21700 cells instead of 18650. The difference is 3mm larger in diameter and 5mm longer.

It would mean that the twice stacked cells would enlarge the pack with about 6mm thickness, 10mm taller and 30mm wider.

Is it possible to make room for it?

I don't have Tesla either but this is picture from EcoDrift website. It seems that the bracket where the battery sit leave no more room in any dimension. I don't think it will retrofit-able unless Gotway change the inner shell or reduce the number of cell and add extra padding like those 100v version of Nikola and MSX.

Thanks for the pic. It helps. Tesla owners, any comments?

It would make the tesla 1500Wh instead of 1020Wh. Interesting?

Also could someone comment about the issue of water intrusion into the tesla v1 and v2? Is it common? Is one better than the other?

I ride my tesla v1 in rain all the time since I bought it a couple of years ago when it first came out, no problems at all.

And here it is. An original tesla v2 with 1480Wh from the factory. ~20kg

Nice! There's a lighter wheel with range again!

What's the source of the information?

Just an ad in the chinese 2nd hand pages. I was browsing and caught the 1480Wh.

Is the bms external on all teslas?

Does it have two bms's or one?

Two... one for each pack.

21700 batteries do help sometimes to pack in more capacity but they are not higher density. The wheel does become bigger and heavier by a similar proportion as when using only 18650 cells to reach the same capacity.
