Upgrading to a larger capacity battery, is it possible?

    Ive been thinking about this all day, rather than buying out my P90D at the end of the lease, I should return it and purchase a P85+

    Then an idea crossed my mind, would tesla allow me to upgrade my battery to a 100kwh battery that I will buy from a wrecked 100D, so not an official upgrade through tesla but rather me changing out the battery for a higher capacity one

    Anyone here know if that’s technically possible?

    Sure it can be done. Not by Tesla. Not very cost effective.

    It’s either that or the boring route of just getting a 100D

    I’d love a P85+ with 300+ miles of range

    Boring is probably best.

    If you lived in NC it might be an interesting venture.

    Your buyout + 25K (cost of 100kw pack installed)
    Would be better spent on another car.

    I am not positive but It will most definitely not have ludicrous mode and a quick vin check will reveal that it is in fact still a 90. Really curious on how that would play out for resale value.

    I just read my post and it’s a bit confusing. I meant upgrading the battery on the p85+

    I doubt that resale value is an issue for someone making an investment to keep their existing car. Quite likely the intention is to keep it indefinitely. An issue might be more recovering the cost in insurance replacement value if it were totaled.

    Would Tesla honor any warranty problems?

    25k to go from a 90-> is hardly worth it. Not to mention, they keep your 90 pack!

    Nothing that they could reasonably blame on the high voltage system.

    It could be done by Tesla but they won't do it is what I think you really meant :)

    It will be brand new Model 3 versus buying your car + upgrade pack.

    Tesla won’t do it. You would have to go third party and you would have to rely upon that third party to be telling you the truth about the condition of the battery they are installing. Which in my opinion would be very risky.

    I am in a similar boat, has anyone here in this forum actually upgraded the battery from third party? Please share your experience!!

    Can't see how the math ever works.

    Out of warranty 60D -> P100D modification but thats all I would ever risk 25K on.

    It would seem to me that Tesla will have to offer some form of battery replacement/upgrade at some point once batteries start seeing less than about 60% of their original range. If not this would pretty much be a death knell for EV's in general. Who would want to buy a car that could not have it's powerplant replaced/refreshed?

    But of course this does not help you in this current dilemma.

    Yeah, I don't know about going from 90 -> 100 at $25k.

    If it was 60, 70, 75 -> 100 @ $25k, I would find that to be more acceptable.
