Model S - new order BTX8 - Should i worry?

[londonmidlife]

Hi - After nearly 2 years of looking i finally ordered a 75D from September 2017.

After making the order i went on EV-CPO and did a lookup on the VIN, which appears to show that it has battery BTX8.

Does this mean it is a later 2017 car using an older battery, and if so does that mean i cannot get it uncorked? Would this be a worry for anyone?

It should be uncorked already. Just ask tesla to check. Battery shouldn’t impact it.

OK thank you - and are there any reliability issues with that battery? i did some googling and there were mentions of the BTX8 being the older one with issues?

I thought that battery has extra capacity (85kwh).

I owned a 75RWD and loved it. It was an amazing car, my first Tesla and waited many many years before I purchased. I can't tell you much about the battery pack, but here's a thread that offers more info on the pack. I can tell you that my 2017 75 was quick for what it was. I believe it was advertised as 0-60 4.3sec.

BTX8 battery-code on a 75D... or is it a 85D

Here in Norway we are starting to see a new option code for batteries: BTX8. The car is listed as "both" a 85D and a 75D. Can it be a 85-battery capped at 75 kWh? Check out this car as an example, you might have to switch the location on the Tesla-pages to "Norway" to see it: Model S 75D...

If I remember right, the BTX8 is a 400v 85kwh software limited to 75kwh. That means you get much better performance and charge rate out of it. I’d love that pack on my 75

That's correct. Faster supercharging, more top end power and ability to charge to 100 percent without worry (though GUI will nag after 3 successive range charges).

No, you won the lottery.

My 75D purchased Nov 2017 has BTX8 but I don't feel it is a fast supercharger. If you add charge rate in kWh to % SOC (e.g. 70 kWh + 40% SOC), it seldom gets >110 and is usually between 100 and 110. Not sure how that would compare with 75D fitted with the more standard battery.

Same but the taper has to be better because there is hidden capacity.
