I would be interested to know what cells they are using in that pack, if they are better cells it could be a steal.

The new pack if it has greater capacity will deliver more maximum power due to higher voltage. It is already experienced by 3.0 owners that current is not changing but the voltage drop due to drawing max power is less, hence power output is higher.Higher power will never happen, the PEM runs hot as it is. The additional amps would cook it if it wasn’t already regulated, the fact the PEM houses everything means you have to keep things pretty stock as you can’t just add a model S dual charger, you are stuck with what you have.
That is a nice bonus with the 3.0 battery. The lower sag directly relates to higher punch at higher speeds. The 3.0 shaved 2 tenths of a second off my 1/4 from a fresh original battery and 4 tenths from an 8 year old pack.Indeed, when I noted desire for higher power/lower impedance, it relates to voltage retention under load. It will lead to improve kW retention and also cooler batteries under load without affecting PEM negatively. Actually, it may lead to less current going to PEM per kW as a higher V is maintained under load thereby allowing the PEM to run cooler also.
Agreed that no one will remake LiCoO2 18650 as per redesign now. So if we receive a new pack of original chemistry design, it is likely NOS. Which I would question using.
The 2008 Roadster 1.5 PEMs are solid aren't known to fail.
