    Interesting. Not sure that Matsushita battery module is compatible with the Tesla temperature management scheme. But does have it's similarities to the Tesla pack. It's also interesting to get these two bits of news so close together.

    I thought it somewhat speculative to suggest that Tesla will be using Panasonic as a supplier. It's possible they might if, like some have said, they had been using Sanyo and since they were bought by Panasonic.... However, it's just a rumor (IMHO) if the only source saying so is an un-named "sources close to the Japanese electronics maker" and no one will go on the record to confirm. I also wonder if they used the plural for source despite having only one.

    I guess we'll know eventually.

    I suppose we would need to at least know the weight of the Model S to calculate how much further a Roadster could travel if installed with these new "better cells".

    We don't need to. 300 / 230 works out to 30.4% more energy storage, so presumably the Roadster would get 244 * (300 / 230) = 318mi ideal range with these new cells. Since the Roadster currently uses 2200mAh cells, the new cells appear to be the 2900mAh variety.

    Also, with the succeeding generation of 3600mAh cells, the Roadster would be able to attain an ideal range of 399 miles. Sign me up!
