    Genuine A123 AMP20 Module! 5kWh, lots of amps

    Model 3 battery cell specs

    I suspect ~.00045 ohm per group or 0.043 ohm for the whole pack. Lower then the model s. That's room temperature burst dcir. I have no sources just speculation ;-)

    Model 3 battery cell specs

    Based on some more speculative estimates on my part, the Model 3 pack is probably capable of more power then even the P100D pack. Perhaps as much as 650kW in short bursts.

    The BEST connectors, period
