After observing the X5M DPs, it's not an eCAT which requires the battery to heat it up during cold start. It's due to the fan running 10-15min after shut down. The primary battery is not used for the fan cool down so there's enough amp to start the car.
My 50i had two...
Well damn. The specs online lied.
