    There is a new lead acid battery, developed by CSIRO, sold by ecolt (suspect spelling), it runs at it's best between 30 and 90 %.
    That point seems to get glossed over at high speed for some reason.

    I think the name of the battery is Ultra. the reason the battery can perform well at 30% is due to it's inbuilt capacitor.
