    Dual Battery Parallel Module - brought to you by Bicycle Motor Works
    20-72v, 120 amps
    Now you can safely run two battery packs in parallel.  Double your current, double your range, double you fun!
    Size of module: 63mm x 78mm x 25mm
    If you don’t already know, without a protective circuit there are many dangers to using two battery packs in parallel in order to increase your range.  This smart module eliminates those dangers, and it allows you to easily and safely combine two packs of the same nominal voltage.
    When the packs are at the same voltage level, the module will draw equally from each pack to power your motor.  If the packs are at different voltage levels, the module will draw on the higher voltage pack until the voltage levels become equal.  At that point both packs will be combined to power your motor.
    Use two battery packs of equal nominal voltage. You can combine two packs of different capacity (ie: 10ah + 15ah)
