===== Dual Battery System =====

Challenges - 
  * Different battery sizes requires different terminal current
  * Cross charging
  * Balancing
  * Peak power handling

Big Ideas -
  * VSYS voltage monitor comparetor should be inside PMIC or inside the GreenPak
  * Data based DoU characterization method - benefits
    * Direct comparable among different products/models
    * Standardized characterization procedure
    * Indisputable marketing DoU claim
    * Easy translation to what-if DoU
    * User oriented (vs engineering oriented) DoU communications
