Multiple battery power path management system

A method, comprising:

• detecting that a first battery is coupled to a power path management circuit;
• detecting that a second battery is coupled to said power path management circuit;
• in response to detecting that only one of said first battery and said second battery is coupled, selecting said one coupled battery as a power source battery;
• in response to detecting that both of said first battery and said second battery are coupled, selecting one of said first battery and said second battery as said power source battery, said selection based on a battery selection signal provided by a device to be powered;
• and
• configuring a first switch in said power path management circuit such that said selected power source battery is coupled to provide power to said device to be powered.

A system, comprising:

• a power path management device comprising:
• a first battery port configured to couple to a first battery;
• a second battery port configured to couple to a second battery;
• an output voltage port configured to couple to a device to be powered;
• a battery selection port configured to couple to said device to be powered;
• a control circuit configured to select one of said first battery and said second battery as a power source battery, said selection based on a signal received at said battery selection port;
• and
• a first switch configured to selectively couple said first battery port or said second battery port to said output voltage port, said selective coupling based on a first switching signal generated by said control circuit in response to said selection of said power source battery;
• and
• a voltage divider coupled to said first battery and coupled to a low battery indicator port on said power path management device, said voltage divider configured to provide an indication of a low battery condition associated with said first battery.
