Peer-to-peer wireless communication network among rechargeable batteries

A battery comprising:

• battery cells;
• a wireless transceiver operable on a peer-to-peer wireless communication network having a plurality of batteries;
• and
• a processor coupled to the battery cells and transceiver, and operable to control the transceiver, wherein the processor is further operable to:
• communicate with the plurality of batteries to designate one of the batteries as a master in the peer-to-peer network and the remaining batteries as slaves,
• measure at least one battery operating parameter for the battery cells, and communicate a health indication based on the at least one battery operating parameter to the master,
• wherein
• when the battery is the master, the processor is further operable to determine, using the health indication from each battery, which one or more of the batteries is the healthiest among the plurality of batteries and direct the healthiest one or more batteries to inform a user that they are the healthiest.
