Device management over mesh network

A battery pack includes a case, a rechargeable lithium ion battery cell, a positive terminal, a negative terminal, a data terminal, a battery management system, and an Internet of Things (IoT) module. The data terminal includes at least one data pin configured to receive operational information from a device connected to the battery pack. The IoT module is in communication with the data terminal and the battery management system, and is configured to receive operation information about the device from the data terminal, receive operation information about the rechargeable lithium ion battery cell from the battery management system, and receive operation information about the rechargeable lithium ion battery cell from the battery management system. And transmitting the operational information about the device and the operational information from the lithium ion battery cell over a network interface. The network interface is configured to communicate the operational information about the device and the operatio
