Note: All the cells that are connected to the power bank module should be in a paraller, please don't connect the cells in series as this will damage the power back module and cause a heating issue in it and eventually the power bank module will stop working.

Note: This module is not suitable for running a DC motor,  as the module is not able to handle the high current requirement of a DC motor but it can run a small DC Toy motor, whose current requirement is less than 100milli amp.
