Im sure this has been asked somewhere before but Im looking to put all my lower cells to use. I want to make a 10-20 pack but am unsure how I could go about making it portable. I have several small battery banks and they all have the little circuit board. But would thoes boards designed to charge 3 cells work for 20? Is there a board out there I could buy that could support 20 cells in parallel with an output for usb 2.1a 5v that could charge all 20 cells
