    Notes:

    Choose the Max1873 R, S, or T version depending on the number of series cells in your battery pack.

    Resistors R5 and R6 are each 100KΩ for battery packs that use 3.7 volt nominal/4.2 volt maximum cells.
    These values must be changed for older battery packs that use 3.6 volt nominal/4.1 volt maximum cells.
    Using the formulas in the Max1873 data sheet gives new values of: R5 = 54.9KΩ and R6 = 147KΩ.

    Use the Charge_Controller Eagle layout file to order the PCB from OSH Park. The cost with U.S. shipping
    is $27 for a lot of 3 boards. Use the Charge_Controller Gerber zip file to order the PCB from JLCPCB. The
    cost with economy U.S. shipping is under $10 for a lot of 5 boards.
