    Voltage/current trimpot adjust

    I have a generic Yarlan 16s lithium charger. This is set to 67.5 volts but I want it to charge a 15s battery. Inside there are three trimpots and from what I read one can adjust the voltage and current. Rather than trial and error the adjustments, maybe others have done this before. thanks
