Always ensure the input voltage matches the battery's requirements. The module is a switch, not a buck/boost converter.

Max 10A (though 8A is recommended for long-term stability).

This mode is used to protect batteries from deep discharge. The module connects the load when the battery is full and disconnects it once the voltage hits a minimum threshold. Voltage ≥is greater than or equal to UP . Condition to Stop: Voltage ≤is less than or equal to dn . Setting Up the XY-CD60 Entering Setup

In this mode, the module connects the charger to the battery when the voltage drops below a set lower limit () and disconnects it when the battery reaches the upper limit ( UP ). Condition to Start: Voltage ≤is less than or equal to dn . Condition to Stop: Voltage ≥is greater than or equal to UP . 2. Discharging Mode (dn)

The module calculates the battery percentage using the formula:

for about 3 seconds to enter the parameter setting interface. Short press SET to cycle through the parameters: UP : Upper limit voltage. dn : Lower limit voltage. OP : Conduction time (00:00 to 99:59, or "----" to disable). dOP : Delayed conduction time (0–999 seconds). FOP : Forced start time (0–10 seconds) in discharge mode. Use UP/DOWN buttons to adjust the values. Press and hold SET again to save and exit. Voltage Percentage Calculation
