The module calculates the battery percentage using the formula:

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

If OP is set, the relay will automatically disconnect after the specified duration, even if the voltage threshold hasn't been reached. This acts as a safety backup.

High-definition LCD screen showing voltage, percentage, and time. Modes: Charging Mode ( UP ) and Discharging Mode ( dn ). Operating Modes Explained 1. Charging Mode (UP)

Double-check the "IN" (Power Source/Load) and "BAT" (Battery) terminals. Reversing polarity can damage the module.

The XY-CD60 acts as a programmable voltage-controlled switch. It does not provide power itself; rather, it controls an onboard relay to connect or disconnect a power source (for charging) or a load (for discharging) based on voltage thresholds you define. Voltage Range: DC 6V–60V.

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)

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
