Specification: Item Type: Battery Charge and Discharge Module Product Material: Printed Circuit Board Product Parameters: 1: Power supply voltage: DC6--40V; Voltage Detection Range: DC 0--60V; Suitable for various batteries below 60V; Voltage Test Error: ±0.1V; 2: Charge and discharge time OP range: 0-999 Minutes. How to Use: 1. First determine the working mode of the relay; 2. According to the working mode of the relay, in the main interface when the module is powered on, it will flash the current working mode default U-1 mode, and then enter the main interface, "Long press the SET button for 2 seconds and then release” to enter the mode selection interface, and select the mode U-1~U-6 by short pressing the UP and DOWN buttons; 3. After selecting the mode such as U-1, short press the SET button to set the corresponding parameters. At this time, the parameters to be set will flash UL1 voltage upper limit, nL1 voltage lower limit, OP conduction time, and press UP, DOWN to adjust the parameter value, supports long press rapid increase or decrease and short press increase or decrease by 1 unit; short press the SET key to set the parameter of the current mode, the process is the same as above; 4. After setting the parameters of the selected mode, press and hold the SET button for 2 seconds and then release it. The currently set mode will flash, and then return to the main interface. The parameter setting is successful, very simple! 5. On the main interface, short press the DOWN button to switch between voltage and time, which is very simple. Mode Selection Interface: Long press the SET button to enter, after the setting is completed, long press the SET button to exit and return to the main interface, very simple! Operating Mode: Voltage Upper Limit: UL1, Voltage Lower Limit: nL1, voltage upper limit must be greater than voltage lower limit UL1&gt;nL1 U-1: Charging Measurement: When the measured voltage is lower than the lower limit voltage, the relay is closed, and higher than the upper limit voltage, the relay is disconnected; U-2: Charging Measurement Time Control: Set the charging time OP; when the measured voltage is lower than the lower limit voltage, the relay is closed, and the OP time starts to count down after the pull-in. When the time is up, the relay is disconnected; when the voltage is higher than the upper limit voltage, the relay disconnect. U-3: Discharge Detection: When the measured voltage is lower than the lower limit voltage, the relay is disconnected, and when the measured voltage is higher than the upper limit voltage, the relay is closed; U-4: Discharge Detection Time Control: Set the discharge time OP; when the measured voltage is higher than the upper limit voltage, the relay is closed, and the OP time starts to count down after the pull-in. When the time is up, the relay is disconnected; when the measured voltage is lower than the lower limit Voltage, the relay is off; U-5: Closed in the Interval: When the measured voltage is between the upper limit and the lower limit, the relay is closed, otherwise it is disconnected; U-6: Pull-in Outside the Interval: When the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay is pulled in, and the relay is disconnected in other cases; Package List: 1 x Battery Charge Discharge Module
