XH~M609 Low Voltage Disconnect Switch Cut Off 12V 24V 36V Dial LED Display Over~Discharge Protect for 12~36V Battery

Descrtion:- Programmable battery low voltage disconnect switch for DC 12-36V lead battery and ion battery. It's a protection switch module, not included batteries its.- On-board momentary push on to set the low voltage disconnect and 3 di red LED display the easy to operation- When the battery voltage reach the setting values, the module will disconnect load automatically to avoid the battery from over discharging to prolong the battery lifetime- Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off.Specifications:- Input Voltage Range: DC 12-36V- Control Accuracy: 0.1V- Compatible Battery: lead , ion battery, solar panel battery- Board Size: 57 X 42 X 19mm (L*W*H)Operation Instructions:1. Double-click the + number on, then pre + or - on, set the stop voltage value2. Double click on the-number on, then pre + or - on, set the return voltage value3. Pre the + number on, then pre + or - on, calibrate the input voltage display value4. Pre the - number on, then pre + or - on, set the latency start value T. At the time of the output voltage reaches the start value, ar the delay T, there is a voltage output, the delay time is 0 ~ 10 minutes, the display category is: 000 or 001 or 005 or 0105. Click the + number on to view the stop voltage value6. Click the - number on to view the return voltage value7. The difference in the difference can be set to 48V, minimum can be set to 0.5VWhat is the 'difference value'?The value between the battery voltage to disconnect and the battery voltage to reconnect.For exampleI want the battery to stop outputting when the battery voltage is lower than 11V and re-output when it is over 11.6V. What should I do?Hold on '+' and set the value as 11. The LED starts fing. Ar the fing stops, hold on '-' and set the difference value as 0.6V.Q & A:Q: How long will this module charge the car battery?A: The module does not charge its, it only turns on and off the charge.
