Feature: 1. [Digital Display Design] DC6V‑80V lithium ion batteries can be set up battery charge controller board, using three digit 0.36 inch LED digital tube display, the maximum input voltage of DC80V, if the input voltage is higher than 80V may be permanently damaged. 2. [Multi Application] Charger module for all applicable voltage range of electric bike batteries, car battery discharge protection, over discharge protection for various storage batteries. Protection of input voltage of solar energy, solar panels and wind turbines, etc. 3. [Voltage Correction] Input terminal connected to DC 30V (only recognize the voltage of 30V), short circuit the board in the upper right corner of the display of the two welding points (Calibration) for more than 1 second, the digital display CA.L flashing and then stop, release the two short circuit welding points that correction is complete. 4. [Use] Battery over discharge voltage setting, due to the different loads, the cut off voltage required also varies, according to their own measurement in the actual use of the termination voltage value, provided that the cut off voltage shall be greater than the battery over discharge voltage. 5. [Overvoltage Setting Range] 6‑80V unrestricted (display ‑‑‑), the factory default is not limited. Another overvoltage voltage should be greater than the discharge voltage, such as the setting can not be + or ‑, then check the HV key setting value is appropriate. Specification: Item Type: Charger Module Material: PCB Display Color: Red Display Mode: Three Digit 0.36 Inch LED Digital Tube Supply Voltage: DC6V-80V Output Voltage: Equal to the Supply Voltage, DC6V-80V Maximum Input: DC80V, Note: Input Voltage Higher Than 80V May Be Permanently Damaged Control Accuracy: 0.1V Power Consumption: <1.5W Protection: If the voltage at the input is reversed, it will be automatically protected and there will be no display and no output. (Note: If the input wiring is correct, the output terminal wiring polarity reversal is no protection for the output) Stop setting ≦11V, ≥ 14V start, ≥ 15V stop: First set the high voltage value: press HV once to display the protection value, long press the value to blink, then press + or - to change the value to 15. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set cut off voltage: press + once to display the current cut off voltage, long press the value to flash, release the key, and then press + or - to change the value to 11. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set back difference value: press - once to display the current back difference voltage, long press the value flashing, release the key, and then press + or - to change the value to 3. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Open within the range of 10.5V to 12V, and close others (i.e. stop at low voltage ≦10.4V, stop at high voltage ≧12.1V): First set the high voltage value: press HV once to display the protection value, long press the value to blink, then press + or - to change the value to 12.1. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set cut off voltage: press + once to display the current cut-off voltage, long press the value to blink, release the key, and then press + or - to change the value to 10.4. After no operation for 4 seconds, the module will automatically save and exit the setting mode. Set back difference value: press - once to display the current back difference voltage, long press the value flashing, release the key, and then press + or - to change the value to 0.1. After no operation for 4 seconds, the module will automatically save and exit the setting mode.. Package List: 1 x Charger Module
