Onyehn Low Voltage Cutoff Module, 12V 36V Dc Voltage Protection Module Digital Low Voltage Protector Disconnect Switch Over Disc

How To Use: The First Time A New Battery Is Used, The Rated Voltage Value Is Close To The Actual Value, Judgment To Stop The Discharge Voltage. A Reasonable Discharge Voltage Value Can Be Obtained According To The General Voltage Calculation Method Of The Battery. When The Old Battery Is Used, The Actual Voltage Value And The Rated Voltage Value Are Quite Different, So You Need To Measure The Stop Voltage Value In Actual Use. Battery Charging Usually Uses Slow Charging (The Voltage And Current Of Fast Charging Are Relatively Large, And The Battery Is Easily Damaged.) The Charging Voltage Of Slow Charging Is 1.2 Times The Rated Voltage, And The Charging Current Is Adjusted To About 2/10 Of The Rated Capacity Current Of The Battery. For Example: The Charging Voltage Of A 6V 50Ah Battery Is About 7.2V, Adjust The Charging Current To 10A. For Example Set Lower Than 12.5V To Stop, Higher Than 14V To Start: Set The Protection Value: Press ''+'' Once To Display The Protection Value, Double-Click ''+'', The Decimal Point Flashes, Press ''+, -'' To Change The Value At This Time, And Change It To 12.5. If There Is No Operation For 3 Seconds, The Module Will Automatically Save And Exit The Setting Mode. Set The Return Difference Value: Press ''-'' Once To Display The Return Difference Value, Double-Click The ''-'', The Decimal Point Flashes, Press ''+, -'' To Change The Value At This Time, And Change It To 1.5. If There Is No Operation For 3 Seconds, The Module Will Automatically Save And Exit The Setting Mode. ----------------------------- Trouble Shooting ----------------------------- Trouble: Set This Up To Test A 3S Li-On Pack On A 10 Watt Led The Display Lit For A Couple Minute Then The Module Went Dead Never Worked. Reason: The Module Is Only Suitable For A Single Battery, Not For Battery Pack. Solution: Please Connect With A Single Battery.
