    Hello,

    Do you only turn it clockwise ? That is to increase output voltage. Please turn it anticlockwise until preset value is lower than input voltage.

    Best regards.

    in reply to: After fully charged the Battery Capacity is 220AH not 20 AH #84149

    Hello Noel Ong,

    To check what wrong it is, would you like to show operation details  by video so that we can find out the cause?

    If you need to revise AH and FU value, please do that before  charging battery.

    Best regards.

    Hello Bjorski,

    Please check if it is this item, https://www.amazon.com/dp/B07759SLYP?ref=myi_title_dp&th=1

    It calculates capacity percentage by monitoring battery voltage.  F4 is for 12.8v LFP battery, if your battery type meet that, it should show correct percentage. Or please choose custom setting, menu “3–“.

    Best regards.

    Hello Jim Young,

    Is it this item? https://www.amazon.com/dp/B00C0KL1OM?ref=myi_title_dp&th=1

    How large is the output voltage now? And did you turn it clockwise?

    Best regards.

    in reply to: Adjusting Capacity to match battery current state of charge #83998

    Hello,

    Please confirm if it is this item,#200219, https://www.amazon.ca/dp/B01MZIAJI0?ref=myi_title_dp

    The capacity percentage =(actual charging or discharging capacity /preset AH value)*100%

    It can only work when you set OAH (over-capacity protection).

    OAH setting: Press button Up or Down  to move yellow cursor to OAH, then hold the OK button to enter parameters setting. After setting, please press OK to save setting.

    Best regards,

    DROK

    Hello Randy,

    Please confirm if it is this item,  https://www.amazon.com/dp/B07YWVCBRN?ref=myi_title_dp

    You can put any cable through current sensor. If current follows the direction of arrow on sensor，it is discharging status, capacity will decrease. Otherwise，capacity will increase.

    Hello Afif Rakhman,

    If quantity is small,  factory need to charge development fees. So if you just order one or two, the cost is very high.  Would you like to pay it?

    Best regards,

    in reply to: DROK Battery Monitor #2001710003 with 3 lithium batteries how to program #83807

    Hello fred,

    Please refer to  rated battery voltage instead of battery cell quantity.  In this program , one cell of lithium iron phosphate  is 3.2v, assume your battery is 12v,  you can select “F4″(3.2V*4) in menu”1–“.

    If  there is no suitable battery specification in menu 1, please program menu “3–“, custom setting.

    For more deails, please refer to instruction, https://m.media-amazon.com/images/I/911LJfacaVL.pdf

    Best regards,

    Hello,
    Did you find available channel in “SFH”?
    If you have two items, please power on one module and  display only, then search communication channel in SFH. There are value 0 -128, please find out which SFH value  can make it displays voltage. At last, just choose that value in “FCH” menu.
    Best regards.
