    Hello,

    From the printed manual included in the package (different from manual linked on Amazon, printed manual generally seems better English)  page 5 states this:

    “OUT” arrow: when the arrow behind “OUT” is green and points
    to the left, current is flowing in, the number of AH will increase
    with time; when the arrow behind “OUT” is red and points to the
    right, current is flowing out, the number of AH will decrease with
    time.

    I think there are several reversals in this sentence, I think it should say:

    “OUT” arrow: when the arrow next to  “OUT” is green and points
    to the RIGHT, current is flowing into the BATTERY, the number of AH will DECREASE
    with time; when the arrow next to “OUT” is red and points to the
    LEFT, current is flowing OUT of the BATTERY, the number of AH will INCREASE with
    time.

    I have the Positive battery wire entering transformer loop from connector side, and exiting on the back, i.e. positive wire  from the battery is inserted into the transformer in the direction of the arrow embossed on the transformer. In other words, opposite direction as Image 2.  Paragraph above Image 2 describes the image as showing “discharging mode”.

    Do you agree with my re-write of the instructions?

    Hello David F,

    Thanks a lot for your suggestion.

    But it seems you mistake the OUT” arrow . When the arrow  point to the right, that is discharging status, AH is decreasing.

    On the contrary, AH increases  when arrow point to the left.

    Best regards,

    Hello,

    I suppose definition of charging and discharging depends on which way the current flows through the transformer.  But, maybe break this question into smaller pieces.  The manual says ““OUT” arrow: when the arrow behind “OUT” is green and points to the left,….when the arrow behind “OUT” is red and points to the
    right,” 

    On my unit the  arrow is RED when it points to the left and the arrow is GREEN when it points to the right.  Do you agree?

    Hello David F

    Color is not a key point. As longt as the the arrow of direction is correct,  it is normal.

    Best regards,
