    Hello Gary L Farnham,
    1-U is for votlage fine tuning, if you think the votlage is not correct, you can calibrate.
    For 6- 8 volt batteries, voltage is 48V, so setting should be 12V in “2-b” and 4 in “3-c”
    Here is pdf instruciton from our product page. https://images-na.ssl-images-amazon.com/images/I/A1oWXEg19sL.pdf

    Best regards.

    Hello Gary L Farnham,

    If it is 6 12v battery, we can’t figure out why it is 48V. Could you please check full charged voltage with multimeter？

    Best regards.

    Hello Gary L Farnham，

    Thanks for writing in.

    For 6 12volt batteries, should it be 72V?

    If batter votlage is 48V, you  can set 12V Lead-acid battery in “2-b” and select 4 in “3-c”

    If it is 6 12V batteries(total 72V ), please set 12V Lead-acid battery in “2-b” and select 6 in “3-c”

    Any more questions, please let us know.

    Best regards.

    in reply to: can a voltage booster/regulator also reduce/regulate the voltage/current output. #30092

    Hello Robert,

    Thanks for writing in.

    For boost votlage reglator, output voltage must be higher than input votlage, so it is impossible to be used as voltage reducer.

    And more questions, please feel free to post here or contact us by email.

    Best regards.

    Hello Josh,

    For the old one, solution is the same. You can use 20K，but it  work with hall sensors.

    Hello Josh,

    Thanks for writing in.

    About #200303, we have updated version,  so we are not sure which one you are talking about. Please check whether it is this one. https://www.amazon.com/dp/B07D9B6J78

    You can use 20K，but this item is brushless sensorless motor controller, there is no way to make it work with hall sensors.

    Best regards.

    Dear Sean McCarthy,

    We  passed your problem to our technicians. They said battery stop discharging at 10VDC. But due to voltage loss on load terminal, so the voltage you measure is not the same as battery voltage. Please try to  mesaure battery directly.

    Best regards.
