Thread: Logging battery voltage against time under load.

  1. #1

    Default Logging battery voltage against time under load.

    Hello,

    I have recently acquired a Fluke 289 DMM and would like to make full use of is by logging a battery's voltage under load. I want to measure the change in voltage against time of an AW 18650 battery while powering a flashlight. Does anyone know how to do this safely? I know how to make current measurements, but have never tried measuring voltage while providing current to a flashlight. A diagram or a simplified description of the setup would do.

    Thanks!

    Never mind, I have found out how to do this. Turns out its exactly the same as measuring the battery voltage when it is disconnected.
