    Great video. I have the BL140F and this helped me understand the meter better than the instructions. I use it on my golf cart Thanks for taking the time to do this.

    It would be nice if it could show consumption in Watt-hours. That says much more about the power being used, than Amp-hours.

      Calculating state of charge by counting amp hours is easier. Counting watt hours is non-linear because the voltage is falling.

    Just been on AliExpress, what made you choose this model over the others that are on there?

      I have a couple of other types. I'll make videos on those soon.

      @@WaffleStaffel mine too but it needs replacing i think as all its rubber protection is falling apart.

      i think they do know and are laughing at us. 🙂
      The "dancing American politician moves system", or as we know it in the UK the "al gore rhythm" they use! shows we will buy any old C**P from them.
      At least the battery will always have less capacity than the displays show as i expect it's not measuring its own self discharging affect on it. 🙂

      Almost as daft as making precision measurements with a brand called "Fluke".

    Do you have a link for that 4S cell monitor that you show mounted already on the pack?

    I've been looking for a good coulometer for my bike. It's nice to know the limitations of this one. A little on the pricy side, too. Thanks.

    Why would you prefer this rather than a battery monitor that has watts included?

    So you shouldn't let this sit connected overnight, but then the point is lost - you don't know what the SOC of the battery is. Does it keep the settings of you cut power? I guess so?
