    So cool to see you still reviewing this stuff. Been a subscriber for almost a decade back when i was in university.

    Great video, thanks! I use the green screen one in my van to see power from the alternator, it's quite interesting!

    Perfect timing! I was looking at the various models available

    The yellow flashing is to indicate power coming in, this unit is the same as many brands including Renogy with a different layout of the icons on the screen, the flashing is good for when the meter is on a far away wall in a campervan etc, it instantly tells you the unit is receiving power, initially I thought it was a bit annoying but it's quite a good function when you can't see the actual numbers from a distance but can see the flashing, when discharging the backlight stays on on constantly this is also to indicate power being taken out of the battery without having to see the actual display, it's good when camping.

    If you put more turns on the power wire for the H56 sensor coil. Maybe it can trigger at a lower current. So with 10 turns it triggers with small load current. Then the value measured device by 10.

    You can probably hot wire the backlight with a resistor, but it seems like all 3 have pretty big flaws.

    Strange to see a magnetic sensor used for dc current measurement, as you need to null the output when no current is flowing. Can't call it a current transformer as I expect it has a hall affect device measuring the magnetic field in the ferrite core.

    Also, the two devices will be out of sync because one is set to 100mAH and the other 136mAH . I think I like the higher accuracy over big 100mAH jumps

    Two coulometers? What's that in miles?

    Good day Sr. Nice video do you know of any DC to DC boost converter that can boost 3V or 6V to 12V or higher at 15 to 20 amps?

    • @JulianIlett
      @JulianIlett  2 місяці тому +1

      12v at 20 amps would pull 80a from the 3v supply. More if you include losses.

    There's also a TR16 and for a bit more a KH140F. Get buying Julian jajaja

    Thanks for the.video...👍
    The backlight auto off ...of the Green one is terrible!!
    Why can,t you set this in the menu to also always on ?😳
    And the left one is still more annoying..blinking the whole time.! 😳 I hope you can find better ones....than i am interested..not for this crap ..

    Neither seem exactly reliable or accurate, but I would definately put on/off toggle switches on the backlights.

    Didn't you do a test of the Junctek unit some time ago? It would have been nice to see it stacked with these two. I got a pair of them in large part due to your review, but I have yet to install them in my off grid solar system.

    • @JulianIlett
      @JulianIlett  2 місяці тому +1

      I did review the Juntek device. The main difference is that the Juntek doesn't have either of the synchronising voltage triggers.

    The unit does have a b at the end: "The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI)" [via Wikipedia] so the second (right hand) device is arguably named more correctly, and the video title spelling is not correct

    Are you sure that's a coil? Not a ferrite ring with hall effect sensor?

    The junctek Coulometers are much better units very accurate I have one on my 48v 460Ah off grid battery and after more than six months it is within 1% of the battery bms value

    Two highly flawed coulometers.
