Junctek BL105F Coulometer

[@zaprodk]

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

[@JulianIlett]

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

[@va23141]

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.

If only they knew what "Junctek" means to us over in the west. Oh dear!

My phone is a Doogee- _'dodgy'_

[@steve64464]

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

[@TheEmbeddedHobbyist]

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. 🙂

[@JohnBailey39]

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

[@josephcullen2512]

It reminds me of Junkers... A company probably at least named after someone

[@ifell3]

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

[@JulianIlett]

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

[@ifell3]

@@JulianIlett thank you 🧡

[@zaprodk]

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

[@Alexander19350]

yeah same here.

[@JulianIlett]

I've added it to the video description :)

[@ifell3]

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

[@zaprodk]

Prefer it to what "battery monitor"?

[@ifell3]

@@zaprodk yeah as above, has other functions like Watts etc. Say a traditional one you would get from renogy, victron etc

[@WaffleStaffel]

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.

[@muwlgr]

Does it have wifi/bluetooth/usb or other means for PC integration ?

[@zaprodk]

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?

[@JulianIlett]

Yes, it does.

[@paulwright8378]

Good explanation especially when it came to ah

[@ame7165]

all the latin language speakers must be laughing at the word "culometer" 😂

[@JulianIlett]

Well I hope they didn't laugh at Charles-Augustin

[@mikehensley78]

those samplers are so negative! ;)
