The demo is perfect, this man covered every details i was looking for

Voltage to measure capacity really only works well for lead acid. The other battery types maintain about the same voltage until they are depleted, you need to measure the output amp hours and calculate it from the known total capacity amp hours to get an accurate read out of capacity other than "almost empty and fully charged"

literally the best explanation for this battery meter, thanks

Great video, thanks. Also, that power supply is very nice. Mine has a fan and sounds much louder.

[johnnyhoang]

Would have helped out if you showed how/what the different settings are (backlight, inactivity, etc)

Thank you, this video was very useful, the best among many.

Thanks for this video. Was about to buy this battery monitor for my Lifepo4 12v setup. Thankfully your video came up in YouTube. This monitor is not really accurate. 13.6v is the full capacity of most LFP. 13.3 for 90%, 13.2v for 70%, 13.1v for 40%.

Hi, thanks for the presentation.
How would you test old charge packs that charge up to full voltage but do not have the capacity to charge under load? Thanks

[DavidDavisL]

Good job, thank you. Will look around for options like this one.

[WarrenPenner]

Well nicely presented. Clear and easy to understand. Thanks so much for this!

I have 2 12 volt Lifepro4 100Ah batteries for my 24V trolling motor. I need to be able to check how much charge the batteries have left while I'm out on the water. I currently have 2 standard 12v gauges mounted in the front of my boat that I had for my lead acid batteries. I have read that using the voltage only does not accurantly indicate how much power the battery has left. I would like some guidance as I am new to the Lithium batteries world.

What's the maximum S length on the LiFePO4 setting you can do?

[NevadaScrubJay]

I just purchased the DROK Battery Meter 12V, Marine RV Battery Capacity Volt Monitor and the Power Queen Mini Pro 100AH lithium battery for use with a trolling motor. I just fully charged it and my
DROK voltage meter reads 13.8V. My understanding is that a full 12V battery will read between 14.5V and 14.2V. It shows two bars as green and two as yellow. ??? This leads me to believe some of the cells are bad. ??? What am I not understanding? Can a battery improve with a couple discharges and recharges?

I have the exact some one, if you hold the right button on the set menu, what does it mean, mike mate

super Video... auch wenn man kein wort versteht... thx... lg andy...

Hi, I have recently installed this battery capacity meter and have an issue.

My project is as follows:
1) 12.6V Lithium Ion Battery
2) Strip LED light (2.0m)
3) Touch Sensitive On/Off Switch
NOTE: All components are DC Jack compatible and hence plug and play is possible.

When I incorporate the On/Off switch my reading shows 0%

When I exclude the On/Off switch my battery reading is more accurate 35%

What would be the reason for this. Please let me know.

[davidpatton]

Thankyou my friend. You have perfectly taught me how to install and operate this device. Firm hand shake and knuckle bump. :) I am a subsciber and hope to learn more from your efforts.

I have a lithium bike range extender with 36v nominal (42vmax) so it works setting 10. But my question is what are the S modes in the second menu? I set it up to S2 as per I have 256wh does it woks for something I am missing ?

Hi hello Mr Mike, may I ask actually which one is actually more to close or exactly accurate for these type of batteries capacity volt meter?

[TheUnforgiven]

Many thanks. It helps also for similar voltage meters.
