Arrgh! Mine is defective. Got that edb mini v3 electronic load and it works perfect. Got to checking the 60w with the multimeter and am getting some weird results. Must be a short or bad component

I am new here and positioned in Helsinki, Finland.Please help me with one question.
I have ordered this device and would like to do something else,
I would like to measure batteries, like you do in your battery tests.Get a chart were you can see V, I, Ah Wh etc.I have a laptop.
What do I need to do that, a datalogger or …something else.Please suggest something not to expensive perhaps in the 100 Euro – 200 Euro line.

Best Regards
Clas E.

Depends on what precision you require, with the above load and a multimeter with computer connection you can do it.
You set a fixed current on the load and then you use the multimeter and computer to log the voltage over time. Because the load is drawing a fixed current, you do not really need to measure it, but can just fill it in.
Excel or some other spreadsheet can be used to process the data and make curves.

This is not the way I do it, but my way is considerable more expensive and requires some programming.

This probably doesn’t answer your question.. But for testing batteries with charting/logging, I’ve been using the ZKE Tech EBD-USB+ (will need to download the EB Tester software from their Chinese website, but software has full English version available), and need battery holder. It’s up to 35-watts only though. I’ve also purchased a short thick micro-USB to alligator clips and a battery holder (I think my wiring and battery holder adds some amount of resistance though… but works OK for my own comparison testing uses). I’m assuming you’ll be testing cylindrical batteries or small lead-acid batteries only since 35-watts means lower ampere current drain (the EBD-USB+ has 4A max, IIRC).

No precesion is needed, this is just close to.So thanks to both of you.

Thanks for your comment.
What I would like to test is how many 18650 battteries will be needed to backup my refrigator in my boat.In theory this is solved but i would like to measure it in practice.
I will take a look in what you suggest.My refrigator takes 40 watts (12 VDC) but it is close to what you suggest .
Thank´s again for your comment but can theese devices get you a printtable outcome.
I think your answer solved my question.Thank you.

Regards
Clas E.

Hey, does anyone know if I need to use the small white connector on the side?
It says V+ and V- which I assume is this voltage sense plug people are talking about right?

Any reason why it can’t just be connected in parallel to the P+ and P- ports which already connect to the battery?
EDIT- nvm I looked at a youtube review and apparently it’s not needed.
