Lithium Battery Capacity Tester ATORCH DL24MP - 150W 25A 

For those who still don't understand the video. The cut-off voltage in a cell of this SAMSUNG INR 21700 40T 4000mAh lithium battery is 2.5V according to the technical data sheet. In this case, the cut-off voltage to be regulated on the DL24 would theoretically be 12.5VDC, but this is not how it works in these power tool batteries, that is, the voltage cut-off occurs when the batteries no longer turn on the equipment. This cut-off voltage on equipment is 15.5 VDC to 15.00 VDC on 20 V or 18 V battery-powered tools. For example, a fully charged 18 V Bosch battery is approximately 21.03 VDC. When fully discharged on Bosch 18V tools, it cuts the power supply at 15.0VDC, that is, this is the real cut-off voltage of the already assembled 8Ah battery. He did everything correctly in the video, including regulating the discharge current, which is 800mAh, on this SAMSUNG INR 21700 40T 4000mAh cell. As the pack of these batteries is 5S2P per series of each 5 cells of 4000mAh we will have a discharge of 5 X 800mAh = 4000mAh. Congratulations on the video.

It's a nice video where everything is together (assembly, testing) for a device I'm considering buying. Thank you.

All those Parkside Battery Projects is GOLD!!!!!! Thank you majstore 💛💙💛💙💛💙

Thats good idea, be nice if some one would make up this as a kit, they would sell thousands of them. Thanks for your post.

Old Tupperware food storage boxes work great to build stuff like this. they are tough yet easy to cut and the cover can still pop off for easy access inside.

Спасибо! Вот это человечище!!!

Excellent

Полезная штука. Корпус зачётный.

Great project! I purchase one and waiting for deliviery. Thanx for stl case! Regards from poland ;)

cool cool cool!!! I didn’t even know about such a load!!! I wanted to order it with a computer cooler, but this load is steeper! thanks for this video! I'll buy the same load! (the standard power supply is terrible, you need to replace it with a normal one) thx man!!!! Goood video!!!! Omg it’s awesome!!!!

I'm surprised how easy that AC adaptor came apart 😮 I'd would have used a grommet for the power cable input though. Tie wraps don't secure it enough.

гарна робота !

Excellent power meter, it draws exact 4A 😮 It would be interesting to measure a car battery for example 🤔

That's one nasty blister, dude.

Он же четырёх входовые гнёзда запаралелил! Зачем разъем оставил на подключение?

Hello, where did you get the housing for your DL24m? Greetings Bernd

Nice job! 🔥

Useful 👍👍👍

full capacity (8Ah) is between 4.2V and 2.5V not 3.1V as was on movie.

Can't find the case, I can only find the DL24 unit :(

I feel so stupid. I can't get this setup. i have 8,[ Unmatched ], 105, 3.2 volt, Ah lifepo4 cells, and all I want is to write a known capacity number on each of these.

tienes algun archivo para imprimir la carcasa ?

Where i can found this case

السلام عليكم حاولت اتواصل معك عبر البريد الالكتروني دون اي رد اتمنى ان تجيبني

كم ثمنه

👍👍👍👍👍

Zły pomysł z tym połączeniem wyjść prądu i pomiaru napięcia. Teraz nie pokazuje prawdziwego napięcia na testowanej baterii. Zepsułeś jedną z zalet tego urządzenia.
