Hello, I present you EVAL in its version 1.0. That I have developed, it is a modular unloader charger.

It consists of 3 PCB:
1 EVAL.
2 HUB8
3 CADE
It supports a total of 96 18650 cells to be evaluated. I am working to support many more.

I give you the link of the video so that you can see it:

It is based on an ESP8266

I await your comments.

All the best

Youtube, you have the option of subtitles. The active ones. Once activated you go to the configuration (the nut) and you click on automatic translation and select the language.

Thank you, I always forget about the translator on youtube. Your project looks impressive If I understand correctly The boards are controlled by a central processor which then sends the data to the software on your computer.

Thanks.
Correct, the ESP8266 is responsible for sending the data to a mosquitto server every second and when it changes step it saves it in a database, where I save all the information of all the cells that I evaluate. So then I can select the ones I want and be able to print a label.

It has been working for a day and it is perfect, it has more than 3000 batteries evaluated.

Shortly we will make a video explaining all the operation of the EVAL.

Hello HoleRaven, at the moment it is in beta version (test), as soon as we have about 5,000 batteries evaluated and we do different tests to verify that the mAh are correct, we will study how to do the sales process, is that okay? Think that we do not want to sell anything that can cause failures or errors.

I have put two power supplies, one of 80A and another of 40A that add up to 120A. The maximum consumption is 96A for the chargers, plus all the electronics. The total consumption goes to about 99A when all the chargers start up. As I said I have put a total of 120A, so that it is left over and has no problems.

New video explaining the 96-cell 18650 EVAL.
We explain the procedure we perform.

I was watching this and was thinking to myself, that all 96 slots are 18650, if for instance someone had larger cells such as 32650 or 46800 obviously you could change the slot out to handle the different size cell, can you program the parameters for the different chemistries such as lifepo4 for instance 2.5DC 3.2SC 3.6FC.
