    I present you EVAL v1.0

    The cell size is solved by changing the holder for a tweezers. If I know that it is now prepared for 18650 cells, which is really what we needed, although we were considering changing the TP4056. But we also have little time to develop further. Thanks for the support

    I present you EVAL v1.0

    Thanks for the support. There isn't. Since in this way the system is much more complicated. In addition to lengthening the processing time, since some cells would have to be unloading and others loading. If I am thinking of putting a battery. Or else, make 2 EVALs, one connected to the other...

    I present you EVAL v1.0

    The 96-cell EVAL is composed of: 32 CADE PCB, each board allows to connect 3 batteries. 32x3 = 96 4 HUB8 PCB 1 EVAL PCB where the esp8266 is The good thing about the system that you can connect 1 CADE or all 32 CADES. This is designed so that each one can mount the ones they need. Although I...

    I present you EVAL v1.0

    Before mounting the 96 cell, I have tested with a 12 and 24 cell, but no PCB. The evaluation results have been super good !!!! Those of us who are opting with the EVAL 96 cells also

    I present you EVAL v1.0

    Of course you can evaluate the type of cells, you just have to change the holder. We have put the 18650 holder, since we only have 18650. The initial idea was to put a needle probe, but that meant spending more time creating an iron structure, and we value not investing that time at least for...

    I present you EVAL v1.0

    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...

    I present you EVAL v1.0

    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...

    I present you EVAL v1.0

    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.

    I present you EVAL v1.0

    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.

    Building an unloader charger 500ma or 1A?

    In the end I use a 10W one and if I plan to put a heatsink and even forced ventilation. I have already sent the PCBs to manufacturing, for my downloaded charger, I will surely make it public.
