This is a DIY Dynamic Load instrument that can do many things professional instruments can do too.

It supports CC, CV, CP, CR and a Battery Mode to profile cells.

The CC, CV and BT modes are implemented in hardware, the CP and CR modes are regulated by the software.

Some of the key specifications are 100V, 10A, 180W, sense inputs

Reverse Polarity protection, Transient Mode, Current monitoring, 1.5 inch color OLED display, rotary encoder.

Protection for over-voltage, over-current, over-power and over-temperature.

There is a also a face plate (front panel) and back plate (back panel) available:

The project is described on my Blog here: https://www.paulvdiyblogs.net/2024/04/build-diy-dc-dynamic-load-instrument.html

Note that the BOM listed in this Shared Project only has the parts that will be mounted on the PCB.

All other parts are in an extra pdf that is available on the github, because I can't figure out how to upload it here.
