You may want to take a look at the DC Electronic Load on this page, it can probably adapted to your test rig. It's a nicely done DIY build. https://www.youtube.com/channel/UCDqryeq1kMDSEQwltWqASrA
I did a lot of cell testing using the West Mountain Radio CBA at 1C to profile all of the cells for racing packs. Then balanced distribution of them across the sub packs.
Also did some high amp testing using lengths of bare 12 ga wire submerged in water, and with the CBA recording voltage & time for discharges and recovery. 26 feet of 12 ga was about 60 amps on a single 3.3v cell. Shorten the 12 ga wire to increase amps. The wire took a 744A load from a test 2P4S pack with no problem.
It's a quick and dirty method but provided the data I was looking for.
