In the description on that page you linked, I found the words:
IMO, if you aren't comfortable with adjustable benchtop supplies, using them as a charger isn't a great idea. If you happen to have one, know how to use it, it will work. But it isn't what it was built for. I guess the other reason would be if you need some odd voltage (or too high like 60V) not found in regular Lithium or R/C chargers.
Thank you I will keep a look out for those words in the future. The best idea to check if the machine is working properly, find the voltage of the cell, let's say it is at 3.4. Set the machine to 3.45/3.5, set the CV mode, and see if the amps drop to 0 when it reaches 3.45/3.5 on that one cell? I have trust issues with all mechanical things, I have to test them out to see if they work as advertised. Just like how most home ovens give up after for 4~6 hours of continuous baking at high temperature . But once I understand how they work, I will know which boundaries not to cross so I can keep on using things for the longest time.
I just don't understand how the concepts work on the machine itself. Will the bench supply automatically take care of it? We set CV, set the voltage at 3.65, have another volt meter checking the battery side, just to be safe. Once the voltage hits 3.65, the bench supply will start reducing the amps on its own until it reaches down to zero (simplified version in my brain on how it is suppose to work)?
Hopefully once I have the cells in my hands, I can ask more relevant questions on how to get stuff done actually, rather than just thinking about it.
It is not a matter of if I am comfortable or not, some things you just have to learn and get used to them in your own way. Later down the road, we can all laugh at the little fears we had when we started . Otherwise life has a way of rubbing our nose in the things we avoid.
