Yep. Not understanding can lead to not good results. Agree with you completely @Bob B. However, understanding can make it so the intermediate and final results make sense to you. Ohms law is your friend.I agree with pretty much all of that .... but would add that one of the things that causes the cells to be damaged during top balance is loss of patience .... so lets crank up the voltage on the power supply a little to speed things up.
The other thing is .... hey, I'm not getting anywhere near as much current as I should be .... so, lets crank up the voltage a little to get more current.
So ..... the crappy leads can definitely affect the outcome.
I was having problems with getting the current I should be from my power supply .... replacing the crappy alligator clips pretty much doubled my current.
