Finally, after testing almost all of the cells used in a mod available from the original manufacturers I'm ready to create graphs directly comparing cells against each other down to a certain cutoff voltage. Cells will be grouped into three categories; 10A, 20A, 30A. A lot of the cells will be in more than one category. For example, the 25R will be in the 10A and 20A category. These graphs can be used to select the cell with the highest voltage under load, and/or longest run time.
But, what cutoff voltage to use? This is where I would like your input. We don't want it at the high end because anyone who goes below that will have that information chopped off. We don't want to go too low because the shapes of the curves change and comparing at voltage higher than the cutoff will be tough.
Soooo...somewhere in the middle to low end will probably be the best in my opinion. Nothing chopped off and the relationship of one cell to another will still be maintained even if the cutoff is lower than some people want.
Somewhere between 3.2V-3.4?
Let me know what you think! These are the graphs you'll be using so they should, hopefully, be set up for you to get the information you need.
Thanks!
