I bought (an incredible three years ago now) 10 GFB (Ganfeng) 277 Ah cells (which should test higher), to keep on the shelf for second project: a van. I bought an extra two cells because I saw the uncertainty in the supply, and the quality, so I didn't want to end up with 7 good cells and no good way to move forward. I am about to build this 8S battery and now have them sitting on the bench to be top balanced.
How should I choose the 8 cells to use in the battery, putting 2 on the shelf as spares for the future?
