One thing worth considering is the quality of your BMS board. If you BMS board is a good one, it will balance your battery cells during recharge.
If your BMS does not balance your battery cells, then your battery pack would go out of balance more easily with a deep cycle....ie several shallow cycles would be better.
Hmmm......come to thing of it, even if my BMS balanced the cells, several shallow cycles would be more desireable.
Oh well, i wont go back and change anything in this post, i think it still has some value even if it isnt completely acurate.
