A good way of charging Li-ion batteries is usually 20-80-20. However, our BMS takes care of limiting upper and lower capacity to some extent and hence it should not matter much if you charge 0-100-0 or 20-80-20.
If you charge 0-100-0, you have consumed 1 full cycle, whereas if you charge 20-80-20 you utilize a partial cycle. Hence the count of cycles will differ based on charging behavior. By 20-80-20, one can stretch the life of battery even longer.
