Just to clarify, you do not need to discharge the battery between cycles, you can recharge the battery from any voltage back to full charge, the only time you need to discharge the battery is when you are done and need to put it in storage... hence "storage mode"
typical storage mode is 3.8v/cell x 4 = 15.2V
so where you're at is fine for storage... doesn't have to be exact, just close
If you set LVC to around 3.4v/cell under load, that will usually get you fairly close to 3.8v/cell at rest to where it may not be necessary to place the battery in...
