Just to make it easier to understand. Here is what happens when you let your batteries die to often.
A partial discharge reduces stress and prolongs battery life. Higher temperature and high currents also affect cycle life. The earlier you charge the unit the more charging cycles you get. Look what happens when you let the batteries go 100% dead... 300 to 500 charges compared to thousands above 50%. So top them off is the best thing to do. One last thing about every 40 charges let the battery go down to almost dead. Not completely and recharge full. That will keep the power gauge reading correctly.
100% DoD 300–500 <------------------- This is why I say never let the lith batteries go dead 100%
50% DoD 1,200–1,500
25% DoD 2,000 - 2,500
10% DoD 3750 - 4700
PS. The reason you do not want to store your lith batteries at low charge is because over a extended period they may be incapable of taking a charge. Under 40% charge it up for storage.
