Man kanske inte ska ladda så ofta som möjligt men definitivt inte fullt varje gång.
Man ska hålla sig inom intervallen 30-80%. Bäst livslängd får man om man börjar ladda när man nått 65% och laddar till 75%.
Då och då ska man ladda fullt.
Man laddar det fullt för att BMS ska kalibrera och ladda jämn spänning över alla celler.

Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
On the negative side, a lower peak charge voltage reduces the capacity the battery stores. As a simple guideline, every 70mV reduction in charge voltage lowers the overall capacity by 10 percent. Applying the peak charge voltage on a subsequent charge will restore the full capacity.
In terms of longevity, the optimal charge voltage is 3.92V/cell. Battery experts believe that this threshold eliminates all voltage-related stresses; going lower may not gain further benefits but induce other symptoms
