the habit:
"I still have charge left , don't have to recharge"
is the very bad one
in general the deeper the discharges the shorter the life of battery.
Of course BMS electronics will cut off when any cell reaches low /2.5V for LiFePo / but still deeper discharges will affect battery life.
That's why batteries should always be oversized for applications.
Example I use on my ebikes 20Ah rated, 17Ah real capacity batteries, but I rearly even use 10Ah, overkill ?
Not at all.
such battery will last and last.
