    The smart charger allows a user to switch the charge process of e-bike lithium batteries off earlier: at 40% (winter storage - degradation is minimal), 60% - 70% - 80% (save lifetime and decrease driving range) and 100%. Switching off takes place based on the voltages that correspond with the 4 "save" positions. As this is not 100% accurate, the switching points are recalculated by mea...
