The invention exposes a lithium cell management system which comprises a processor, a power supply module, a voltage sampling module, a large current detecting and controlling module, a low current detecting and controlling module, a short circuit detecting and controlling, an over current detecting and controlling module, a button awakening and detecting module, a load awakening module, an electric quantity display module, a temperature detecting module, a charger detecting module, a discharge port reverse electromotive force absorbing module, a charge switch and a control module of the charge switch. The lithium cell management system provided by the invention can effectively reduce energy consumption. The system provided by the invention provide a lithium cell pack with over charge protection function, over discharge protection function, over current protection function, short circuit protection function, temperature protection function as well as electric quantity display function and low current detection discharge prohibition function. In case of any situation of over discharge protection, over current protection, short circuit protection, temperature protection, charge or discharge failure or very low current discharge, a whole circuit enters a dormant state.
