Long time storage: When the battery needs to be stored for a long time, it should be charged to nearly 50% of the battery with a voltage of about 7.8V and placed under the recommended storage conditions. Do a full charge and discharge cycle at least once every 6 months (charge first, discharge and then recharge 50%). Application Field: Air quality monitoring equipment, industrial supporting equipment, medical infusion pump lithium battery portable instrument power supply and other fields. Main Features: 1. Multiple protection functions: over charge, over discharge, over current, short circuit over temperature, etc.; 2. Monitor the battery capacity, voltage and temperature through SMBUS protocol, and realize the functions of over-charge, over-discharge and over-discharge protection, etc.
