Lithium battery is a general term. The rated voltage of lithium-ion battery used in mobile phones is 3.6V and 3.7V. The termination charging voltage is 4.2V and 4.3V, and the low voltage protection is 3.3V and 3.2V.
1. The minimum discharge termination voltage of a lithium-ion battery is generally 2.75V. Below this voltage, the battery capacity is likely to be seriously degraded or even scrapped.
2. From Article 1, lithium-ion battery production requires protection lines to prevent the battery from being over-discharged.
3, lithium iron phosphate battery working voltage 3.26V, low voltage protection voltage 2.5V
