  What are 18650 lithium battery 2600mah charge protection circuit and discharge protection circuit?

  18650 lithium battery 2600mah charge protection circuit and discharge protection circuit

  1.Charging of 18650 lithium battery 2600mah

  The maximum charge termination voltage of a single 18650 lithium battery 2600mah is 4.2V. It cannot be overcharged, otherwise the battery will be scrapped due to too much loss of lithium ions in the positive electrode. When charging lithium batteries, a dedicated constant current and constant voltage charger should be used. First, constant current charge until the voltage across the 18650 lithium battery 2600mah is 4.2V, then switch to constant voltage charging mode; when the constant voltage charging current drops to 100mA, Charging should be stopped.

  The charging current (mA) can be 0.1~1.5 times the battery capacity. For example: for a 1350mAh 18650 lithium battery 2600mah, the charging current can be controlled between 135mA~2025mA. The conventional charging current can be selected to be around 0.5 times the battery capacity, and the charging time is about 2 to 3 hours.

  2. Discharge of 18650 lithium battery 2600mah

  Due to the internal structure of the 18650 lithium battery 2600mah, all lithium ions cannot move to the positive electrode during discharge. A part of the lithium ions must be retained at the negative electrode to ensure that the lithium ions can be inserted into the channel smoothly during the next charge. Otherwise, battery life will be shortened. In order to ensure that some lithium ions remain in the graphite layer after discharge, the minimum discharge termination voltage must be strictly limited, which means that the 18650 lithium battery 2600mah cannot be over-discharged.
