Is it better to charge the battery frequently, or to charge the battery after discharging?

Should I charge the battery often, or charge the battery after discharging? The shallower the discharge, the more cycles. Therefore, according to this theory, frequent charging is beneficial to cycle life. However, due to the price and technical level of a large number of recycled chargers on the market, the charger has a high failure rate, poor reliability and low accuracy. Therefore, sometimes frequent charging will affect the battery life. Recharge the battery after using up. Although the number of charging is reduced, there are always differences between the single cells during the discharging process. There may be some over-discharge and over-discharge of the single power grid. The receiving capacity of the battery charge will be greatly reduced, leading to the failure of insufficient charging. . In addition, since the charger is discharged after charging, the charger will be in a heavy load state for a long time, and the charger is easily damaged. Therefore, combining the above, we believe that it is reasonable to charge the battery when it releases 50-70% of the power, which is good for the use of the battery. Protection board over-discharge protection control principle: DW01MOS tube 8205, for example, when the battery is discharged, the battery voltage will decrease slowly through an external load, and the internal resistance of R1DW01 will monitor the battery voltage in real time. When the battery voltage drops to 2.5V, DW01 will think they are At the discharge voltage of the battery voltage, immediately disconnect the output voltage at pin 1 and pin 10V. In 8205, a switch tube is turned off due to no voltage at 5 feet. At this time, the B- of the battery is disconnected from the P- of the protection board. In other words, the battery's discharge circuit is cut off, and the battery will stop discharging. The protection board is in the over-discharge state and remains in the over-discharge state. P and p-indirect are on the protective board after the charging voltage. After DW01, the over-discharge state is immediately stopped. The charging voltage detects B-, and then the high-voltage output is at the first pin. In this way, the over-discharge control tube has been carried out for 8205 years, that is, the battery's The B-cell is connected to the P-protection board, and the battery is charged directly by the charger.
