Product parameters:

    The charging process is divided into the following three processes: trickle mode, constant current mode and constant voltage mode. When the battery voltage is lower than 3V, the charging module is in trickle mode and the charging current is 300mA.When the battery voltage is greater than 3V, the charging module enters the constant current mode. At this time, the battery is charged at full speed according to the set target current, and the power can be about 21W. When the battery voltage rises to the charging target voltage (such as 4.2V), the charging module enters the constant voltage mode, and the current gradually decreases while the battery terminal voltage remains unchanged. When the charging current decreases to the charging cutoff current, the charging ends. If the battery voltage drops to 0.1V below the target voltage, it will automatically start charging again. (Note: If the voltage exceeds 4.2V, it is normal, and the battery will not be charged. When the voltage is 4.2V, the light is still flashing, which means that the battery is not fully charged.

Note:

1: the motherboard external battery line needs to be able to pass 10A current, at least with more than 1 square copper wire, ordinary line to use 1.5 square. It doesn't have to be too thick, but it can't be too thin, because it's a safety hazard. (Because of the high current at the battery end)

2: the motherboard comes with a protection chip, the battery can not be added to the protection board, if you please remove the protection board, direct our motherboard connected to the battery. (because of its own generally can not be too large current, the output power is a large protection)

3: the use of alligator clip motherboard test partners, please do not charge the phone, do not ask why, in short, can not be used in this way. Cell phones that need to be charged must be soldered must be soldered.

4: battery with 4.2V 18650/ polymer/ternary lithium battery, large monomer can be, multiple 18650 parall
