Specification:
:Charging process is divided into the following three processes: trickle mode, constant current mode, 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 into constant current mode, at which time it charges 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 into constant voltage mode, at which time the current gradually decreases, and the battery When the charging current decreases to the charging cut-off current, charging ends. If the battery voltage decreases to 0.1V lower than the target voltage after full charging, charging will be restarted automatically. (Note: voltage over 4.2V is normal, will not charge the battery, the voltage is 4.2V when the light is still flashing means not yet full, full charge is not only to see the charging voltage)
Note:
:The motherboard external battery line needs to be able to pass 10A current, at least 1 square copper wire, the ordinary line to use 1.5 square. Not necessary too thick, but not too thin, too thin will be a safety hazard. (Because the battery side of the current is very large)
:The motherboard comes with a protection chip, the battery can no longer add a protection board, if there is please remove the protection board, directly our motherboard connected to the battery cell. (Because the self-contained generally can not be over high current, the output power a large protection)
:The use of alligator clips to test the use of the motherboard partners please do not charge the phone, do not ask why, in short, can not be used in this way. Need to charge the phone must be welded must be welded.
:The battery with 4.2V 18650 / polymer / ternary lithium batteries, large single can be, multiple 18650 parallel can also be, can not use lithium iron batteries, disposable dry cell, NiMH, lead-acid batteries, nickel-cadmium batteries, etc.. Batteries can not be connected in series access. The first time the power will be inaccurate power display, etc., please discharge and then fill it up, the first charge can continue to charge for more than 5 hours when the 4 lights are fully lit, will not be charged bad battery, no need to worry.
