Description

1.Description:

 It is a Battery Charger Module.It can DIY charging cable,lithium battery charger,if connected to 18650 charger,it can also charge 18650 lithium battery.This product is suitable for charging 1000-3300mAh lithium battery.

2.Feature:

 1).It uses the USB interface pads.

 2).It uses a linear charging structure.

 3).It has a two-color charging indicator (red light means charging,green light means fully charged).

 4).It supports optional reverse polarity protection,output short circuit protection and chip overheat protection.

3.Parameter:

 1).Product Name:Battery Charger Module

 2).Input Voltage:DC 5V

 3).Output Voltage:DC 4.2V

 4).Output Power:0.6A

 5).Applicable Interface:UAB A male

 6).No-load Power Consumption:1.5mA-2mA

 7).Applicable Indicator:onboard two-color charging indicator

 8).Work Temperature:-25℃~85℃

 9).Work Humidity:5%~95%RH

 10).Size:22*13.5*3mm

4.LED Indicator Status Description:

 1).When the input is powered and the battery is not connected,the green light is on and the red light is flashing.

 2).The red light is on and the green light is off when the battery is charging.

 3).When fully charged,the green light is on and the red light is off.

 4).When the output is short-circuited,the red light is on,and the short-circuit current is about 0.1A.

5.Note:

 1).The default output current of this product is set to 0.6A,and the upper limit of charging supports 1A,because considering the heat problem,the charging current of 0.6A is more reasonable,and it supports 4.2V lithium-ion batteries with a battery capacity of 1-3Ah.

 2).There is no reverse connection protection for the input or output,the wrong polarity will burn,and the output is short-circuited.

 3).3.7V-4.2V lithium battery special charging board,the battery connection should withstand 1A current,it is recommended that the battery comes with a protective board.

6.Application:

 1).DIY USB charging cable connector

 2).Lithium battery charger

7.Package:

 1).10pcs Battery Charger Module
