Type-C/Micro USB 2S 3S 4S BMS 4.5V-15V 18W 2A Li Li-ion Battery Charging Module
This product is a wide application, multi-innovative application design module, has been maturely applied to high-power rechargeable battery applications, with a boost mode of charging.
Support multiple strings of lithium batteries charging, regardless of the input voltage is higher, lower or equal to the battery voltage can be charged to the battery.
Built-in fast charging input protocol, battery charging is divided into three stages: pre-charge, constant current and constant voltage process.
Supports fast charging with a wide voltage input of 4.5V-15V and 1-5 string battery charging.
Charging voltage can be set via resistors to support multiple strings of lithium batteries
Parameter description:
1:Small size, high power, 3A high current, power up to 18W (not exceeding this power).
2:4.5-15V power supply, can be used for 1-5 strings of Li-ion/Li-polymer boost charging.
3:Adaptive charging current adjustment for all USB port charging.
4:Built-in input fast charging protocol, can be configured with 9V or 12V input protocol.
5:Intelligent pre-charge, constant current, constant voltage with short circuit protection.
6:Automatically works in boost or buck mode charging according to input voltage and battery voltage changes.
7:3-colour LED charging status indication indicates charging, full and fast charging.
8:Operating ambient temperature range:-20℃～85℃.
9:Use range:Multi-string lithium charging high power rechargeable battery conversion solar charging
10: Multiple specifications:
2 string full 8.4V
3 string full 12.6V
4 strings full 16.8V
Usage:
Module input can be micro USB interface, type-c interface, or one of the direct solder wire, voltage at 4.5-15V, battery according to the resistor R1 and R2 settings, can be 1-5 strings are lithium batteries or lithium iron phosphate batteries, the battery should be with a protection plate, can automatically equalize the voltage is better. If the input is used for fast charging, two strings can be set to 9V input, more than 3 strings set to 12V input, of course, no setting is also possible.
Introduction to other charging voltage settings
As the module supports a wide range of charging, the module only provides a few common charging configurations, if you need other charging configurations, you can change the R1 and R2 resistors to configure them yourself, the charging cut-off voltage can be calculated using the following formula.
Caution:
*Do not reverse the connection of the battery, or burn the board.
*Before connecting the battery, connect the charging head and test whether the module charging light shows normal.
*The wire must not be too thin, the charging current can not keep up, the wire must be soldered.
*The battery must have a protection plate.
*Module power when the heat will be larger, pay attention to fan heat, do not use not easy to heat are material sealed module.

Questions and answers on the use of:
1. What fast charging protocols are supported by the product?
Answer:The most common QC protocol is currently supported, most fast charging sources on the market are supported.
2. Does the module generate a lot of heat?
A:The heat generation is different according to the charging power, when the charging power is larger, the heat generation will be larger, which is normal.
