2/3/4 series lift voltage fast charging / polymer / lithium iron phosphate / lithium battery drone charging module high power

4.5V-15V wide voltage input, and support 1-5 series battery charging.

Charging voltage can be set through the resistor to support lithium batteries / lithium iron phosphate batteries, etc.

5-20V wide voltage input

Support PD, QC fast charging

Adjust the power according to the input voltage, 12V can be 18W, 20V can be 22W, the current is calculated according to the voltage.

Generation charging full fast charging instructions, etc.

Built-in over-temperature protection short-circuit protection

Trickle/constant current/constant voltage three-stage charging.

Module for wide voltage input, multi-string battery output, normal with the protection board to use, with indicator, 4 often full full indicator light if the protection board to protect the early stop charging may lead to full indicator light does not light is normal.

Recommended voltage: 4.8-20V

B-:Battery negative pole (protection plate P-).

B+: Positive battery terminal (protection plate P+).

Usage

Module input can be microUSB interface, type-c interface, or one of the direct welding line, the voltage is 4.5-15V, the battery according to the resistor R1 and R2 settings, it can be 1-5 strings of lithium batteries or lithium iron phosphate batteries, the battery should be with a protection plate, can automatically equalise the voltage is better. If the input is used for fast charging, two strings can be set to 9V input, more than three strings set to 12V input, of course, no setting is also possible.

Other Charging Voltage Settings

As the module supports a wide range of charging, the module provides only a few common charging configurations, such as the need for other charging configurations, you can change the R1 and R2 resistors to configure their own charging cut-off voltage can be calculated using the following formula.

Battery charging cut-off voltage = 1.8V(1+R1/R2)

Indicator light display status

Not connected to the battery, charging, full of light

Charging, charging light, full extinguished

Battery full, charging off, full on

Battery short-circuit, charging 0.25s flash, full full off

Fast charging indicator, Charging VCC7V
