2/3/4 Strings to lift the voltage and fast -voltage fast charging/polymer/lithium iron phosphate/lithium battery drone charging module high power

Support fast charging, you can trick 9V/12V.

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

The charging voltage can be set through the resistance to support lithium battery/lithium iron phosphate battery, etc.

5-20V wide voltage input

Support PD, QC fast charge

The adjustment power of the input voltage 12V can be 18W, and 20V can be 22W.The current is calculated based on the electricity

Age charging full of fast charging instructions, etc.

Built -in temperature protection short connection protection

Three -stage charging of trickle/constant current/constant voltage.

The module faces the wide voltage input, the multi -string of battery output, normally cooperate with the protective board, with indicator lights, 4 is full of indicator lights when it is full. If the protective board is protected, it is normal to stop charging in advance.

Recommended voltage: 4.8-20V

B: Battery negative (protective board P-).

B +: Battery positive (protective board P +).

Use

The module input can be the Microsb interface, the Type-C interface, or one of the direct welding lines. The voltage is 4.5-15V. The battery can be set according to the resistance of the resistance R1 and R2., The battery must bring a protective board, it is better to automatically balance the voltage.If the input is used for fast charging, the two strings can be set at 9V input, and 12V input is set for more than 3 strings. Of course, it is also possible not to set it.

Introduction to other charging voltage settings

Because the module supports a wide range of charging range, the module only provides several common charging configurations. If other charging configurations are required, the R1 and R2 resistors can be configured by themselves. The charging interception voltage can be calculated with the following formula.

Battery charging dead voltage = 1.8V (1+R1/R2)
