DESCRIPTION

This module is a small single cell lithium battery charging module which also includes a 1A step-up (boost) converter for powering a large range of applications. The module will charge most types of single cell (3.7) LiPo/Li-Ion batteries from either 4 to 7.5V power supply input, or from a standard 5V USB port/adapter. A battery charge and standby LED is also included for visual indication.

Besides battery charging capabilities this module also includes an adjustable boost converter which is capable of stepping up the attached battery voltage from 4.5 to 24V with a maximum supply current of 2A (see table).

 

NOTES 

  • If powering from USB or 'IN' terminals a suitable LiPo battery must be connected for correct operation of boost converter.
  • Do not connect power to 'IN' terminal whilst powering from the USB connector.
  • Can be used for multimeter, modified lithium battery charging.

 

CONNECTION

  • VIN+ connect 5V solar panel
  • BAT+ terminal can output 4.2V to charging 3.7V 18650 battery
  • OUT+ side can output an adjustable voltage

EXTRA SPECIFICATIONS

  • Input voltage: 4.5-8V
  • Input Voltage (USB): 5V
  • Output voltage: continuous adjustable 4.5-24V (Counter clockwise to boost voltage)
  • Charging voltage: 4.2V
  • Charging current: Up to 1A
  • Discharge current: The maximum 2A
  • Battery type: Single cell LiPo 3.7 / Li-Ion 18650, 18500, 14500
