Description
Specifications

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

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
Output reference maximum current: 5V 1.4A / 9V 0.8A / 12V 0.6A
Quiescent current: About 0.5 mA
Overshoot protection: Yes
Over discharge protection: None (also can be said yes, because 2V cut-off boost but does not block the output, output has 2V)
Deadline boost:: 2V, depending on whether added the additional protection board
