5 pcs Battery Charger Module 18650 Lithium Li-ion Battery Charger Module 3.7V 4.2V to 27V Adjustable Step Up Module + 5 pcs 18650 Battery Holder with 26AWG Red and Black Cable
The 18650 lithium battery charging module with Micro USB
interface can charge and discharge at the same time, the output voltage is
adjustable, the default output is 9V, it can be widely used in DIY mobile
power supply, PCB power protection board, mobile phone charging.
Specifications: 1.Before use, before debugging, the default output is about
9V. 2.Input voltage 4.5-8V. 3.The output voltage can be continuously adjusted
4.3-27V(4.3V or more, 27V or less, any voltage can be output, you can adjust
the voltage counterclockwise). 4.Charging voltage 4.2V Charging current is 1A.
5.Discharge current 2A output current to calculate(Output reference maximum
current 5V 1.4A , 9V 0.8A, 12V 0.6A Static current is about 0.5 mA).
6.Overshoot protection, yes; over-discharge protection, yes (2V cut-off boost,
but does not block the output, the output is still 2V). 7.Cut-off boost 2V,
depending on the situation, whether to add a protection board.
8.Size:33mm23mm9mm Example of use 1.For example, VIN+ terminal connected to
5V solar panel BAT+ terminal can output 4.2V to 3.7V to charge the 18650
battery. 2.The OUT+ terminal can output an adjustable voltage, which can be
adjusted by yourself. 3.Can be used for multimeters, modified lithium battery
charging. Package includes: 5 x 18650 lithium Li-ion battery charger module 5
x 18650 Battery Holder 1 x 26AWG red and black cable 50 cm each
