3.7V liter 9V 5V multimeter modified 18650 lithium-battery charge boost discharge integrated adjustable module 2A

All circuits connected before connecting the battery

Cannot be operated with electricity

Damage is not guaranteed to buy before seeing

Use before debugging good default output 9V or so

Input voltage 4.5-8V

Output voltage continuously adjustable 4.3-27V

(4.3V above 27V below any voltage can be output to adjust

Counterclockwise Boost)

Charging voltage 4.2V charging current is a large 1A

Discharge current is large 2A output current to their own calculation

Output reference is high current 5V 1.4A , 9V 0.8A, 12V 0.6A

Quiescent current approx. 0.5 mA

The overshoot protection has

over discharge protection no (also can be said to have, 2V cut-off boost

But do not block the output output or 2V)

Cut-off boost 2V depending on whether additional protection plate

Size 3.3X2.3X0.9

For example, VIN terminal connected to 5V solar panel BAT terminal can output 4.2V to 3.7V 18650 battery charging

OUT terminal can output an adjustable voltage need how much their own adjustment can be

Can be used for multimeter modified lithium-battery charging
