3.7V liter 9V 5V multimeter modified 18650 lithium battery charging boost discharge integrated adjustable module 2A
Debug well before use, the default output is about 9V
Input voltage 4.5-8V
Output voltage continuously adjustable 4.3-27V
(Any voltage above 4.3V and below 27V can be output. You can
adjust the voltage by yourself to adjust the voltage counterclockwise)
Charge voltage 4.2V Charge current Max 1A
Discharge current Maximum 2A Output current should be calculated
by yourself
Output reference maximum current 5V 1. 4A , 9V 0.8A, 12V 0.6A
Quiescent current is about 0.5 mA
Overshoot protection Yes
Over-discharge protection No (it can also be said that there is, 2V cut-
off boost but does not block the output, the output still has 2V)
Cut-off boost 2V, depending on the situation, whether to add a
protection board
Size 3.3X2.3X0.9
For example, the VIN+ terminal is connected to a 5V solar panel, and
the BAT+ terminal can output 4.2V to charge a 3.7V 1 8650 battery
OUT+ terminal can output an adjustable voltage, you can adjust how
much you need
Can be used for multimeter modified lithium battery charging
