Custom 3.7V 4.2V liter 9V 5V multimeter modified 18650 lithium battery charging boost discharge integrated adjustable module 2A

Connect the battery after all the circuits are connected

Non-electric operation

Damage is not guaranteed before you buy

Before use, debug the default output of about 9V

Input voltage 4.5-8V

The output voltage is continuously adjustable 4.3-27V

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

Counterclockwise boost pressure)

Charging voltage 4.2V Charging current large 1A

Discharge current large 2A output current to calculate

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

Static current about 0.5 MA

Overshoot protection is available

Overdischarge protection none (can also be said to have, 2V cut-off boost

But without blocking the output, the output is still 2V.

Cut-off voltage boost 2V depending on the situation whether to add additional protection plate

Dimensions 3.3X2.3X0.9

For example, VIN+ terminal 5V solar panel BAT+ end can output 4.2V to charge 3.7V 18650 battery

The OUT+ end can output an adjustable voltage how much you need to adjust yourself

Can be used for multimeter refitted lithium battery charging
