CA-033 Lithium Ion Battery Charging Module 1A 18650 TP4056 Dual Functions

CA-033 Micro Type-c USB 5V Charging Board With Protection Dual Functions 1A Li-ion Lithium Battery Charger Module 18650 TP4056

Module features and parameters:

• The input terminal has a MICRO USB motherboard, which can be directly used as the input to charge the lithium battery.

• And still retain the input voltage wiring solder joints, can be very convenient DIY

• Input voltage: 5V

• Charging cut-off voltage: 4.2V ±1%

• Maximum charging current: 1000mA

• Battery overdischarge protection voltage: 2.5V

• Battery overcurrent protection current: 3A

• Board size: 2.6* 1.7cm

Note:
When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, the
protection circuit can be activated by charging 5V voltage. If the battery is connected from B+ B-, it also needs to be charged to
activate the protection circuit. When using mobile phone charger as input, note that the charger must be able to output 1A or
above, otherwise it may not be able to charge normally.

MICRO USB base and the + - pad next to the power supply input end, access to 5V voltage. B+ connects to the positive electrode of
the lithium battery, and B- connects to the negative electrode of the lithium battery. OUT+ and OUT- are connected to loads, such as the positive and negative terminals of the mobile booster plate or other loads.
