TP4056 Type-C USB Li-ion 18650 Battery Charger 5V 1A Module Charging Board with Protection Dual Functions


Input interface: Type-c USB
The board size: about 2.5 * 1.65 CM
Charge cut-off voltage: 4.2 V + / - 1%
Battery overcharge lifting voltage: 4.00 V
Battery discharge termination voltage: 3.2 V
Battery: over-current protection current 3 A
Maximum charging current output: 1000 ma
The battery discharge protection voltage: 3.0 V
The battery overcharge protection voltage: 4.28 V
The input voltage: 4.35-6V (recommended voltage 5V)


When the battery is connected for the first time, there may be no voltage output between OUT + and OUT-. At this time, connect the 5V voltage and charge it to activate the protection circuit. If the battery is shorted from B + B- and then connected A charge is required to activate the protection circuit. When using a mobile phone charger as input, please note that the charger must be able to output 1A or above, otherwise it may not charge normally
The TYPE C USB socket and the +-pad next to it are the power input terminal, which is connected to 5V voltage. B + is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the lithium battery.
