10PCS TP4056 5V 1A Micro USB 18650 Lithium Battery Charging Board Module +Protection Function with Over Charge Discharge Protection

Description: Ampere meter can only be connected to 5v input end of the module. It is better that the charging current is 37% of the battery capacity.For example, the charging current should be 400 for the 1000mAH battery. If you charge to the battery of 1000mAH, current of 400 is enough. The connection wire should not be too thick. Make sure the connect point is good. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip. Connect the battery to the B + B-, inserted into the USB female mobilephone charger, the red light is being charged, the green light to full. Specifications: Input interface: micro USB. Net weight:2g Input voltage : 5V Charge cut-off voltage: 4.2V + 1%. Maximum charging current: 1000mA. Size: Approx. 2.6x 1.7cm/ 1.02x 0.67inch Battery over - release protection voltage: 2.5V. Overcurrent protection current of battery: 3A.

Note that the charger must be able to output 1A or more to do when using a mobile phone charger input, or may not charge. -Please allow 1-3mm error due to hand test. Package Included: 10 x 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module + Protection
