6PCS TP4056 Charging Module 5V Micro USB 1A 18650 Lithium Battery Charging Board Power Charger Board Module with Protection Charger Module (Micro USB)

Specification: The input voltage: 5V Input interface: micro USB Charge cut-off voltage: 4.2V + / - 1% Maximum charging current: 1000mA Battery over-current protection current: 3A The battery overcharge protection voltage: 2.5V Product Description: + MICRO USB female and next - pads for the power input, access 5V. B + positive then the lithium battery, B- then negative lithium batteries. OUT + and OUT- connected to the load, such as positive and negative electrodes connected mobile booster plate or other load. Connect the battery to the B + B-, inserted into the USB female mobile phone charger, the red light is being charged, the green light to full. Note: Test current meter in series with the charge sheet only 5V input. Charge current is best battery capacity 0.37C, is 0.37 times the capacity, such 1000mAH battery charging current 400 this is enough. The effect of excessive charging speed backward, rushed over battery voltage out on much! Not too small and too long charging connector wires. Such big connection resistance. Too thin, then rushed over battery voltage out on much. Connected to the battery the best good contact. Otherwise rushed over battery voltage out on much. If the 5V input voltage is high, such as 5.2 or even 5.5, will result in insufficient charging current is 1000mA, this is normal. High voltage chip fever will automatically reduce the charging current, not to chip burned. Chip at work about 60 degrees fever is normal. After the charging current is large. Enter the reverse has no effect on the chip, but the output (battery terminals) reverse will burn the chip, please note that buyers. Package Including: 6 * TP4056 Charging Module
