1, the module uses a very mature charging chip TP4056, the external circuit is simple, good protection performance, high precision charger. 2, the module mechanical processing, all-chip parts manufacturing, each module will be tested before the shipment, high reliability. 3, the module current can be adjusted, as long as the circuit board to change the fixed resistance, you can change the output to 100mA-1000mA, very convenient. This module is used for single-cell lithium or multi-section parallel lithium charging, charging port can be taken from the USB Tips: This product is only described description or electronic documents, no technical advice, please beginners carefully shot, thank you understand. 1, the test current ammeter can only be connected in series at the 5V input of the charging board 2, the charge current battery capacity of 0.37C, is 0.37 times the capacity, such as 1000mAH battery charge current 400 is enough. Too large charging speed, the effect will be worse, rushed over, the battery voltage flow out more! 3, the charging connection wire can not be too long. So that the connection resistance is large. Too thin, then finished the battery voltage out more. 4, good contact with the battery connection. Or finished, the battery voltage flow out more. 5, if the 5V input voltage is high, such as 5.2 or even 5.5 will cause the charging current is not enough 1000mA, which is normal. High voltage chip heat will automatically reduce the charge current, not to burn the chip. Chip in the work of about 60 degrees heat is normal. After all, the charging current is large. 6, the input reverse does not affect the chip, but the output (battery side) will burn the chip back, please note
