Description

10pcs 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module TP4056
Feature:
Input with MINI USB female base, you can directly use the phone charger to do input to the lithium battery charge, and still retains the input voltage wiring pads.
Can be used for voltage 3.6 3.7V and so on 18650, polymer and other lithium battery charge and discharge protection, single or multiple parallel can also be used
Module application range.
Used for single-cell lithium or multi-section parallel lithium charging, charging port can take power from the USB.

Long service life.
Specification:
Condition: Brand new
Board size: approx. 26 * 17mm
Input voltage: 5V
Charging cut-off voltage: 4.2V ± 1%
Maximum charge current: 1000mA
Battery over discharge protection voltage: 2.5V
Battery overcurrent protection current: 3A
Quantity: 10pcs
Instructions:
1. Test current ammeter can only be connected in series at the 5V input of the charging board.
2. Charging current is best battery capacity of 0.37C, is 0.37 times the capacity, such as 1000mAH battery charge current 400 is enough. Too fast to charge the effect of fast, red finished the battery voltage out on the more.
3. The charging connection wire can not be too long. So that the connection resistance is large. Too thin words out of the battery voltage out of the more.
4. Good connection with the battery is good. Or rushed out of the battery voltage out of the more.
5. If the 5V input voltage is high, such as 5.2 or even 5.5, will cause the charging current less than 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. Input reverse does not affect the chip, but the output (battery side) will burn back the chip.
