Ličio baterijų krovimo modulis 1A Micro USB TP4056MIK modulis su apsauga PPK270

Current regulation:

Features:

• Use mature charging chip TP4056,simple peripheral circuits,good protection performance and high charging accuracy.
• Fully machinery automated processing,all patch parts manufacturing.
• Each module will be tested before shipment,high reliability.
• Current can be adjusted,just change the circuit board fixed resistors, can change the output to the 100mA-1000mA, very convenient.

Note:

• Input reverse connection has no effect on the chip, but the output (battery end) reverse connection will burn out the chip.
• Ampere meter can only be series connected to the 5V input end.
• The charging current is best to be 0.37 times of the battery capacity,
• Charging wire can't be too thin or too long.
• Make sure the board has good contact with the battery.
