5V Micro USB 1A Lithium Battery Charging Module

5V MICRO USB 1A LITHIUM BATTERY CHARGING MODULE

Product information
This Lithium battery charging board uses the ultra-reliable TP4056 charging IC. It provides good protection, performance and high precision charging for 3.7V Lithium Ion batteries. The output current can be pre-set by changing the resistor marked as 122 on the board. The maximum output current can then be set between 50mA and 1000mA depending on the resistor selected. The unit can be used in together with a Mini PFM Control DC 0.9V-5V to 5V USB Step-up Power Supply Module and 1 x 18650 cell to form a 5V/1A Power Bank.

Notes
1.An ampere meter should only be connected to the 5V input of the module.
2.It is better to charge a Lithium-Ion battery at 37% of its capacity e.g. 3200mAh cell should be charged at 1A.
3.If the input voltage is higher than 5.2V, the current will be automatically limited to less than 1A to protect the charge IC.
4.There is no reverse polarity protection on-board.
