Description

5V 1A Micro USB 18650 Lithium Battery Charging Board Charger Module + Protection Dual Functions TP4056 This is a miniature battery charger based on the TP4056 integrated circuit. It is ideal for adding an embedded battery charger to your new project. Charge Li-Ion batteries from onboard Micro USB connector from USB or external +5V source. With Micro-USB on board connector, you can directly connect to computer USB port for battery charging. If USB is not available you can use an external source voltage at IN+/IN- pads great for DIY projects Safety Notes: Ampere meter can only be connected to the 5v input end of the module. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough. The connection wire should not be too thick. Make sure the connection points is good. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is a protection function, auto-substract the charging current to avoid burn damage to chip. NO Reversal polarity.
