TP4056 1A Li-ion lithium Battery Charging Module With Current Protection Mini USB

This TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection – Mini USB is a tiny module perfect for charging single cell 3.7V 1 Ah or higher lithium ion (Li-Ion) cells such as 16550s that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.

Using the module:

1. Connect mini USB cable for power or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
2. Connect cell to charge to B+/B- pads on the right-hand side of the module.
3. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
4. Important! Disconnect load when charging
5. The red LED indicates charging in progress a green LED indicates charging has finished.
6. Never charge your battery at a rate greater than 1C.

NOTE:

1. Ampere meter can only be connected to a 5v input end of the module.
2. It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh a current of 400mAh is enough.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high like 5.2v the current will be less than 1000mA it is normal. It is protection function auto-subtract the charging current to avoid burn damage to the chip.
6. NO Reverse polarity.
