TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection

Note: This product is available in two different variants of IC (TP4056 and XL4056A/HW-107) with the same working; we will ship it randomly. This TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection 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 and then cut off when finished. Furthermore, when the battery voltage drops below 2.4V, the protection IC will switch the load off to protect the cell from running at too low of a voltage—and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery); however, please check you have it connected correctly the first time. Manufactured under fully mechanized processing. Each module is tested OK before shipment from vyomtics.com, so it has high reliability for the best performance. In conclusion, it is a special design for a single lithium battery charging. TP4056 Other features include the current monitor, under-voltage lockout, automatic recharge, and two status pins to indicate charge termination and the presence of an input voltage. Using the module: 1. Connect micro USB cable for power, or 5V DC, to pads marked IN+ and IN- on the left-hand side of the module 2. Connect the cell to charge to the 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; the green LED indicates charging has finished. 6. Never charge your battery at a rate greater than 1C. NOTE: 1. An ammeter can only be connected to a 5V input end of the module. 2. It is better that the charging current is 37% of the battery capacity. If you charge a battery of 1000 mAh, a current of 400 mAh is enough. 3. The connection wire should not be too thick. 4. Make sure the connection point is good. 5. If the input voltage is too high, like 5.2V, the current will be less than 1000 mA, which is normal. It is a protection function that auto-subtracts the charging current to avoid burn damage to the chip. 6. NO reverse polarity. We have 3 more such charging boards employing same TP4056 chip, which are available at vyomtics.com and they are different according to the onboard USB port and current protection they provide. Features: 1. Led indicator: red is charging Green is fully charged. 2. Current Protection: Yes 3. Inverted polarity: NO. 4. Use the mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy. 5. Fully machinery automated processing, all patch parts manufacturing. Package Includes: 1 x TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection
