Battery overcharge lifting voltage: 4.00 V

The battery discharge protection voltage: 3.0 V

Battery discharge termination voltage: 3.2 V

Over discharge / Deep Drain protection voltage: 2.5V

Over-current protection: 3A

NOTE:

1. Ampere meter can only be connected to 5v input end of the module.

2. 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.

3. To increase to charging rate, the connection wires must be as short as possible to reduce resistance. The B+ and B- pins are exclusively for lithium battery

4. The connection wire should not be too thick and 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-substract the charging current to avoid burn damage to chip.

6. Don't reverse the output polarity, it may damage your battery.

ATTENTION: For first time uses, kindly put the battery before charging. Also, the module takes time to activate the protection circuit, be patient. For user who uses USB adapter as a charging source, please make sure the supply current is above 1A.
