Description

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.

Using the module:

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

NOTE:

• Ampere meter can only be connected to a 5v input end of the module.
• 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.
• The connection wire should not be too thick.
• Make sure the connect point 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-subtract the charging current to avoid burn damage to the chip.
• NO Reverse polarity.
