Mini USB
Parameters:MINIUSB input terminal with a female, can be directly input to do with the phone charger rechargeable lithium battery, And still retains the input voltage wiring pads, can be very convenient DIY. It can be used for voltage 3.6 3.7V, etc. 18650, polymer and other lithium battery charge and discharge protection. Input voltage: 5V Charging cut-off voltage: 4.2V ± 1% Maximum charge current: 1000mA Battery over-discharge protection voltage: 2.5V Battery overcurrent protection current: 3A It can be used for charge and discharge protection of 18650, polymer and other lithium batteries with a voltage of 3.6 3. 7V, and single or multiple parallel connections can also be used.
Instructions:Note:When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, the protection circuit can be activated by connecting the 5V voltage to the power-off.The battery is connected from B+ B: if it is short-circuited and then connected, it needs to be charged-powered to activate the protection circuit. When using the mobile phone charger for input, please note that the charger must be able to output 1A or above: otherwise it may not be able to charge properly.The MINI USB socket and the + - pad next to it are the power input terminals and are connected to 5V. B+ is connected to the positive electrode of the lithium battery, and B is connected to the negative electrode of the lithium battery. OUT+ and OUT are connected to the load, such as the positive and negative poles of the moving boost board or other loads. Connect the battery to B+ B, insert the mobile phone charger to the USB time base, the red light is charging and the green light is full.
Current regulation:
Application range:
This module is used for single-cell lithium battery or multi-section parallel lithium battery charging port to take power from USB.Instructions / Precautions:The ammeter of the test current can only be connected in series to the 5V input of the charging board. The charging current is preferably 0.37C of the battery capacity, which is 0.37 times the capacity. For example, the battery charging current of 1000mAH is enough. If the charging speed is too high, the effect will be poor. If the battery voltage is over, it will be more! The charging connection wire should not be too thin or too long. This connection has a large resistance. If it is too thin, it will be more than the battery voltage. It is best to have good contact with the battery. Otherwise, the battery voltage will be washed off. If the input voltage of 5V is high, such as 5.2 or even 5.5, it will cause the charging current to be less than 000om. This is normal. When the voltage is high, the chip will automatically reduce the charging current, and the chip will not burn out. It is normal for the chip to heat up to about 60 degrees in the work. After all, the charging current is large. Input reverse connection has no effect on the chip, but the output (battery end) will reverse the chip, please pay attention to the buyer.
