1. The use of high-quality materials, quality assurance
2. With overshoot overdischarge reverse connection protection, safer and more secure
3. Input with MICRO USB female socket, you can directly use the phone charger to do input to charge the lithium battery
4. Easy to use
5. Wide range of applications, voltage 3.6 3.7V, such as 18650, polymer lithium battery charge and discharge protection, single or multiple parallel can also be used
Input voltage: 5V
Charge cut-off voltage: 4.2V ±1%
Maximum charging current: 1000mA
Battery over-discharge protection voltage: 2.5V
Battery overcurrent protection current: 3A
Board size: 26.06*14.47 MM
The first time you access the battery, there may be no voltage output between OUT+ and OUT-, then access the 5V voltage
Charge a little to activate the protection circuit, the battery from the B + B- on the short open and then connected also need to charge a little to activate the protection circuit. When using a cell phone charger to do the input note that the charger must be able to output 1A or more, otherwise it may not be able to charge properly
MINI USB female chassis and the + - pads next to the power input, access to 5V. B + connect the positive terminal of the lithium battery, B - connect the negative terminal of the lithium battery. OUT + and OUT - connect the load, such as connecting the positive and negative terminals of the mobile boost board or other loads.
Connect the battery to B+ B-, insert the phone charger to the USB female chassis, charging L1 light, full L2 light on. (When the L2 light is on, L1 flashing fast indicates that the saturation state)
1. The ammeter for testing current can only be connected in series with the 5V input of the charging board.
2. The charging current is preferably 0.37C of the battery capacity, that is, 0.37 times the capacity, such as 1000mAH battery charging current of 400 is enough. Too large charging speed is poor, the battery voltage dropped after charging more!
3. charging connection wire can not be too thin and too long. This connection resistance is large. Too thin, if the battery voltage dropped after charging more.
4. and the battery connection is best contact good. Otherwise, the battery voltage will fall off after charging.
5. If the 5V input voltage is high, such as 5.2 or even 5.5, will cause the charging current is less than 1000mA, which is normal. High voltage chip heating will automatically reduce the charging current, not to the chip burned. Chip in the work of about 60 degrees heat is normal. After all, the charging current is high.
6. input reverse connection on the chip has no effect, but the output (battery side) reverse connection will burn the chip.
