Functions
- Low-power precharge: When it is detected that the voltage of a
single cell of the battery is lower than 3.0V, a small current is
used to activate the battery to restore the battery capacity. - Fast charge: When it is detected that the voltage of a single
cell of the battery is higher than 3.0V and lower than 4.16V, 1.5A
is used to charge the battery. - Trickle charging: When it is detected that the voltage of a
single cell of the battery is higher than 4.16V, 0.8A is used to
charge the battery to make the battery fully charged and avoid
overcharging. - Temperature control: When it is detected that the board
temperature is higher than 75 degrees Celsius, the charging current
will be reduced to 2/3 of the predetermined current to lower the
board temperature, and when it is detected that the board
temperature is lower than 70 degrees Celsius, predetermined current
will be restored to charge the battery. - Power supply protection: When it is detected that the power
supply voltage drops to 3.7V, the current current is set to a
predetermined current to adapt to various charging heads of
different specifications. - Balance charging: When the battery voltage is charged to 4.16V,
if it is detected that the voltages of the two batteries are not
equal, the balance charging is turned on to ensure that the battery
voltages are consistent. - Charging alarm: When there is no current detected for a long
time, charging will be automatically stopped, and the red LED will
flash to indicate abnormality.

4. Instructions for Use
1Insert one end of the standard USB cable into the Type-C input port of the CM210 charger (as shown in the picture below), and then connect the other end of the USB cable to power supply equipment such as power bank, computer, mobile phone adapter, etc.. After the right connection, the red LED indicator will be always on.
2Insert the balance port of the standard 2S lithium battery of A560 into the charging port of CM210 (as shown in the picture below). Then the green LED indicator starts flashing, which means it starts to charge the battery. (Note: The green LED indicator flashes during the charging to indicate normal charging; If the red LED indicator flashes during the charging to indicate abnormal charging. Please reconnect battery and cable to troubleshoot the abnormality.)

6. Voltage Calibration of CM210
Three power supplies are required. Two 5V power supplies at the battery end, with 0.1A current. When the battery end is connected, turn on the battery end power supply. The voltage of the charging end power supply is set to 5V, with 3A current. When the power supply end is connected, turn on the charging end power supply. Then the MCU runs the calibration program inside . When all the green LED indicators are on at the same time and then go out, the calibration is completed
7. Troubleshooting for Common Problems
1. After the charger is powered on, the red light flashes just after inserting the battery or within 1 minute.
A. The current detection resistor is burned out, and the MCU detects that the current is too large.
B. The switch tube is damaged, so it is unable to switch normally. There is no current output or the output current of the power supply is too small.
2. After the charger is powered on, insert the battery and charging works normally for a period of time, and then the red light flashes.
A. The output current of the power supply is too small, or the battery is damaged. Solution: Replace the power supply or battery to charge it again, if the abnormal phenomenon still occurs, the charger is damaged.
