CM210 Balance Charger(for 2S LiPo battery) User Manual

Note: To ensure the safe use of CM210, please read this manual carefully before use.

 

1. Safety Precautions

1)Please read this manual carefully before using it to make sure CM210 is safely operated.

2)Please connect CM210 to the power supply first, and then connect the 2S LiPo battery for charging.

3)Keep the charger always away from children and pets.

4)Keep the charger supervised when charging.

5)If the battery has any abnormalities such as leakage, bulging, peeling of the outer skin, color change, or deformation, please do not charge it.

6)Do not refit or disassemble the charger.

7)Do not keep the charger or battery close to a combustible material while in use.

8)Do not try to charge "non-rechargeable" dry cells.

 2. Functions

1)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.

2)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.

3)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.

4)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.

5)Power supply protection: When it is detected that the power supply voltage drops to 3.7V, the current is set to a predetermined current to adapt to various charging heads of different specifications.

6)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.

7)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 an abnormality.

8)Charging time: About 40 minutes for a 500mAH 2S battery.

9)Voltage precision: The full voltage is 4.20V±0.02V.

10) Charging efficiency: Higher than 82%.

4. Instructions for Use

① Insert 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.

② Insert 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 it indicates abnormal charging. Please reconnect the battery and cable to troubleshoot the abnormality.)

③ When all four LED indicators turn solid green, the battery is fully charged, and the charger will automatically stop charging.

④ Remove the battery and then disconnect the power supply.

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 a 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.
