How to confirm charging current
Make sure to know the maximum charging current of the battery before charging, never use excessive current to charge to damage your battery, which will result in over heat even explosion during the charging process. The charging and discharging rate of battery is usually mar ked with C value. Multiplying the charging C value and battery capacity equals to the maximum charging cu rrent supported by the battery. For example, for a 1000 mAh battery with a charging rate of 5C, the maximum charging current would be 1000*5= 5000mA; therefo re, the maximum charging current is 5A. For a lithium battery, if it is impossible to confirm the supported charging C value, please set the charging current below 1C, for the sake of its (lithium battery) safety. The refe rence relation between C value and charging time: char ging time ≥60 minutes/ charging C value (e.g. it needs around 60~70 minutes to complete charging with 1C). Due to differences in battery conversion efficiency, the time to complete the charging might be extended.
Operating the charger
Power on your C50 Duo charger connecting to a car battery/stabilized power supply, connect the battery, and long press the menu button of the desired channel to enter the task setting menu as follows:
| Task | Charge |
| Chemistry | ULiHV, LiHV, LiPo, LiIon, LiFe, Pb, NiMH/Cd |
| Condition | Charge terminal voltage, delta-peak sensitivity for NiMH/NiCd |
| Cells | LiFe, LiIon, LiPo, LiHV, ULiHV (1–6S); Pb (1–10S); NiMH/Cd (1–16S) |
| Current | 0.2–10.0A |
Charge
Charge Balancing port is strongly recommended when charging LiPo battery, which can make sure to monitor voltage on each cell battery and balance it when charging. Warning beeper will yell before start charging LiPo if in non-ba lance mode (no connecting with balance port).
Current setting range: 0.2–10.0A
Starting/Stopping the task
Once satisfied with your settings select "Start" and press the Menu button of the respective channel to start the task.
You can stop the task in progress anytime. Long press the Menu button of the respective channel and then select "Stop" and press the Menu button.
Advanced settings
Under the standby interface, long press the CH1 and CH2 bu ttons at the same time to enter the advanced setting menu.
Dual task
Dual task Select this setting, the charger will charge two batteries connected to Ch1 and CH2 with the same parameters at the same time. Connect the charger with the power supply and power on; select this setting on the advanced setting menu to set the task parameters.
Paralled task
Select this setting; it could output Max Power to one battery. Find a power splitter or 1/2 power cord, one end connect with the battery, and the other two ends connect with the battery output port. The battery balance port could connect with any of the charger‘s balance port. Connect the charger with the power supply and power on, and connect your battery as required, select this setting on the advanced setting menu to set the task parameters. (Note: The battery has to be connected to the CH1 and CH2 outputs before you try to launch the Paralled mode.)
DC power CH1
DC power CH1 The charger CH1 is equivalent to a DC power supply when selecting this function, with output voltage adjustable from 5 to 24V, and current adjustable from 0.2 to 5.0A (max. 100 W).
Under the advanced setting menu, select the system setting into the system setting menu as follows:
Lowest input voltage: 10–24V
All tasks in operation will be stopped at once and hint warning of low voltage, when the input voltage is lower than the input voltage as set up. It will protect the battery from being discharged when using a car battery as power supply.
Max. Input power: 100–550W
If the input power is smaller than the max. working power (550W), please set up the parameter as the actual output power as max input, to protect the input power and enable the charger to work stable.
