The Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK) is a useful device for 2 to 24S battery packs that use NCM / LFP/LTO(Li-ion/Lifepo4/Lto) technologies and have a battery voltage between 2V and 4.5V. As the actual current is dependent on several factors including input voltage, line resistance, temperature, and battery performance, it is important to have a device that can contribute to balancing the current.
One of the key features of the Intelligent Charge and Discharge Equalizer is its ability to support automatic identification mode and manual input mode. The automatic identification mode is useful as it is based on the lowest voltage string, which can then be balanced to match the voltage of the lowest voltage string (voltage is aligned downward). The manual input mode is also beneficial in that it allows users to set the required balanced voltage and have all the strings balanced to reach that voltage.
In addition, the Intelligent Charge and Discharge Equalizer also ensures reverse connection protection, over-temperature protection, over-voltage (4.5V) protection, low-voltage (2V) protection, and alarm. It also features discharge balance, constant voltage balance, and charge balance (however, an external charger with adjustable non-auto-stop function is required).
Finally, users can monitor their battery pack on the 7 inch display, which provides valuable information such as balanced voltage, balanced current, voltage per string, total voltage, maximum voltage, minimum voltage, average voltage, maximum voltage difference, number of battery strings, and temperature.
The voltage measurement range of this device is 1V~4.5V, with a measure accuracy of ±(0.08%+0.06%FS). In terms of current setting, it has a range of 0.1A-14A, which can also be adjusted.
The discharge balance method used in this device is the PWM pulse discharge method. In terms of charging assistance, an external charger is needed, and the charging port can withstand voltage up to ±DC130V.
The device has an automatic identification feature for equilibrium voltage. The interface can withstand voltage from B- to B24 without voltage -120V~+120V.
The power supply required for the device is DC12V5A.

| Balanced voltage mode | There are two modes: automatic identification mode and manual input mode. The automatic identification mode is based on the lowest voltage string, and all are balanced to the voltage of the lowest voltage string (voltage is aligned downward). The manual input mode is to set the required balanced voltage, and all are balanced to the set voltage value. |
| Optimum charger voltage | Optimal charger voltage (V) = (balance voltage (V) * number of strings) + (number of strings * 0.01V); Charger current is less than or equal to the balance current. Charging current is less than or equal to 10A. Exceeding 12A will damage the device. When charging balance, please disconnect the charger immediately after balance is completed. |
| Display content | Balanced voltage, balanced current, voltage per string, total voltage, maximum voltage, minimum voltage, average voltage, maximum voltage difference, number of battery strings, temperature |
| Operation Instructions | After power on, the default mode is automatic identification. After connecting the wire, press the "Start" button or the "Equilibrium" button on the chassis to automatically identify and start balancing. Manual input mode, press "Manual input" to enter manual input mode,Then press "Equilibrium Voltage (V)" to open the numeric keypad and enter the balance voltage (2.0v-4.5v) to confirm, then press the "Start" button or the "Equilibrium"button on the chassis to start balancing. Press "Maximum Balance Current (A)" to enter the current setting, the range is 0A-14A. |
