Product Description:
The 24S 14A Intelligent Charge and Discharge Equalizer
(EK-FD14AS24CK) is a device designed for use with 2~24S battery
packs that range from NCM / LFP/LTO(Li-ion/Lifepo4/Lto) and have a
battery voltage between 2V and 4.5V.
It should be noted that the actual current that is produced by the
device is dependent on various factors, such as input voltage, line
resistance, temperature, and battery performance. Additionally, it
features automatic identification of the number of battery series,
which is a convenient feature.
Moreover, the device is equipped with reverse connection
protection, over-temperature protection, over-voltage (4.5V)
protection, low-voltage (2V) protection, and an alarm to prevent
possible hazards. Furthermore, the device will automatically stop
and alarm when the balancing process is completed
There are three types of balancing the device supports, including
discharge balance, constant voltage balance, and charge balance,
which requires an external charger with adjustable non-auto-stop
function. There are two modes to choose from; automatic
identification mode and manual input mode. When using the automatic
identification mode, the device will balance all strings to the
voltage of the lowest voltage string by aligning their voltage
downwards. Alternatively, the manual input mode allows the user to
set the required balanced voltage, and all strings will balance
according to the set voltage value.
The device also features a 7 inch Display that displays balanced
voltage, balanced current, voltage per string, total voltage,
maximum voltage, minimum voltage, average voltage, maximum voltage
difference, and the number of battery strings. Additionally, it
displays the temperature, making it easy to monitor the performance
of the device and the battery pack.

| 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. |
