Product Description:
The EK-FD14AS24CK is an Intelligent Charge and Discharge Equalizer
designed to work with 2~24S battery packs containing
NCM/LFP/LTO(Li-ion/Lifepo4/Lto) with a battery voltage between 2V
and 4.5V.
The current that the device uses is determined by the input
voltage, line resistance, temperature, and battery performance, so
it can adjust accordingly.
For added protection, this device has reverse connection
protection, over-temperature protection, over-voltage (4.5V)
protection, low-voltage (2V) protection, and an alarm to alert
users to any issues.
And once the device has finished balancing your batteries, it
automatically stops and alarms.
This device can manage discharge balance, constant voltage balance,
and charge balance, but you'll need an external charger with
adjustable non-auto-stop function to use it.
In terms of modes, there are two available: automatic
identification mode and manual input mode. The automatic 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 lets you set the required balanced voltage
and will balance all strings accordingly.
The EK-FD14AS24CK also has a 7-inch display showing balanced
voltage, balanced current, voltage per string, total voltage,
maximum voltage, minimum voltage, average voltage, maximum voltage
difference, number of battery strings, and temperature.

| 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. |
