High-Capacity 322Wh Rechargeable Battery
The EP330-24V features a rechargeable lithium-ion
battery rated at 12.8Ah at 25.2V nominal,
providing approximately 322 watt-hours
of stored energy.
This large capacity makes it useful for equipment
that requires extended operation away from AC
electrical outlets.
The battery is equipped with an integrated handle,
power switch, charging port, LED battery-level
indicator and built-in protection circuitry.
Battery controls and connection points
Portable and Compact Battery Design
The battery measures approximately
6.8 x 4.3 x 3 inches
(175 x 110 x 75 mm) and weighs approximately
4.1 lb (1.86 kg).
Its built-in handle makes it convenient to carry
between locations or move between compatible
power applications.
Flexible Battery Positioning
The battery can be placed in several different
orientations, allowing greater flexibility
when positioning it near equipment or within
a portable power system.
Constant 24V DC Output — Why It Matters
The battery's direct output voltage changes
as it discharges. When fully charged, the
battery voltage may reach approximately
29.5V, then gradually decrease
toward approximately 20V.
Many 24V electronic devices require a more
stable voltage than a battery can provide directly.
The included 24V DC-to-DC power converter
maintains a constant 24V output
within its rated operating conditions, even
as the battery voltage changes.
Important Advantage:
The EP330-24V delivers constant 24V power
through its converter, making it more suitable
for voltage-sensitive 24V equipment than
connecting directly to a variable-voltage battery.
Battery Voltage and Discharge Characteristics
The battery's nominal voltage is approximately
25.2V. Its voltage decreases gradually during use
until the battery protection system disconnects
the output at approximately 20V.
The discharge curve below illustrates the
typical voltage change during battery operation.
Typical battery voltage versus discharge capacity
Direct Battery Output Warning:
If using the battery without the DC converter,
your equipment must accept the full battery
voltage range of approximately 20V–29.5V.
Equipment requiring constant 24V should use
the included DC-to-DC converter.
High-Efficiency 24V DC-to-DC Converter
The included converter is designed to deliver
24V DC output up to 5A,
providing a maximum output of approximately
120W.
It supports a wide 9V–32V DC input range,
making it useful with compatible battery systems
and other DC power sources.
With conversion efficiency greater than 90%
under specified operating conditions, the
converter helps reduce wasted energy during
DC voltage conversion.
Converter Size and Weight
- Dimensions: Approximately 78 x 36 x 24 mm
- Weight: Approximately 180 g
- Input Voltage: 9V–32V DC
- Output Voltage: Constant 24V DC
- Maximum Output: 5A / 120W
Converter Input and Output Connections
The converter input uses a
5.5 x 2.5 mm female DC connector.
The input wiring can also be used for a
direct-wire connection when properly installed.
The converter output uses a
5.5 x 2.5 mm male DC connector
with center-positive polarity.
Input Polarity
For direct-wire installations:
- Red Wire: Positive (+)
- Black Wire: Negative (-) / Ground
Critical:
Always connect positive to positive and
negative to negative. Reverse polarity may
damage the converter, battery or connected equipment.
24V Output Connector
The converter output uses a common
5.5 x 2.5 mm male DC barrel connector
with center-positive polarity.
This connector is compatible with many DC-powered
devices, provided the voltage, polarity and
power requirements match.
Optional Connector Tips
Some electronic devices use different DC connector
sizes. BiXPower offers interchangeable connector
tips that can adapt compatible power cables to
other connector types.
Always verify the correct connector dimensions,
polarity and electrical compatibility before use.

Estimated Battery Runtime
The EP330-24V stores approximately
322Wh of energy.
Actual runtime depends on the connected device's
power consumption, converter efficiency,
battery condition and operating temperature.
The following estimates assume approximately
85% of rated battery energy is delivered
to the connected equipment after conversion
and other operating losses.
Estimated Runtime Formula:
Runtime (hours) = 322Wh x 0.85 / Device Power (W)
These are illustrative estimates rather than
guaranteed operating times. Actual runtime
can vary significantly.
