It offers the same battery capacity, voltage
characteristics and internal battery performance
as the BX2494B, with a convenient barrel connector
for compatible lower-current applications.
With 320 watt-hours (Wh) of stored
energy and a 25.2V nominal output,
this rechargeable lithium-ion battery provides
portable power for equipment designed to operate
across approximately 20–29.7V DC.
The battery itself supports up to
10A continuous discharge and
15A burst discharge for up to 10 minutes.
However, the CP300's installed barrel connector
has a lower recommended current limit.
Important – CP300 Output Current Limit
The CP300 uses a 5.5 × 2.5mm barrel connector
with a recommended maximum continuous
output current of 6A, provided the
complete connector and cable assembly is
appropriately rated.
For applications requiring more than 6A
continuous output current, we recommend the
BiXPower BX2494B battery with bare-wire output
and appropriately rated wiring and connections.

25.2V Nominal Output – Actual Voltage 20V to 29.7V
The CP300 is a 24V-class battery,
but its actual nominal voltage is
25.2V DC.
When fully charged, the battery can provide
approximately 29.7V DC.
During discharge, voltage gradually decreases
toward approximately 20V,
where the battery's protection circuitry
may disconnect the output.
During much of its discharge cycle, the
battery may operate around 24–26V,
depending on load and state of charge.
Illustrative voltage change as the battery discharges.
Important Voltage Warning:
The CP300 does not supply
a constant 24V output.
Only connect devices designed to tolerate
the complete 20–29.7V DC operating range.
If your equipment requires a constant 24V
supply, use a properly rated constant-voltage
power solution instead.
Battery Discharge Capability and Barrel Connector Current Limit
The CP300 and BX2494B use the same underlying
battery design, which supports a maximum
continuous discharge current of
10A.
The battery also supports up to
15A burst discharge for a maximum
of 10 minutes, subject to battery
condition, temperature and operating limits.
However, these battery discharge specifications
should not be confused with the current
rating of the CP300's 5.5 × 2.5mm
barrel output connector.
CP300 Barrel Connector – Recommended Maximum 6A Continuous
For the CP300, we recommend limiting the
continuous current through the barrel
connector to 6A maximum,
provided the complete connector and cable
assembly is appropriately rated.
Electrical power depends on both output
voltage and current consumption.
| Battery Output Voltage |
Calculated Power at 6A |
| 20V × 6A | 120W |
| 25.2V × 6A | 151.2W |
| 29.7V × 6A | 178.2W |
These are illustrative electrical calculations,
not guaranteed continuous output power ratings.
Actual safe operating limits depend on the
connector, cable, mating connector, equipment
input and operating conditions.
Need More Than 6A Continuous Output?
For applications requiring higher continuous
current, we recommend the
BiXPower BX2494B battery,
which is supplied with bare-wire output
for connection to appropriately rated wiring
and connectors.
