High-Capacity 322Wh Rechargeable Battery
At the heart of the CP300-12V system is the
BiXPower BX2494 rechargeable battery,
providing approximately 322 watt-hours (Wh)
of stored energy.
Unlike smaller portable battery packs, this battery
offers substantial energy capacity for applications
requiring longer operation between charges.
The battery uses a nominal voltage of approximately
25.2V and has a rated capacity of 12.8Ah.
The included DC converter transforms its variable
output voltage into stable 12V DC power.

Compact Design and Convenient Battery Controls
The battery measures approximately
10.6 x 6 x 2.2 inches
(268 x 150 x 56 mm) and weighs approximately
5 pounds (2.2 kg).
The integrated power switch, battery charge-level
indicators, and dedicated charging connection make
the system straightforward to operate.

Mounting Options
Four mounting holes on the bottom of the battery
allow the pack to be secured to a suitable surface
or mounting structure.
This is useful for equipment installations, workstations,
portable systems and other applications where the battery
should remain in a fixed position.

Stable Constant 12V DC Output
The battery's voltage changes as its charge level
decreases. Many 12V electronic devices, however,
require a more stable power supply.
The included high-efficiency DC-to-DC converter
solves this problem by converting the battery's
variable DC voltage into a
regulated constant 12V DC output.
Complete rechargeable battery and regulated 12V power system
Why regulated constant 12V power matters:
A stable output voltage helps compatible electronic
devices receive the correct operating voltage even
as the rechargeable battery gradually discharges.
High-Efficiency DC-to-DC Power Converter
The included converter is compact and lightweight,
measuring approximately
2.5 x 1.9 x 0.7 inches
and weighing only 2.54 oz (72 g).
It accepts a wide 10V–30V DC input range
and delivers a regulated 12V DC output,
rated up to 6A (approximately 72W).
With conversion efficiency of up to approximately
96% under suitable conditions,
the converter is designed to reduce wasted energy
and make efficient use of the battery's capacity.
Actual efficiency depends on operating conditions.
Compact converter designed for portable DC power applications
Converter Input Connection
The converter has a DC input jack for connecting
to the battery's output cable. Verify connector
compatibility and polarity before connecting
another power source.
12V Output Cable
The converter provides regulated 12V DC power through
its output cable. The cable terminates in a
5.5 x 2.5 mm male DC connector,
which can connect to compatible equipment.
Additional USB Power Output
The converter also includes a USB output port
for compatible USB-powered devices.
Supported USB output ratings include:
- 5V DC, up to 3A
- 9V DC, up to 2A
- 12V DC, up to 1.5A
Available voltage depends on the connected device
and supported charging protocol. The USB port
does not replace the main regulated 12V DC output.
How Long Can the CP300-12V Battery Last?
The battery stores approximately 322Wh of energy.
Operating time depends on the connected device's
power consumption, converter efficiency, battery
condition and operating environment.
The following estimates assume approximately
85% of the rated battery energy is delivered
to the connected equipment after losses and
other real-world factors.
Runtime calculation:
Estimated hours = 322Wh x 0.85 / device power in watts.
These estimates are provided for planning purposes
only. Actual operating time may be shorter or longer.
Battery Voltage and Discharge Characteristics
The BX2494 battery has a nominal voltage of
approximately 25.2V. Its output voltage varies
with the battery's state of charge.
When fully charged, the battery voltage may reach
approximately 29.5V. As the battery discharges,
its voltage gradually decreases until the
battery protection system disconnects the output
at approximately 20V.
The included converter maintains a regulated
12V output throughout its supported input range.

How to Use the CP300-12V Battery
Step 1 — Charge the Battery
Connect the included AC battery charger to the
battery's charging port, then connect the charger
to a suitable 100–240V AC power outlet.
Charge the battery according to the charger's
instructions before its first use.
Dedicated battery charging input
Step 2 — Connect the DC Power Converter
Connect the battery output cable to the input
of the included 12V DC power converter.
Connect the converter's 12V output cable to

Frequently Asked Questions
Is the CP300-12V output voltage always 12V?
The battery itself has a variable voltage of
approximately 20V–29.5V. The included converter
provides regulated 12V DC output while operating
within its specified input and load limits.
Can I use the battery with a device requiring 12V and 5A?
Yes, provided the device is compatible with
the connector and polarity. A 12V, 5A device
requires approximately 60W, which is within
the converter's rated 72W output.
How long can the battery run a 30W device?
A 30W device may operate for approximately
9 hours based on an illustrative 85% usable-energy
assumption. Actual runtime depends on operating
conditions and device consumption.
Can I recharge the battery from a wall outlet?
Yes. The package includes an AC charger compatible
with 100–240V AC input.
Can I use the battery for a CPAP machine?
Only if the machine's voltage, connector, polarity
and power requirements are compatible with the
system. Some CPAP machines require 19V or 24V
rather than 12V, and may require a specialized
power cable or converter.
Can I take the CP300-12V on an airplane?
The battery has a capacity of 322Wh, exceeding
the usual 160Wh maximum permitted for spare
lithium-ion batteries on passenger aircraft.
Do not assume it is approved for passenger
airline transport.
