High-Capacity 322Wh Rechargeable Battery
The BX2499 battery stores
322 watt-hours (Wh)
of nominal energy.
This substantial energy capacity
makes it suitable for applications
requiring longer operating time
than typical small USB power banks.
Compact high-capacity BX2499 battery.
The battery measures approximately
175 × 110 × 75mm
(6.8 × 4.3 × 3 inches)
and weighs approximately
2kg (4.3 lb).
Its integrated handle makes
the battery convenient to carry
between workstations, field locations
and other portable applications.
Battery Controls and Connections
The battery includes:
- Integrated carrying handle
- Power On/Off switch
- LED battery charge indicators
- Dedicated charging input
- DC output connection
The battery's output is connected
to the included USB-C PD converter
through the appropriate DC output cable.
USB-C Power Delivery – Up to 100W
The included USB-C converter
accepts DC power from the
BX2499 battery and provides
USB-C Power Delivery output.
The converter supports
5V, 9V, 12V, 15V and 20V
output profiles.
A compatible USB-C PD device
communicates with the converter
to request an appropriate
supported voltage and current.
USB-C PD Output Profiles
| Output Voltage |
Compatible Applications |
| 5V | USB-C phones and small electronic devices |
| 9V | Compatible USB-C fast-charging devices |
| 12V | Compatible USB-C PD equipment |
| 15V | Compatible tablets and portable electronics |
| 20V | Compatible USB-C laptop computers |
The converter's maximum rated
USB-C output is
100W at 20V/5A.
Actual power delivery depends
on the connected device,
its supported USB-C PD profile
and operating conditions.
Important USB-C Compatibility Information:
A USB-C connector does not
automatically mean a device
supports USB-C Power Delivery charging.
The connected device must support
a compatible PD profile.
How USB-C Power Delivery Works
USB Power Delivery is a
communication protocol that
allows a compatible power source
and device to negotiate the
appropriate charging voltage
and current.
For example, a compatible
laptop may request 20V,
while a smaller USB-C device
may request 5V or 9V.
The converter automatically
responds to supported requests,
eliminating the need to manually
set the output voltage.
This flexibility allows one
battery system to support
multiple compatible USB-C
devices with different
power requirements.
Compact USB-C Converter Design
The converter measures approximately
78 × 36 × 24mm
and weighs approximately
180g (6.5 oz).
Its DC input accepts
10–32V DC
through a
5.5 × 2.5mm female
barrel connector.
The input cable is approximately
200mm (8 inches) long.
The attached USB-C output cable
is approximately
1000mm (40 inches) long.
The converter may become warm
during high-power operation.
Keep it in a ventilated area
and avoid covering it during use.
Understanding Battery Output Voltage
The BX2499 rechargeable battery
has a nominal voltage of
approximately 25V DC.
Its raw output voltage varies
from approximately
29.5V when fully charged
to approximately
20V near discharge cutoff.
During much of the discharge
cycle, battery voltage is
approximately 24–26V.
The USB-C PD converter accepts
the battery's changing DC voltage
and produces the negotiated
USB-C output voltage.
Important:
The battery's raw DC output
is not a regulated laptop
charging voltage.
Connect compatible USB-C
devices through the included
USB-C Power Delivery converter.
How to Charge the BX2499 Battery
The package includes
a compatible AC battery charger.
The charger accepts
100–240V AC input,
making it suitable for
standard household outlets
in many countries when used
with the appropriate plug.
- Turn off the battery and disconnect the load when practical.
- Connect the included charger to the battery's dedicated charging port.
- Plug the charger into a suitable AC outlet.
- Allow charging to complete according to the charger indicators.
- Disconnect the charger after charging is complete.
Charging Safety:
Use only the included
or BiXPower-approved
compatible charger.
The USB-C converter is
an output device and
must not be used to
charge the battery.
Connecting the Battery to the USB-C Converter
Connecting the system
is straightforward:
- Charge the BX2499 battery.
- Connect the battery's DC output cable to the USB-C converter's DC input.
- Connect the USB-C output cable to a compatible USB-C PD device.
- Turn on the battery's power switch.
- The converter and device negotiate an appropriate supported output voltage.
Confirm that the device
supports USB-C PD charging
and does not require
more than 100W input power.
Estimated Battery Runtime
The BX2499 battery stores
322Wh of nominal energy.
Actual runtime depends on
device power consumption,
converter efficiency,
battery condition and temperature.
The following examples use
an illustrative
85% usable-energy assumption,
equivalent to approximately
274Wh available to the device.
| Average Device Power |
Estimated Runtime* |
| 10W | 27.4 hours |
| 20W | 13.7 hours |
| 30W | 9.1 hours |
| 45W | 6.1 hours |
| 60W | 4.6 hours |
| 75W | 3.6 hours |
| 100W | 2.7 hours |
*Illustrative calculations use
322Wh × 85% = 273.7Wh.
These values are planning estimates,
not guaranteed operating times.
Actual runtime may vary significantly.
