BiXPower 300Wh High-Capacity Regulated 12V Lithium-Ion Battery Pack
The BiXPower BP300-12V is a powerful
300Wh (25Ah @ 12V) rechargeable lithium-ion battery pack
designed to provide a constant, regulated and stable 12V DC output.
Unlike many conventional 12V battery packs whose voltage changes as the battery
discharges, the BP300-12V uses an internal DC voltage regulation system to maintain
a stable 12V output for compatible equipment.
With its combination of high 300Wh capacity, regulated 12V output,
compact size and approximately 5 lb weight, the BP300-12V is an
excellent portable power source for many compatible 12V electronic,
communications, medical, testing and mobile applications.

Regulated Constant 12V Output
One of the most important features of the BP300-12V is its
regulated 12V DC output. The internal power electronics
regulate the battery voltage so the output remains stable at approximately
12V throughout normal battery operation.
This makes the BP300-12V particularly useful for compatible electronics
that require a more stable 12V supply rather than the changing voltage
normally produced directly by a conventional battery.
Output: Regulated 12V DC
Maximum Output Current: 7A
Battery Capacity: 300Wh / 25Ah @ 12V
High 300Wh / 25Ah Capacity
The BP300-12V stores approximately 300 Watt-hours of energy,
equivalent to approximately 25Ah at 12V. This large capacity
provides significantly longer operating time than smaller portable battery packs.
Actual runtime depends on the connected device's power consumption,
operating conditions, battery condition and conversion efficiency.
As a general estimate, divide the battery's usable energy by the device's
average power consumption to estimate operating time.
Example: A device averaging 30 watts may theoretically
operate for approximately 10 hours from 300Wh of stored energy before
accounting for conversion losses and other operating factors.
Actual runtime will vary.
High Capacity in a Compact, Portable Design
Despite its substantial 300Wh capacity, the BP300-12V measures only
approximately 268 × 150 × 56 mm (10.6 × 6 × 2.2 inches)
and weighs approximately 2.2 kg (5 lb).
Its relatively slim enclosure makes the battery easier to transport,
integrate into equipment, or install in space-limited applications.
A Versatile Portable 12V DC Power Source
The combination of high capacity and regulated output makes the BP300-12V
suitable for many compatible 12V applications, including:
- Portable 12V electronic equipment
- Compatible medical and respiratory equipment
- Communications and field equipment
- Testing and measurement equipment
- Mobile electronics
- Portable monitoring equipment
- Emergency and backup DC power
- Remote-location equipment
- Camping and outdoor electronics
Always verify your equipment's required voltage, current, connector
polarity and startup/surge-current requirements before connecting it to the battery.
Important Notice for LED Lighting Applications
The BP300-12V is not recommended for many LED lighting applications.
Some LED lights can produce a very large startup or connection surge current,
sometimes many times higher than their normal operating current.
Repeated high-current surges can place excessive stress on the BP300-12V's
internal DC-to-DC voltage regulator. If your application has a large startup
or surge current, please select a battery specifically designed to support
that load or contact BiXPower before ordering.
AC Charger Included
The BP300-12V package includes an AC battery charger that accepts
approximately 100V–240V AC input, making it convenient for
use with common AC power sources.
A fully discharged battery typically requires approximately
5 hours to recharge under normal conditions.
Optional Solar Charging
For remote, outdoor and off-grid applications, the BP300-12V can also be
charged using a compatible BiXPower solar charging solution.
This can provide additional flexibility when normal AC power is unavailable.
Solar panel is optional and is not included in the standard BP300-12V package.
Mountable Battery Holder
The bottom of the battery holder includes
four mounting points, making it easier to secure the
BP300-12V to a desk, platform or other suitable surface when a more
permanent installation is required.
Flexible DC Output Connector System
The BP300-12V output cable terminates in a
5.5 × 2.5mm male DC barrel connector.
For equipment requiring another connector size, compatible BiXPower
C-series connector tips can be fitted over the standard output connector.
Before connecting your equipment:
Confirm that the device accepts 12V DC input, requires no more than the
battery's supported current, and uses the correct connector size and polarity.
Built-In Battery Protection
The BP300-12V incorporates battery management and protection functions
designed to help protect the lithium-ion cells and connected battery system.
- Cell balancing
- Over-charge protection
- Over-discharge protection
- Over-current protection
- Temperature protection
- Secondary protection

Why Choose the BiXPower BP300-12V?
Many rechargeable "12V" batteries do not actually maintain 12 volts
throughout their discharge cycle. Their output voltage gradually changes
as the battery is used.
The BP300-12V is specifically designed to provide regulated,
stable 12V DC power while also offering a substantial
300Wh / 25Ah capacity. This combination makes it a
practical choice for compatible equipment that benefits from both
long operating time and a stable DC power source.
Important:
Always verify your device's input voltage, maximum power/current requirement,
connector size, polarity and startup/surge-current requirement before use.
Do not use the battery with equipment whose requirements exceed the
BP300-12V specifications. High startup-current loads, including certain
LED lighting systems, may not be suitable for this battery.
