36V 300Wh High-Capacity Lithium-Ion Battery for Starlink Mini
Lightweight, direct DC portable power for extended Starlink Mini operation
The BiXPower BX3694G-M521 is a high-capacity
36V 300Wh rechargeable lithium-ion battery designed to
provide convenient portable power for Starlink Mini.
Unlike a bulky AC power station, this battery provides direct DC power
to Starlink Mini without requiring a DC-to-AC inverter. This creates a
compact and efficient portable power solution for camping, RV travel,
remote work, field operations, emergency communications, and off-grid use.
Key Features
✓ 300Wh High Capacity:
Provides substantial stored energy for extended Starlink Mini operation.
✓ Direct DC Power:
Powers Starlink Mini directly from the battery without requiring a bulky
DC-to-AC inverter or portable AC power station.
✓ Lightweight for Its Capacity:
The battery weighs approximately 4.2 lb (1.8 kg) without
the mounting holder.
✓ Premium Lithium-Ion Cells:
Built with premium-brand lithium-ion cells for dependable performance.
✓ High-Power Output:
Supports up to 10A continuous discharge and up to
15A burst discharge for up to 10 minutes.
✓ Weather-Resistant Housing:
Designed for outdoor use with a durable enclosure that helps protect the
battery from normal outdoor exposure.
✓ Mounting Capability:
Four mounting points on the bottom allow the battery to be secured to
the included holder or another suitable mounting surface.
✓ AC Charger Included:
Recharge the battery conveniently from AC wall power.
Extended Starlink Mini Runtime
With a large 300Wh energy capacity, the BX3694G-M521 can
provide many hours of portable Starlink Mini operation. For example, at an
average power consumption of approximately 20W–30W,
the theoretical battery-energy calculation is approximately
10–15 hours before accounting for conversion losses,
battery reserve, operating conditions, and variations in Starlink power consumption.
Actual runtime varies with Starlink Mini power consumption, network activity,
weather, temperature, battery condition, and other operating conditions.
Designed for Starlink Mini
This battery package is configured specifically for
Starlink Mini. It is not intended as a direct power solution
for Standard Gen 1, Standard Gen 2, Standard Gen 3, or Flat High Performance
Starlink systems.
Direct DC Power — No AC Inverter Required
The BX3694G-M521 provides a nominal 36V DC output with an
operating voltage range of approximately 30V–42V.
The integrated power cable allows the battery to connect directly to
Starlink Mini, eliminating the need to first convert battery power to
110V AC.
This direct-DC approach keeps the system simple and portable while avoiding
the additional size and conversion losses associated with an AC inverter.
Built for Portable & Outdoor Use
The durable battery enclosure is designed for portable outdoor applications.
Its compact form factor makes it practical for camping, field work,
emergency communications, remote job sites, RV travel, and other situations
where conventional AC power may not be readily available.
Important: Weather-resistant does not mean waterproof.
Do not immerse the battery in water or expose it to conditions beyond
its intended outdoor use. Keep the charging connection and electrical
connections protected from water.
Compact 300Wh Power
Despite its large 300Wh capacity, the battery maintains a compact profile.
Approximate dimensions are 265 × 148 × 56mm
(10.6 × 5.8 × 2.2 inches).
The battery itself weighs approximately 1.8 kg (4.2 lb).
With the battery holder installed, total weight is approximately
2.3 kg (5.3 lb).
Four Bottom Mounting Points
Four mounting points are built into the bottom of the battery housing.
These mounting points allow the battery to be secured to the battery holder
or an appropriate mounting surface for a cleaner and more secure installation.
