Package Contents:

1. HL2454B Battery x1
2.300W AC Charger x 1
3. Power Cord for AC Charger: x 1
4. Battery power output cable x 1 ( 3 Ft. long)
5. Battery power extension cable x 1 ( 6 ft. long)
6. Starlink power connector x 1

Using the Battery:

To use this battery to power a Starlink Mini device, just plug power output cable one end to the battery 2nd output port, plug Starlink power connector on the another end of power output cable, then plug it to Starlink Mini power input port.

The power output cable is around 3 feet long. If it is too short to reach Starlink Mini, you can add the 6 feet power extension cable (enclosed with package) between the power output cable and Starlink power connector.

This battery output voltage range is 21V ~ 29.5V, which is compatible with Starlink Mini. When the battery is fully charged, its output voltage is 29.5V. The output voltage will drop gradually during the discharge process and the final cut off voltage is 21V:

Important Note: This battery can directly power Starlink Mini dishes only. You will need extra power converters to use this battery to power other starlink devices.

Warranty: One Year limited warranty. The one year limited warranty covers manufacturing and quality defects only. Please note that batteries wear out with use. The amount of charge a battery can hold gradually decreases due to usage and aging, which is normal, and this is not the issue covered by warranty.
