Dragonfly Energy expands DualFlow Power Pack line to support more commercial truck electrical systems
Key takeaways
- Dragonfly’s new 24V DualFlow Power Pack powers sleeper cab hotel loads while protecting starter batteries and reducing engine idling.
- The system adds 3.45 kWh, integrates with truck electrical systems, and works in cold weather to maintain cab comfort and uptime.
- Compact design fits various truck platforms, supports 10-hour rest periods, and lowers fuel use and maintenance costs for fleets.
Dragonfly Energy recently debuted at TMC 2026 the availability of a 24-volt configuration of its DualFlow Power Pack, extending the idle-reduction solution to a broader range of commercial truck electrical systems.
The company, which develops energy storage and battery solutions and produces Battle Born Batteries, designed the DualFlow Power Pack to power sleeper cab hotel loads during driver rest periods while preventing deep discharge of chassis starter batteries.
The expanded system integrates directly with a truck’s electrical architecture and recharges via the alternator while the engine is running, allowing fleets to maintain cab power without extended idling. The 24-volt configuration provides an additional 3.45 kWh of stored energy, features an integrated battery management system for safety and performance protection, and includes internal heating technology for cold-weather operation.
The compact under-bunk design and flexible mounting options enable installation across a variety of truck platforms while preserving sleeper cab space. The system supports the federally mandated 10-hour rest period, powering hotel loads without running the engine, reducing fuel use, and protecting starter batteries from deep discharge cycles that can cause premature failure.
“Fleets today operate a wide range of truck platforms, leading to significant variations in electrical system requirements and chassis voltages. However, a common denominator is the increasing demand for more power inside the sleeper cab,” said Wade Seaburg, CCO of Dragonfly Energy. “By expanding the DualFlow Power Pack line to support both 12-volt and 24-volt configurations, we believe we’re giving fleets a consistent idle-reduction solution across more vehicles while protecting starter batteries and minimizing downtime.”
