During TMC’s 2025 Annual Meeting & Transportation Technology Exhibition, Dragonfly Energy unveiled the new Battle Born DualFlow Power Pack. This lithium power system is designed to eliminate idle time and alleviate strain on starter batteries by providing dedicated power for hotel loads in long-haul trucks. Engineered for universal compatibility, the DualFlow Power Pack installs inside the sleeper cab under the bunk without modifications to existing systems.

When the truck is parked, the DualFlow Power Pack powers auxiliary loads by removing cycles from the starter batteries and extending the lifespan while reducing unnecessary engine starts. Once the truck is back in motion, it recharges using Wakespeed Charge Control Technology, using available energy without additional fuel consumption. Designed for heavy-duty trucking fleets and owner-operators with sleeper cabs, it is well-suited for fleets that do not use auxiliary air conditioners.

"As the long-haul segment looks for practical ways to incorporate electric power, we see the DualFlow Power Pack as a form of hybrid electrification that delivers real savings and efficiency that just makes good business sense," Wade Seaburg, CCO for Dragonfly Energy, said. "Built for the hardworking men and women who keep America moving, we believe it provides a reliable and affordable way to keep trucks powered and running efficiently. Fleets need practical, cost-effective solutions today, not just future promises. We believe this system helps them cut fuel costs, extend battery life, and reduce emissions without overhauling their existing infrastructure—making life on the road easier while driving real sustainability."

The Battle Born DualFlow Power Pack offers the following benefits:

  • Eliminates idling: Provides reliable power throughout the mandatory 10-hour rest period, eliminating the need for idling during rest periods and saving an average of four gallons of fuel daily.
  • Extends battery life: Protects starter batteries by minimizing deep discharges and idle strain, reducing the risk of premature failures and costly replacements.
  • Easy installation: Installs in under an hour with no physical modifications, making it a quick and hassle-free upgrade for any fleet or owner-operator.
  • Versatile design: Engineered to be universally compatible with most sleeper cab models and can  be mounted in any orientation—typically under the bunk inside the cab—to reduce vibration and shield it from road debris and wear.
  • Safe and reliable: Built with LiFePO4 battery chemistry and an advanced battery management system for industry-leading safety, performance, and dependability.
  • Built to last: Engineered for the demands of long-haul trucking and backed by a 10-year warranty, ensuring lasting durability and reliability on the road.

The Battle Born DualFlow Power Pack joins Dragonfly Energy’s portfolio of sustainable power solutions for the medium- and heavy-duty trucking industry. The solution is available for purchase.
