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."
