Big D Construction Field Study

A construction site operating a 25kW diesel generator was previously running the unit 24 hours per day, six days per week, consuming approximately 2.6 gallons of diesel per hour.

After deploying DAS Gen:

  • Over a 30-day operating period, the generator ran just 83.6 total hours

  • This eliminated 636+ generator run hours

  • Resulting in over $8,600 in diesel fuel savings in just one month

  • After accounting for DAS Gen’s monthly service cost, the site achieved more than $6,000 in net savings in that same period

As job demands increased to double and triple shifts, fuel savings continued to grow—without any change to the monthly DAS Gen rate.

Field Testimonials

★★★★★

“For jobs running extended shifts, DAS Gen is a game changer. The reduction in diesel usage alone justifies the system.”

Built for the Modern Job Site

Consumer-grade batteries aren't built for the high-vibration environment of a construction site. Expion360 batteries feature a fiberglass-infused, military-grade ABS case with reinforced internal ribs—eliminating the flimsy foam filler used by competitors. From heavy machinery vibrations to accidental impacts, our structural integrity ensures your power stays online when the deadline is tight.

All-Season Operational Readiness

Don’t let a cold snap stall your progress. While standard Lithium batteries fail to charge in the cold, our patent-pending Vertical Heat Conduction (VHC™) technology warms the battery core internally. This allows for safe, high-speed charging down to -4°F, ensuring your tools and equipment are ready for the morning shift, regardless of the overnight temperature.
