We’re excited and proud to announce the launch of our new ChargePak Portable Battery Testing System (BTS)! This new solution expands our Power Storage portfolio, and is designed for electrical utility, substation, and remote field applications; helping to identify and mitigate potential battery issues before costly system failures.
Today’s utility substation managers and operators are increasingly challenged to meet NERC PRC-005 and IEEE 450 standards, which require annual battery testing and thorough documentation. Traditional testing processes can be time-consuming and labor-intensive, reducing operational efficiency and increasing costs. Our ChargePak Portable BTS addresses these challenges by providing a fully integrated, portable system that simplifies setup, enhances accuracy, and streamlines compliance reporting.


Purpose-built from inception for ease of use, safety, and performance, our ChargePak can be trailer- or truck-mounted for travel; and includes everything needed in one simple, reliable solution! This reflects Trystar’s focus on practical innovation for modern utility and substation maintenance operations.
Engineered for performance and built for the future, our ChargePak combines a portable battery charger, load bank, and battery bank in one enclosure. The system’s intelligent cabling design eliminates the need to move batteries during testing; thereby simplifying maintenance and ensuring safer, more efficient operation. Its preassembled 125VDC 50AH battery delivers the instantaneous energy needed for medium-voltage breakers and solenoids, while supporting steady substation loads. The VRLA (valve-regulated lead-acid) pure lead plates enable the ChargePak to resist corrosion, offer high energy density, and maintain performance in harsh environments.
As Trystar continues to grow, we’re seeing an increased demand for reliable, future-ready power solutions … and we believe our new ChargePak reinforces our commitment to innovation, customer-focused engineering, and user-friendly solutions for our customers!
We hope you share our excitement about our new power storage solution! Please reach out to us to learn more!
