Prototype success story
From first article packs to field-proven programs
One recent path started with a tight thermal envelope, aggressive duty cycle, and a customer team that could not afford guesswork. We paired laser-welded busing, disciplined validation, and small-batch contract assembly in Troy—then scaled documentation and build repeatability as programs matured. That same playbook supports heavy-equipment programs in the Caterpillar ecosystem and marine lithium platforms that have drawn editorial interest in Battery in Boat magazine.
Bench to pilot, without losing traceability
Cell selection, module strategy, and electrical layout stay linked to test reports and revision history so every pilot build can explain itself to engineering and compliance stakeholders.
Built for harsh vibration and long shifts
Mechanical strategy, weld quality, and thermal pathways are tuned for construction, mining, and ground-support environments where downtime is measured in lost revenue.
Publication-ready marine performance
Salt-air exposure, dockside charging, and weight targets get the same rigor we apply in the assembly facility—so stories in the trade press reflect measurable results, not marketing claims.
Success stories
from the field
A few snapshots of programs we're proud to talk about—industrial battery pack assemblies in the Caterpillar ecosystem, marine platforms that earned coverage in Battery in Boat magazine, and repeatable prototype-to-repeatable assembly programs supported in Troy.
Battery in Boat
Marine lithium programs engineered for salt-air exposure, weight targets, and dockside charging—work that editors followed because the performance data stood up to scrutiny on the water.

Prototype → fleet
The same Troy team that signs off on prototypes carries forward weld recipes, thermal models, and documentation—so pilot builds evolve into repeatable contract assembly without a handoff cliff.
