Battery certifications
No certificate number, issuing laboratory or register entry is published, so this is what the maker's own page states and not a confirmed listing.
- UL 2271Stated in manufacturer documentU.S. Battery — US 48V GC2 — usbattery.com/us-48v-gc2View standard: UL 2271 →
U.S. Battery print this as "UL2271 (Pack)" on the product page. The light-electric-vehicle pack standard whose own application list names golf cars, claimed for the assembled pack — the assignment the standard itself describes.
- UL 2580Stated in manufacturer documentU.S. Battery — US 48V GC2 — usbattery.com/us-48v-gc2View standard: UL 2580 →
U.S. Battery print this as "UL2580 (Cells)" on the product page. Claimed for the cells, matching the pattern RELiON's InSight packs also follow — a cell standard and a pack standard are not interchangeable claims.
- UN 38.3Stated in manufacturer documentU.S. Battery — US 48V GC2 — usbattery.com/us-48v-gc2View standard: UN 38.3 →
U.S. Battery print this as "UN 38.3" on the product page. The UN transport-testing standard for lithium cells and batteries, printed with no scope marker distinguishing cell from pack.
Each standard listed is an independent claim about this specific product — one standard does not imply compliance with another.
