Applies in: US
A UL Certificate of Compliance, issued 2024-05-05, report reference MH66598-20240425, category BBCA 'Batteries for Use in Light Electric Vehicles', product description 'Battery Pack', models 'GC2-R-B4830, R-B5130A-GC2'. It is issued to EDG Sales International LLC, 164 Andrew Drive Stockbridge, GA 30281, not to a company named Epoch Batteries. It is linked from Epoch's GC2 product pages, and Epoch's own specification sheet names this pack GC2-R-B4830, which the certificate lists. The certificate states that it 'does not provide authorization to apply the UL Mark'. It covers the pack model only, not Epoch's complete kits. It has not been checked against UL's own Product iQ listing. Epoch's page also says 'UL 2271 Certified'.
CEManufacturer claimEpoch Batteries — 48V 30Ah GC2 Golf Cart Battery — epochbatteries.com/products/48v-30ah-gc2-lithium-golf-cart-batteryView standard: CE →
Printed by Epoch as 'Pack Certifications: UN38.3, CE'. CE is a marking, not a standard. Epoch name no directive, declaration of conformity or notified body for it.
UL 2580Manufacturer claimEpoch Batteries — 48V 30Ah GC2 Golf Cart Battery — epochbatteries.com/products/48v-30ah-gc2-lithium-golf-cart-batteryView standard: UL 2580 →
Printed by Epoch in the line 'Cell Certifications: UL1642, UL2580, UN38.3'. UL 2580 is a standard for batteries for use in electric vehicles, a pack-level standard, so its place in a line headed 'Cell Certifications' is unexplained. No certificate is published for it.

Each standard listed is an independent claim about this specific product — one standard does not imply compliance with another.

Epoch's own charger and Epoch's own pack. The charger page says it is "specifically programmed for 48V Lithium Iron Phosphate (LiFePO4) batteries", and this pack is one of Epoch's sixteen-cell LiFePO4 packs by its own specification. Epoch name a class rather than this SKU, so this row is exactly as specific as they were.
