Battery certifications
No certificate, number, issuing laboratory or register entry is published for it on their product page, their certifications page or their documentation library, so this is what the maker's own document states and not a confirmed listing.
- UL 2580Stated in manufacturer documentRELiON Battery — InSight GC2 48V — relionbattery.com/products/lithium/insight-gc2-48vView standard: UL 2580 →
RELiON print this as "UL2580", marked "(Cell)". The electric-vehicle battery standard, claimed here for the CELLS. RELiON's own 12 V pack in the same case claims UL1973 instead, which covers auxiliary power and sends traction batteries to this standard — so the difference between the two packs is not the box, it is what the machine does with it.
- UL 2271Stated in manufacturer documentRELiON Battery — InSight GC2 48V — relionbattery.com/products/lithium/insight-gc2-48vView standard: UL 2271 →
RELiON print this as "UL2271", marked "(Battery Pack)". THE STANDARD WHOSE OWN APPLICATION LIST NAMES GOLF CARS, claimed here for the assembled pack — which is the assignment the standard itself describes. It evaluates the cell, the pack and the battery management system, and not the vehicle or the installation.
- CEStated in manufacturer documentRELiON Battery — InSight GC2 48V — relionbattery.com/products/lithium/insight-gc2-48vView standard: CE →
RELiON print this as "CE", marked "(Battery Pack)". In most cases a manufacturer's own declaration rather than a third-party result, and it names no specific safety standard on its own. Which standards were applied to earn it is a separate claim and RELiON do not make it here.
- IEC 62133-2Stated in manufacturer documentRELiON Battery — InSight GC2 48V — relionbattery.com/products/lithium/insight-gc2-48vView standard: IEC 62133-2 →
RELiON print this as "IEC 62133-2 :2017", marked "(Lithium Batteries)". A PORTABLE-APPLICATIONS STANDARD ON A TRACTION PACK. IEC 62133-2 covers sealed lithium cells and the batteries built from them for use in portable equipment; a 15.6 kg battery bolted into a golf car's tray is not that. RELiON claim it on every InSight pack whatever the voltage or the application. Recorded as printed, with the mismatch named rather than resolved — the equivalent IEC standard for motive use including golf carts is 62619, and RELiON do not claim it.
Each standard listed is an independent claim about this specific product — one standard does not imply compliance with another.

Most recalls cover only certain model years, serials or build dates — view each notice to check it against your own unit.
- 2023-03-14United KingdomThe product has been identified as presenting a serious risk of fire as a manufacturing fault can lead to corrosion across the ribbon cable terminal where it mates with the Printed Circuit Board (PCB) for the Battery Management System.three serial number ranges, which the notice prints in full; it says the serial number is on the side of the battery.View recall →

The manufacturer has also stated where this pack does not fit: Never in series — the opposite of how the lead-acid string it replaces is wired. Check it against your own machine before buying.
