Standards & Compliance
The C2PRO battery pack was evaluated against the primary standard and its amendment listed below. The product was confirmed to fulfil the requirements of the equivalent European harmonised standard as well.
| Standard | Title | Status |
|---|---|---|
| IEC 62133-2:2017+AMD1:2021 | Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for portable sealed secondary lithium cells, and for batteries made from them, for use in portable applications — Part 2: Lithium systems | Compliant |
| EN 62133-2:2017+AMD1:2021 | European harmonised equivalent of IEC 62133-2 (applicable to CE market access) | Compliant |
Test methodology covered both electrical abuse tests (continuous charge, over-charge, forced discharge, short-circuit) and mechanical/environmental stress tests (free fall, crush, thermal abuse, vibration, mechanical shock, and forced internal short-circuit design evaluation), ensuring a comprehensive safety assessment aligned with international portable battery requirements.
