Our Quality & Safety Approach

01

Cell-Level Inspection

We verify cell capacity, internal resistance, voltage consistency, and cycle life data against manufacturer specifications.

02

Pack Assembly Audit

On-site inspection of spot welding, insulation, BMS integration, and final assembly quality control processes.

03

Safety Testing Verification

Review of overcharge, short circuit, drop, and thermal shock test results. We ensure no batch ships without proper testing.

04

Shipping Compliance

Proper UN38.3 documentation, DG classification, and packaging compliance for safe international transport of lithium batteries.
