Operating across 10 Asian countries with 600+ well-trained full-time employees , V-Trust delivers reliable product inspections , supplier evaluations , and lab testing services, guaranteeing that your Li-ion battery meet quality, performance, and safety requirements.
1. Ensuring Battery Safety & Compliance with Lab Testing
We arrange laboratory testing to confirm adherence to international safety and performance standards:
Environmental: RoHS, REACH, CA65
Abuse Testing: Short circuit, overcharge, nail penetration
Transportation: UN 38.3
Performance: IEC 61960 (capacity/cycle life)
2. Common Defects in Li-ion Battery Product Inspections
Safety Risks
Swelling/leaking cells
High resistance
Poor insulation (risk of short circuit)
Wrong Battery positive and negative poles marking
Performance Issues
Capacity deviation (>±5%)
High self-discharge rate
Voltage inconsistency across packs
Cycle Life Below Standard
Construction Defects
Spot-weld failures (anode/cathode)
Damaged separators
Poor sealing (moisture ingress)
Loose terminal connections
Certification Gaps
Blurry or Missing Labels/Markings (UL, IEC, UN38.3)
Our engineers evaluate battery samples for safety, capacity, cycle life, and certificates. We benchmark performance against your specs to identify optimal suppliers.
Production Monitoring
On-site oversight of electrode manufacturing, electrolyte filling, and sealing processes. We verify moisture control, spot weld integrity, and aging room protocols to prevent swelling/leakage defects at critical stages.
During Production Inspection
Once at least 10% of the Li-ion battery order is completed, ,our team performs a mid-production inspection to evaluate:
Cell stacking alignment
Tab welding strength
Initial capacity/IR consistency
This early-stage inspection helps minimize rework and avoids late-stage surprises.
Pre-Shipment Inspection
Before shipping, we perform a thorough final inspection of your electric bikes to confirm:
Safety: Hi-pot test, leakage current
Performance: Capacity, cycle life
Marking and labels: UN38.3 packaging, Class 9 labels
100% voltage/IR sorting
Container Loading Supervision
We verify pallet stacking, moisture barrier installation, and hazardous goods segregation. Container floor conditions and secure lashing are monitored to prevent damage or corrosion during transit.
