Model Identity
Check labels, model references, voltage/capacity information and ordered configuration.
Quality Control
Quality control is a documented process of checking identity, configuration, visible condition and applicable records—not a vague marketing label.
Control Points
Practical checks across the supply cycle
Visible Condition
Review packaging, terminals, connectors, enclosures and obvious transport damage.
Compatibility
Confirm the battery, charger, controller, wiring and intended vehicle match the approved configuration.
Record Keeping
Keep relevant quotation, invoice, serial, dealer and support records where the process requires them.
Receiving Review
A repeatable incoming-product process
Match Documents
Compare shipment and product references with the confirmed order records.
Inspect Packaging
Record visible impact, moisture, opening or other irregularities before distribution.
Check Labels
Confirm product model, serial, voltage and other applicable label information.
Escalate Variance
Separate and report mismatched or visibly damaged items for supplier review.
Release
Release only the accepted quantity and configuration to stock or customer allocation.
Customer Responsibility
Safe use continues after delivery
Customers and dealers should inspect the delivered product, follow the applicable manual and label, use only a compatible charger, avoid unauthorized modification and report abnormal heat, swelling, smoke, smell, sparks or damaged wiring immediately.
No website statement replaces product-specific instructions, the final quotation, warranty card, invoice or technical inspection.
- Keep labels and serial numbers readable
- Use the approved charger and wiring configuration
- Stop using visibly damaged or abnormal products
- Contact technical support before unauthorized repair

Frequently Asked Questions
Does quality control guarantee that a product can never fail?
No. Review and inspection reduce avoidable errors but cannot eliminate every manufacturing, transport, installation or operating risk.
Are all products tested in the same way?
No. The applicable checks depend on the product category, manufacturer information, transaction and available test process.
What should a customer do if the delivered model differs from the quotation?
Do not install or use it. Preserve the packaging and documents and contact STH immediately for review.
