Why Lianli

What sets us apart

Four concrete reasons B2B buyers and OEMs choose Lianli over generic trading companies.

OE-number-match verified

Every EV battery SKU ships with the manufacturer's OE number stamped on the listing. Match by OE, get guaranteed fitment — no returns, no modification, no surprises.

Direct factory pricing

You buy at manufacturer cost. Chongqing-based production with in-house assembly eliminates the trading-company markup common in this industry — saving 20–40% on bulk orders.

Custom engineering

Voltage, capacity, BMS, connector, housing — we customize to your spec. Standardized platforms balanced with bespoke build-to-print for projects that don't fit a catalog part number.

Full QC trace documentation

Every shipped batch carries cell-level test data, capacity grading results, and compliance certificates — the paperwork your customs broker or downstream OEM audit demands.

Standards

Quality & compliance

Manufacturing and exported batteries meet the five core international certifications required for global B2B sale and lithium-battery transport.

IATF 16949

Automotive Quality

ISO 9001

Quality Mgmt

UN38.3

Transport Safety

EU Conformité

IEC 62133

Cell Safety Std

Quality assurance process

We follow ISO-aligned quality management from incoming cell grading through final pack testing. Each exported batch ships with capacity grading, internal resistance records, and BMS calibration logs.

Document trail supports downstream OEM audits, customs clearance, and warranty claims.

Compliance scope

Certifications cover the five scopes our B2B partners most commonly require: automotive-grade (IATF 16949), general quality (ISO 9001), dangerous-goods transport (UN38.3), EU market access (CE), and cell-level safety (IEC 62133).

Specific certification scope varies by product line and model — request the technical dossier for your application.
