AI-Powered supplier vetting

SummaryThe supplier demonstrates broad technical and service capabilities. It reports ODM, OEM for known brands, SDK availability, multiple customization modes, recent new-product development, 44 R&D engineers, and technical support extending through after-sales service. Production information cites advanced equipment, a complete production line, annual capacity of 6 million sheets, and products covering battery assemblies from 1 to 32 strings and protection systems up to 250A. Quality and management systems include 46 inspection staff, 40 test-equipment units, written procedures, ISO9001:2015 certification, and CE, RoHS, and FCC certifications. The supplier has overseas warehouse and agent/branch capabilities and has attended several offline trade shows. Financial records are indicated for multiple years, but the provided slices do not disclose substantive financial results. No specific customer names or documented customer cases are provided.

Supplier typeThe supplier presents itself as a manufacturer with R&D, ODM, OEM, and battery-system production capabilities. Its stated product scope includes battery assemblies from 1 to 32 strings and lithium battery protection management systems with working current up to 250A, while overseas warehouses and agents/branches support service delivery.

CertificationsThe supplier states that it holds an ISO9001:2015 certificate and has product certification capability for CE, RoHS, and FCC. These are explicit certifications or certification capabilities, although the slice does not provide certificate validity dates or detailed scopes.

After-Sales capabilityTechnology engineers are explicitly responsible for technical support during production and after-sales service. The supplier also reports overseas warehouse and overseas agent/branch capabilities, but it does not provide detailed after-sales response times, repair procedures, or service coverage by country.

R&D capabilityEvidence includes new products during the past year, 44 R&D engineers, responsibilities covering new-product development and technical support, ODM services, SDK availability, ERP integration, and ongoing digital-process construction. The slices support an established innovation and technical-development capability, although they do not quantify R&D investment or patent output.

Production capacityThe supplier states that it has advanced production equipment, a sound production line, annual capacity of 6 million sheets, and a complete product range. Quality resources include 46 inspection staff and 40 test-equipment units, while stated average lead times are within 15 workdays in both off-season and peak season; the capacity figure is not independently qualified by product or period.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full and flexible customization, and minor customization. ODM service, OEM service for known brands, and a product range spanning multiple battery-assembly configurations further support tailored production capability.

Product Q&A

Q:How to choose the suitable BMS?

Please provide: 1. Battery type (3.7V Li-ion or 3.2V LiFePo4); 2. Number of cells in series; 3. Peak power watt of load/motor and application scenario.

Q:How to activate the BMS?

Three methods: 1. Click activation switch on power board; 2. Press button on Bluetooth module; 3. Connect B-line to total negative pole during charging.

Q:What is the balance function?

When cell voltage reaches balance voltage (4.18V for Li-ion, 3.6V for LiFePo4), the BMS discharges that cell at 35mA to match others. If voltage difference is large, replace cells.

Q:What type of charger should I choose?

Use specific lithium chargers. LiFePo4 voltage = strings x 3.6V; Li-ion voltage = strings x 4.2V. Do not use lead-acid chargers as they may lack proper overcharge protection.

Q:Do you have Minimum Order Requirement (MOQ)?

No, we do not have an MOQ. We support various capacities, sizes, and welcome OEM/ODM requests.
