AI-Powered supplier vetting

SummaryChangsha Deligreen Power Co., Ltd. is a China-based trading company established in 2017, with 12 employees and a valid import/export license. It offers battery chargers, EV charging products, cables, and battery-monitoring products, and reports broad export-market coverage. The supplier states annual production of 10,000,000 active battery balancers and order fulfillment within 15 workdays in both peak and off-peak periods. However, it has no supplier-management-system certification, no new products launched in the past year, no ODM, major-brand OEM, or SDK capability, and only minor customization capability. Service governance is weakly documented: complaint handling and corrective/preventive-action procedures have no written procedures or records. It has an overseas warehouse but no overseas showroom, agents or branches, or offline trade-show participation. Customer feedback is self-reported as 99.5% positive, but no customer cases are provided.

CertificationsThe supplier’s certification of management systems is explicitly recorded as NIL. No management-system certification is evidenced in the provided information.

After-Sales capabilityThe supplier claims fast and reliable after-sales service and 99.5% positive customer feedback, and it has an overseas warehouse. However, it reports no written procedures or records for complaint handling or corrective and preventive actions, with no overseas agents or branches, so formal service capability is inadequately controlled.

R&D capabilityThe supplier reports two years of total R&D-engineer experience, but no new products were launched during the past year. It also states no R&D product-information progress, no ODM service, no major-brand OEM capability, and no available SDK, indicating limited documented innovation capability.

Production capacityThe supplier reports 10,000,000 pieces of annual active battery-balancer output, order fulfillment within 15 workdays in both peak and off-peak seasons, and six quality-control staff, while operating with 12 employees overall. These figures support stated production and delivery capacity, although its trading-company classification means manufacturing arrangements are not fully clarified.

Product Q&A

Q:Which current of the PCB should I choose?

It depends on your motor power or controller current limit. Below 350W choose 16A, below 500W choose 18A, below 800W choose 35A, below 1KW choose 60A. If unsure, please contact us.

Q:Can I use a bigger size of PCB than required?

Yes, choosing a higher spec (e.g., 80A instead of 60A) is OK and allows higher current, though it costs more. You cannot choose a lower spec than required.

Q:What kind of charger should I choose?

You must use a lithium battery charger. Do not use a lead acid battery charger as it might damage the MOS pipe of the PCB.

Q:If I have a PCB, do I need any balancers?

Yes, adding QNBBM balancers is perfect. While PCB prevents overcharge/discharge, added balancers improve lifespan and ensure full capacity usage as PCB balancing performance is often not satisfactory.

Q:How to judge if my PCB is broken or not?

Use a multi-meter to check if cell voltages are close. If the difference is 1V, performance is poor (short driving distance, early cutoff). If the PCB is broken, the battery cannot discharge even if voltage appears normal.
