AI-Powered supplier vetting

SummaryChangsha Deligreen Electronics/Changsha Deligreen Power Co., Ltd. is a China-based limited trading company established in 2017 with 12 employees and a valid import/export license. It offers battery and EV charging-related products, reports 90% export sales, and serves multiple international regions. Its stated annual output is 10,000,000 active battery balancers, with lead times within 15 working days in both peak and off-peak periods. The supplier has overseas warehouse capability and provides minor customization, supported by two R&D engineers. However, the evidence shows no new products launched in the past year, no ODM, branded OEM, or SDK capability, and no overseas agents, branches, showroom, or offline trade-show participation. Quality assurance, traceability, and formal service-management procedures are not documented; quality-control testing equipment is reported as zero. Customer satisfaction is claimed, but no specific customer cases are provided.

Supplier typeThe supplier is identified as a trading company and a limited company headquartered in Asia, with its operating entity in Hunan, China. It has 12 employees, is not part of a larger group, and holds a valid import/export license, indicating an independently operated trading business with export capability.

R&D capabilityThe supplier reports no new products launched in the past year, no ODM service, no branded OEM capability, and no SDK availability. It has two R&D engineers, but their stated responsibility is limited to minor customization, indicating limited documented innovation capability.

Production capacityThe supplier reports 10,000,000 pieces of annual active battery balancer output, lead times within 15 working days in both peak and off-peak seasons, and 90% export sales. These figures support operational production and export fulfillment capability, although the company is also classified as a trading company and has only 12 employees.

Customization capabilityThe supplier explicitly offers minor customization, and its two R&D engineers are assigned to provide minor customization. No evidence supports broader engineering, ODM, or SDK-based customization services.

Product Q&A

Q:Which current of the PCB should I choose?

Take 13S 48V pack as an example: Which PCB you should choose depends on the power of your motor or the current limitation of your controller. Below 350W, you can choose 16A. Below 500W, you can choose 18A, Below 800W, you can choose 35A, Below 1KW, you can choose 60A. Above 1200W, the same. If you are not sure, please contact us freely.

Q:Can I use bigger size of PCB than it should?

Suppose you need 60A PCB but you chose 80A, that is OK. 80A allows higher current. Nothing bad but a bit higher price. But if you choose 50A, sorry it is too small. So you can choose higher spec but can't choose lower one than it should have been.

Q:What kind of charger should I choose?

Lithium battery must be charged by lithium battery charger. You can't charge it with a lead acid battery charger. The lead acid battery charger might damage MOS pipe of the PCB.

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

Yes if you can add QNBBM balancers, that would be perfect. The Main function of PCB is to prevent batteries from over charged or over discharged, over heated etc. All the PCB /BMS in the world balance performance is not satisfactory. With balancers added, the batteries lifespan will be longer and the capacity will be fully used.

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

If you'd like to judge if the PCB is fine or not, please use a multi-meter and see if the voltage of each cell is close to each other or not. When the volt difference is 1V, the battery will have such performance: driving distance is short, cut off when started, charging time is very short. Under such situation, some battery is defective. When the PCB is broken, the battery can't be discharged when you measured the battery volt is normal.
