AI-Powered supplier vetting

SummaryDanl New Energy Co., Limited is identified as a China-based limited trading company headquartered in Guangzhou, with stated manufacturing operations in Nansha. Its business focuses on smart battery chargers for lithium, lead-acid, and various electric-mobility applications. The supplier reports four production lines, 6–10 quality-control staff, a 97.24 m² manufacturing plant, and substantial export activity. It claims customization, ODM/OEM, two-year full warranty, and free replacement services. However, no certification information or specific customer cases is provided. The materials also contain differing establishment/export-history references, so corporate history should be verified before relying on those claims.

Supplier typeThe supplier is legally described as a limited company and classified as a trading company, while its materials also identify a factory/manufacturer operation at a Guangzhou address. Its business covers battery chargers and related electrical/electronics products, indicating a trading entity with stated manufacturing capability.

After-Sales capabilityDanl explicitly states that it provides after-service and claims a two-year full warranty policy with free replacement. These are clear stated service commitments, although no service process, response-time data, or verification evidence is provided.

R&D capabilityThe supplier states that it designs and manufactures switching-mode technology battery chargers and develops smart chargers for multiple battery chemistries and electric-mobility applications. This supports product-development capability, but no patents, R&D team information, or independently validated technology evidence is provided.

Production capacityThe supplier reports a 97.24 m² manufacturing plant, four production lines, and 6–10 quality-control staff. Its listed product range covers multiple voltage levels, battery chemistries, and vehicle types, providing explicit evidence of production scope, though actual capacity and output verification are limited.

Customization capabilityDanl explicitly states that it specializes in customizing smart battery chargers and provides ODM/OEM services and charging solutions for battery and EV factories or wholesalers. This directly supports customization capability across multiple battery and mobility applications.

Product Q&A

Q:What charger should I choose?

It depends on the battery type, capacity, application, and budget. Our engineers will recommend the most suitable charger or customize it based on your specific battery information.

Q:Can I charge several batteries in parallel?

Yes, the charger can maintain several batteries connected in parallel, treating them as one large battery. Ensure the total capacity is within the model's recommendation and use high-quality wiring to prevent high current flow between batteries.

Q:Can I leave the charger connected indefinitely?

For lead-acid batteries, the charger has a maintenance (floating) mode allowing it to stay connected for up to 24 hours. For lithium batteries without a BMS system, do not leave the charger unattended.

Q:What are the maximum charging voltages?

The max charging voltage is 58.8V for lead-acid batteries and 54.6V or 58.4V for lithium batteries, depending on the specific chemistry.

Q:Does the charger support different plug types?

Yes, the charger supports AU, Euro, and UK plug types, and custom plug types are available upon request.
