High-quality products tailored for wholesalers and distributors worldwide.
China Loong Energy Storage Co., Ltd. supplies battery cells, battery packs, energy storage systems, solar power equipment, industrial power solutions, and related products to international B2B customers. The following ordering process helps buyers confirm technical requirements, commercial terms, production details, packing, and delivery arrangements before an order proceeds.
Please send us an inquiry with your intended application, required quantity, destination country, and preferred delivery schedule. Depending on the product, useful technical information may include:
Reference photographs, drawings, datasheets, samples, or existing product specifications can help us evaluate the request accurately. If the required configuration is not yet finalized, our team can discuss suitable options based on the application.
Customization may include voltage and capacity configuration, cell type, enclosure dimensions, connectors, cables, battery management functions, communication settings, labels, color, logo, manuals, and packaging. Custom energy storage systems may also require confirmation of inverter matching, cabinet or container configuration, thermal management, monitoring, and system interfaces.
Quotations are prepared according to the confirmed specifications, order quantity, customization scope, packing requirements, destination, and applicable trade terms. Prices may be revised if technical requirements, quantities, materials, exchange conditions, freight costs, or other order details change before confirmation.
If development work, samples, tooling, engineering evaluation, or special testing is required, the related cost and schedule will be discussed separately. Any sample price or development charge is subject to written confirmation.
Before accepting a customized or application-specific order, China Loong Energy Storage Co., Ltd. may review the requested electrical, mechanical, communication, environmental, and safety parameters. Buyers should provide complete and accurate information about the intended application and operating conditions.
Samples or prototypes may be recommended for new designs, customized battery packs, system integration projects, or products that must connect with the buyer’s equipment. Sample availability, configuration, charges, and delivery timing depend on the product requirements. When samples are used, the buyer should complete compatibility and application testing before authorizing volume production.
An order is considered ready for processing after both parties have confirmed the applicable commercial and technical documents. These may include the quotation, proforma invoice, purchase order, specification sheet, drawing, bill of materials, label artwork, packaging details, and agreed trade terms.
Before confirmation, please verify the following information:
Changes requested after order confirmation may affect pricing, material availability, production progress, or delivery timing. Such changes will only take effect after written review and acceptance by both parties.
Payment arrangements are confirmed according to the product type, order value, customization level, production requirements, and transaction history. The accepted payment method, payment schedule, currency, beneficiary information, and banking charges will be stated in the relevant quotation or proforma invoice.
Production, material purchasing, or shipment will proceed after the applicable payment conditions have been met. Buyers should use only the bank account information shown on authorized commercial documents and should confirm any requested change to payment details directly with our sales team through a verified communication channel.
Any taxes, import duties, customs charges, bank fees, or destination expenses not included in the agreed price are the buyer’s responsibility unless otherwise stated in writing.
After order and payment conditions are confirmed, production is arranged according to the approved specifications and current material availability. Estimated lead time depends on the product model, quantity, customization, component supply, testing requirements, and production schedule. Any estimated date is subject to final confirmation for the specific order.
During production, we may communicate with the buyer regarding technical questions, artwork approval, component alternatives, or scheduling updates. For customized projects, photographs, drawings, parameter records, or other confirmation materials may be provided when appropriate.
Products are checked according to the confirmed order requirements and the applicable inspection process. Depending on the product, checks may cover appearance, dimensions, electrical parameters, functions, connections, communication, labels, accessories, and packing. If the buyer requires third-party inspection or a specific inspection procedure, the request should be submitted before order confirmation so that feasibility, timing, and costs can be reviewed.
Packing is selected according to product characteristics, order quantity, transportation method, and destination requirements. Battery cells, battery packs, rack-mounted systems, wall-mounted systems, stackable batteries, portable power stations, solar equipment, and containerized energy storage products may require different protective materials and handling arrangements.
Available transportation options may include express courier, air freight, sea freight, rail, or multimodal shipment, depending on the product, destination, shipment size, and applicable transport restrictions. Because lithium batteries, sodium-ion batteries, lead-acid batteries, and other energy storage products may be subject to special transport rules, the final shipping method must be reviewed for each shipment.
Freight charges, trade terms, insurance, customs documentation, and delivery responsibilities will be stated in the order documents or confirmed separately. Buyers are responsible for checking local import regulations, product access requirements, taxes, duties, and installation rules in the destination market unless otherwise agreed.
Shipping dates may be affected by carrier schedules, customs procedures, dangerous goods handling requirements, weather, port conditions, or other circumstances outside the manufacturer’s direct control. Tracking information or shipping documents will be provided when available under the agreed delivery arrangement.
The buyer should inspect the shipment promptly after receipt. Please check the outer packaging, product quantity, model, accessories, labels, and visible condition before installation or use. If the packaging appears damaged during delivery, the condition should be noted with the carrier and documented with clear photographs or video.
Any shortage, shipping damage, incorrect item, or specification discrepancy should be reported promptly with the order number, product model, serial or batch information where available, photographs, videos, and a clear description of the issue. The goods should be stored, handled, installed, charged, and operated according to the applicable instructions and safe operating practices.
For technical or product-related concerns, please contact China Loong Energy Storage Co., Ltd. with complete order and issue information. Our team will review the case and may request operating data, connection details, system logs, photographs, videos, measurements, or return inspection before proposing a solution.
After-sales handling depends on the confirmed order terms, product condition, installation method, operating environment, maintenance history, and investigation results. Products should not be opened, modified, repaired, connected incorrectly, or used outside the confirmed specifications without authorization, as this may affect troubleshooting and after-sales handling.
Possible resolutions may include technical guidance, replacement parts, repair evaluation, product replacement, or another mutually agreed arrangement, depending on the circumstances. Return shipments must receive written authorization and shipping instructions before dispatch.
The buyer is responsible for confirming that the selected product is suitable for the intended equipment, system, and local market. Installation and commissioning should be completed by qualified personnel where required, particularly for high-voltage battery systems, solar inverters, industrial power supplies, telecom power systems, EV charging energy storage systems, and containerized energy storage equipment.
The buyer should provide accurate application data, follow the supplied instructions, use compatible equipment, and observe applicable electrical, fire, storage, transportation, and environmental requirements. Requirements related to local approvals, grid connection, building codes, or end-product compliance should be communicated before ordering.
These general order terms provide an overview of the standard purchasing process. Product-specific quotations, proforma invoices, specifications, contracts, purchase orders, and other documents accepted by both parties will govern the corresponding transaction. If an order requires special commercial, technical, inspection, documentation, or delivery conditions, those conditions must be confirmed in writing before production or shipment.
