SOC monitor

Grading System

Cells purchased from manufacturers come in different batches, each with varying resistance and capacity. Strict sampling tests are conducted to verify capacity and performance. Approved cells are then stored for future use.
48V 500Ah display

Workshop

Covering over 6,000 square meters, the production lines are equipped with clear SOPs , emergency fire exits, and contingency plans. All equipment undergoes annual precision calibration, with detailed records maintained.

Sample Workshop

The semi-automated sample production workshop allows rapid customization through quick prototype assembly, preliminary thermal simulation, and thermal runaway testing, ensuring visible, quality-controlled outcomes.
Automatic Welding Machine

Laser Welding

Before mass production, welding diagrams are prepared in advance. Cells and copper bars are accurately arranged and then placed into the automated laser welding machines.
capacity test

Aging Room

After production, a comprehensive charge and discharge test is performed, recording capacity, charge/discharge rates, and temperature data for future traceability.
12V 100Ah series testing

SOC Calibration

Before shipment, all battery packs of the same batch are voltage-tested against their discharge curves to ensure uniformity at 55% SOC, preventing excessive discharge during sea transport.
48V ESS production line

Finished Goods

Finished products, after passing aging tests and SOC calibration, are placed in the warehouse for shipping. Products not shipped within a month are re-inspected before being restocked.
205ah cell

Cell Warehouse

Cells are sourced from brands like CATL, BYD, EVE, Gotion, and Samsung. Each cell receives a unique identifier and is managed through RFID once stored.

  • Q: How can I quickly find the battery I need?

    A: You can search by different product lines or by application scenarios.

  • Q: Do you only sell batteries?

    A: Besides batteries, we also provide BMS, battery enclosures, chargers, solar panels, and other related products.

  • Q: What is your delivery time?

    A: Standard products are produced within 15-20 days and shipped immediately via sea or air. Customized products are produced within 30-35 days. Sea shipping usually takes 28-35 days.

  • Q: What are your advantages?

    A: An extensive product line, fully traceable production processes, an average warranty of over 10 years, stable cell resources from CATL, BYD, Gotion, and EVE, and support for production process visualization.

  • Q: What payment terms do you support?

    A: For orders below $10,000 USD, we accept 100% prepayment via T/T. For larger orders, we require a 50% prepayment. Once production is complete, we provide videos and images or conduct live video inspections, and the balance is paid before shipping.

  • Q: How does your warranty work?

    A: Different product lines have different warranties. Electric motorcycle and high-rate power batteries generally have a 3-year warranty, 12V/24V energy storage battery packs come with a 5-7 year warranty, 48V home energy storage packs offer a 10-15 year warranty, and commercial energy storage packs generally have a 15-20 year warranty.

  • Q: What cell brands do you use?

    A: We use cells from leading domestic brands like CATL, BYD, EVE, and Gotion. If you have a specific cell brand in mind, we can accommodate your request.

  • Q: What BMS brands do you use?

    A: We have partner suppliers that provide custom Justlithium BMS for our standardized products. Our regular partners include Daly, Xiaoxiang, and JKBMS.

  • Q: Can I become your exclusive local distributor?
