从China供应商批发进口54.6v 20.4ah Lithium Ion Rechargeable Battery — FOB条款

This 54.6V 20.4Ah lithium ion rechargeable battery is a 13-series (13S) cell configuration delivering a nominal 54.6V with typical capacity of 20.4Ah and minimum guaranteed capacity of 20Ah. The pack presents an AC impedance resistance of 150mΩ and charges at a standard 4A current with a maximum charge current of 6A, reaching full charge in approximately four hours at the 54.6V maximum charge voltage. The discharge cut-off is set at 32.5V, with a maximum continuous discharge current of 30A, and the complete unit weighs approximately 3 kg.

Constructed with cylindrical or prismatic lithium ion cells in a hard-case pack format, this battery is designed for industrial duty cycles rather than consumer electronics. The operating temperature span of 0°C to +45°C during charge and -20°C to +60°C during discharge suits it to warehouse floors, outdoor logistics, and semi-controlled environments. Storage recommendations specify -20°C to +50°C for periods under one month, narrowing to -20°C to +40°C for up to three months, with 20°C being the ideal holding temperature at shipment state of charge.

Target buyers include OEMs of hotel service robots, automated guided vehicles, golf carts, patrol cars, electric tools, gas chromatographs, and uninterruptible power supply manufacturers. The pack is offered as a customisable lithium ion solution, so connector types, discharge protocols, and mechanical housings can be adapted to chassis requirements. Importers should confirm cell grade (A-grade vs. B-grade), cycle life rating, and whether battery management system firmware is locked or programmable before committing to volume orders.

Grace Battery Technology Development Co., Ltd is registered at Room 101B, Building 16, No. 481 Guiping Road, Xuhui District, Shanghai, 200000, China. The supplier carries a Harbor trust tier, which indicates a baseline verification level on the platform. The response rate is currently showing as 0.00 percent with an average response time of zero hours, so buyers should treat initial contact as untested and follow up proactively.

The listing presents itself as a custom battery pack specialist targeting industrial and e-mobility OEMs rather than retail consumers. No audited factory size, annual revenue, R&D headcount, or specific certification numbers are disclosed in the profile. The supplier's value proposition rests on configurable voltage, capacity, and connector options for robotics, electric vehicles, and backup power applications. Buyers should request direct evidence of ISO 9001, UN38.3 transport certification, and cell-level UL or IEC testing before finalising contracts.
