从China供应商批发进口54.6v 42.9ah Li-Ion Customized Battery Pack — FOB条款

This 54.6V 42.9Ah lithium ion battery pack is arranged in a 14-series (14S) configuration with NMC (nickel-manganese-cobalt) cathode chemistry, delivering higher energy density than LFP alternatives at the same voltage tier. The 42.9Ah capacity implies a total energy content of roughly 2.34 kWh, positioning it for service robots, autonomous mobile robots, and electric vehicles where extended runtime between charges is critical. The pack is marketed as a customised OEM/ODM solution with adaptable voltage, capacity, and connector specifications to suit specific chassis integrations.

The NMC cathode material offers a favourable惦记 nominal cell voltage of 3.6-3.7V, which aligns with the 14S arrangement yielding the 54.6V pack-level nominal. NMC chemistry typically provides 150-220 Wh/kg at the cell level, though realised pack-level energy density depends on the BMS, thermal management, and mechanical housing. The listing indicates that voltage, capacity, and connector can be customised, suggesting the supplier holds relationships with cell vendors and has in-house or partnered pack assembly capability rather than offering a fixed-SKU commodity product.

Buyers in robotics, automation, and material handling sectors are the primary audience, with specific mention of service robots and autonomous guided vehicles where the 42.9Ah capacity supports multi-shift operation. The pack is shipped from China with UN38.3 certification cited, though buyers should verify that certificates are current and lot-specific. As a customised product, the actual dimensions, weight, and terminal configuration will vary by order, so mechanical and electrical integration drawings should be finalised before production commitment.

Grace Battery Technology Development Co., Ltd maintains its registered address at Room 101B, Building 16, No. 481 Guiping Road, Xuhui District, Shanghai, 200000, China. The supplier holds a Harbor trust tier, representing a foundational verification status. The response metrics show 0.00 percent response rate and zero average response hours, so communication reliability has not yet been demonstrated to potential buyers.

The company positions itself as a provider of customised lithium ion battery solutions rather than a catalogue vendor, with emphasis on OEM and ODM engagement for robotics and e-mobility sectors. No specific factory area, production line count, annual throughput, or client references are disclosed. The profile does not list ISO 9001, IATF 16949, or other quality system certificates directly, so buyers should obtain and verify these independently before committing to volume orders.
