Import 3.2v 50ah Prismatic Lifepo4 Rechargeable Battery — Buy in wholesale FOB from Supplier in China

This 3.2V 50Ah prismatic LiFePO4 cell from Vcell Power Co., Limited uses lithium iron phosphate cathode chemistry to deliver a nominal 3.2V with 50Ah capacity, suitable for energy storage systems, solar installations, and backup power applications. The cell charges to a 3.65V cutoff and discharges down to 2.5V, with standard charge current of 25A and maximum continuous discharge of 50A. A peak discharge capability of 150A for 1-3 seconds supports surge demands in inverter and motor-start scenarios. Internal resistance is specified at 2.0mΩ, and cycle life reaches 1500 cycles at 0.5C charge/discharge at 25°C. The prismatic aluminium case measures 148.3±0.5mm by 26.7±0.5mm by 129.8±0.5mm and weighs approximately 1.2kg, a form factor that permits efficient stacking and space utilisation in custom battery pack assembly.

LiFePO4 chemistry offers superior thermal stability compared to NMC or LCO alternatives, with the olivine structure resisting oxygen release at elevated temperatures. The prismatic format, as opposed to cylindrical or pouch construction, provides rigid mechanical integrity and predictable dimensional tolerances for automated pack assembly. The ±0.5mm dimensional tolerance on each axis is typical for prismatic cells in this capacity class, allowing consistent inter-cell spacing and compression pad design. Charge temperature range spans 0°C to 55°C, while discharge operates from -20°C to 65°C, though capacity fade accelerates below 0°C. The 1500-cycle rating assumes 0.5C rates; faster cycling or deeper discharges below 2.5V will reduce achievable cycle count. Standard industry practice for energy storage applications targets 80% state-of-health as the replacement threshold, which typically corresponds to 2000-3000 cycles under milder 0.3C conditions for cells of similar chemistry.

OEM manufacturers and system integrators source this cell for stationary storage, portable power stations, and solar battery builds where fire safety and cycle life outweigh gravimetric energy density priorities. The 50Ah capacity suits 48V systems (16S configuration, 51.2V nominal) common in residential energy storage, or 24V systems (8S) for marine and caravan applications. Buyers should confirm with Vcell Power Co., Limited whether cells are supplied with busbar interconnects, terminal hardware, or balancing leads, as these affect pack assembly labour and tooling requirements. The supplier's Harbour trust tier indicates a verified business entity, though the 0.00% response rate and zero recorded average response hours suggest communication delays; buyers should establish direct contact to confirm current stock, production lead times, and whether lot testing data or matching internal resistance batches are available.

Vcell Power Co., Limited operates from Room 2-308, Pengchengzhongjun Compass Innovation Industrial Park, Bao'an District, Shenzhen, 518100, China, placing it within the dense battery manufacturing and electronics supply chain corridor of southern China. The supplier holds a Harbour trust tier, indicating verified business registration, though the profile displays a 0.00% response rate and zero average response hours, which signals potential communication gaps that buyers should address early in sourcing discussions. The listing provides no information on factory certification, production capacity, R&D staff, years of operation, or client references, so claims about scale or experience cannot be independently verified from the available data.

The company's product focus centres on prismatic LiFePO4 cells for energy storage and backup power applications, with this 50Ah cell representing a mid-capacity offering suited to pack assembly rather than direct consumer sale. Buyers should note that the supplier profile does not list ISO 9001, IATF 16949, or IEC 62619 certification status, nor does it specify whether cells undergo 100% capacity testing, internal resistance sorting, or ageing screening before shipment. The absence of stated MOQ, price bands, or standard packaging configurations means these terms must be negotiated directly. Prospective purchasers should request factory audit access, test report samples, and confirmation of whether cells are shipped at 30% or 50% state of charge to comply with UN38.3 air freight regulations.
