Product Details
The GEB 55380 3.2V 50Ah Cylindrical LiFePO4 Battery Cell (Threaded Studs, 55×380mm) is a heavy-duty large-format cylindrical Lithium Iron Phosphate cell engineered for utility energy storage, heavy commercial AGVs, and industrial marine power. Delivering a verified 3.2V nominal voltage and 50Ah rated capacity (160Wh energy content), this cell features an ultra-low internal resistance (≤ 1.2–1.8 mΩ), continuous discharge capability up to 2.0C (100A continuous), and 3.0C pulse discharge (150A ≤ 5s). With high-integrity laser-welded explosion-proof safety vents and M8/M10 copper-aluminum composite threaded studs, engineers can build robust, high-vibration-resistant modular battery packs. Ensure clearance for Ø 55mm holders and verified 3.65V charger cutoff before integration.
Product Overview
The GEB 55380 3.2V 50Ah Cylindrical LiFePO4 Battery Cell represents state-of-the-art large-scale cylindrical electrochemical manufacturing for high-reliability industrial power. Featuring 3.2V nominal voltage and 50Ah rated capacity (160Wh), the cell incorporates high-conductivity current collectors, an integrated pressure-relief valve, and heavy-duty steel shell packaging. With physical dimensions of Ø 55.0 ± 0.5 mm × H 380.0 ± 1.0 mm and a calibrated unit weight of Approx. 1.88kg ± 0.05kg, it eliminates the swelling issues common to pouch and prismatic cells under heavy compressive cycles. Engineered for commercial energy storage, AGVs, electric logistics vehicles, and telecom backup systems, the threaded terminal posts provide secure busbar bolting with low contact resistance.
