Product Details
The GEB 60280 3.2V 50Ah Cylindrical LiFePO4 Battery Cell (Threaded Studs, 60×280mm) is a large-format industrial Lithium Iron Phosphate (LiFePO4) cylindrical cell delivering a verified 3.2V nominal operating voltage and 50Ah rated capacity (160Wh total energy). Engineered for commercial grid storage, marine propulsion, electric trucks, and telecom microgrids, this heavy-duty cell measures Ø 60.0 ± 0.5 mm × H 280.0 ± 1.0 mm and weighs approximately 1.85 kg. Featuring robust heavy-duty threaded stud terminals (M8/M12) at both ends, it enables rapid bolt-on copper busbar assembly with calibrated torque, ensuring low connection resistance (≤ 0.8 mΩ). It supports a continuous discharge rate of 1.0C–2.0C (50A–100A continuous) and peak burst output up to 3.0C (150A ≤ 10s) across ≥ 3,000 cycles.
Product Overview
The GEB 60280 3.2V 50Ah Cylindrical LiFePO4 Battery Cell is engineered to deliver high single-cell capacity combined with the structural rigidity and natural thermal dissipation of a cylindrical canister. Unlike prismatic cells that require heavy external mechanical compression fixtures to prevent cycle-induced swelling, the circular steel casing of the 60280 naturally resists internal expansion pressure. Delivering 3.2V nominal voltage, 50Ah (50,000mAh) rated capacity, calibrated dimensions of Ø 60.0 ± 0.5 mm × H 280.0 ± 1.0 mm, and a verified unit weight of Approx. 1.85 kg ± 0.05 kg, it delivers high reliability in industrial stationary storage and heavy transport electrification.

Integration & Operational Boundary Conditions
Busbar Bolting & Torque Guidelines: Utilize high-conductivity tin-plated copper busbars (≥ 25mm width × 3mm thickness) for 100A+ continuous configurations. Tighten terminal nuts with a calibrated torque wrench (8.0–10.0 N·m for M8, 12.0–14.0 N·m for M12). Never solder directly onto threaded studs.
Rack Mounting & Spacing: In high-voltage ESS racks (e.g., 48V 16S, 96V 30S, or 384V 120S), maintain a minimum 5mm cell spacing using flame-retardant ABS/PC brackets to promote natural vertical convective thermal dissipation.
B2B Logistics & Compliance: Each shipment includes busbars, insulating caps, UN38.3 vibration/shock test reports, and MSDS documentation for hazardous goods shipping.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB 60280 3.2V 50Ah Cylindrical LiFePO4 Battery Cell (Threaded Studs, 60×280mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.2V / 50Ah power curves.
- Commercial designs requiring high volumetric energy density and predictable discharge curves.
- Projects requiring batch consistency with automated barcode impedance sorting.
⚠ Operational Constraints & Limits:
- Do not discharge below minimum cutoff voltage or charge beyond 3.65V.
- Maintain operational surface temperature within -20°C to +60°C discharge (0°C to +45°C charge).
- Ensure connector polarity and pin assignment match system schematics prior to initial power-up.
