Product Details
The GEB 38120HP 3.2V 8Ah 15C High-Power Cylindrical LiFePO4 Battery Cell (120A Continuous, 38×120mm) is an industrial heavy-duty Lithium Iron Phosphate (LiFePO4) cylindrical cell engineered specifically for extreme high-drain motive and starting duties. Delivering a verified 3.2V nominal operating voltage, 8Ah rated capacity (25.6Wh energy), and an aggressive 15C continuous discharge capability (120A continuous) with pulse ratings up to 20C–25C (160A–200A ≤ 5s). Built with heavy-gauge nickel-plated steel casing (Ø 38.0 ± 0.5 mm × H 120.0 ± 1.0 mm) weighing approximately 310g, it features integrated dual M6 threaded screw stud terminals for high-torque copper busbar fastening, eliminating spot-welding limitations and ensuring ultra-low contact resistance (≤ 3.0 mΩ).
Product Overview
The GEB 38120HP 3.2V 8Ah 15C High-Power Cylindrical LiFePO4 Battery Cell is widely deployed in automotive engine starter batteries, high-output car audio competition banks, electric motorcycles, marine thrusters, and pulsed-power energy storage systems. Thanks to the chemical stability of its olivine LiFePO4 crystal lattice, the cell provides intrinsic thermal runaway protection even during extreme mechanical or electrical stress. Delivering 3.2V nominal voltage, 8Ah (8,000mAh) rated capacity, calibrated dimensions of Ø 38.0 ± 0.5 mm × H 120.0 ± 1.0 mm (excluding studs), and a cell weight of Approx. 310.0g ± 5.0g, it supports more than 2,000 deep discharge cycles at 1C rates.

Integration & Operational Boundary Conditions
Busbar Interconnection & Torque Specs: Use solid stamped copper busbars (minimum 15mm width × 2mm thickness) rated for 150A continuous. Tighten M6 terminal nuts with calibrated torque between 4.0 N·m and 4.5 N·m to avoid terminal stud thread stripping while ensuring zero contact resistance.
Cell Spacing & Cooling: When assembling multi-cell 4S (12.8V) or 8S (25.6V) banks, use dedicated 38mm modular plastic interlocking brackets with a 2mm–3mm air gap between cells for optimal thermal convective airflow under continuous high-amperage discharges.
B2B Procurement & Certifications: Supplied with copper connection links, stainless steel nuts/washers, UN38.3 compliance dossier, and MSDS documentation.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB 38120HP 3.2V 8Ah 15C High-Power Cylindrical LiFePO4 Battery Cell (120A Continuous, 38×120mm), verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.2V / 8Ah 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.
