Product Details
The GEB IFR18650 3.2V 1500mAh High-Rate Cylindrical LiFePO4 Battery Cell is an industrial Grade-A Lithium Iron Phosphate cylindrical cell engineered for high-cycle and high-rate power applications. Delivering a verified 3.2V nominal operating voltage and 1,500mAh rated capacity (4.8Wh energy), it is rated for a sustained 10C continuous discharge (15.0A continuous) and pulse output up to 20C (30.0A ≤ 5s). Housed in an industry-standard 18650 steel canister (Ø 18.2 ± 0.2 mm × H 65.0 ± 0.3 mm) weighing approximately 42g, it combines superior thermal runaway resistance, over 2,000 cycles at 80% DoD, and flat voltage discharge characteristics. Important: this is an inherently safe 3.2V LiFePO4 cell requiring 3.65V charging cutoffs, and must not be used with 4.20V lithium-ion chargers.
Product Overview
The GEB IFR18650 3.2V 1500mAh High-Rate Cylindrical LiFePO4 Battery Cell is designed for high-stress duty cycles including professional cordless power tools, electric scooters, solar street lighting batteries, automated warehouse carts, and medical emergency equipment. Featuring high thermal decomposition thresholds (> 270°C) and low internal impedance (≤ 20 mΩ), the IFR18650 cell prevents thermal runaway under severe continuous operation. With standard dimensions of Ø 18.2 ± 0.2 mm × H 65.0 ± 0.3 mm and unit weight of Approx. 42.0g ± 1.0g, it serves as an ideal modular building block for long-life custom multi-cell battery packs.

Integration & Operational Boundary Conditions
Charger Cutoff Verification: Engineers must ensure charger electronics terminate charging at 3.65V per series cell. Never subject LiFePO4 cells to standard 4.2V lithium-ion charge voltages.
Modular Pack Assembly: For power tool and LEV pack assembly, pure nickel strips (≥ 0.15mm) and cell spacing brackets ensure proper heat sinking and structural integrity.
Factory Wholesale & Logistics: Supplied in wholesale master cartons with full UN38.3 test summaries, RoHS documentation, and MSDS sheets.
Equipment Compatibility & Engineering Fit Check
Before deploying GEB IFR18650 3.2V 1500mAh High-Rate Cylindrical LiFePO4 Battery Cell, verify these verified electrical and mechanical boundary requirements:
Operational Boundary Conditions
✔ Recommended Fit & Use Cases:
- Electronic devices and OEM packs matched with 3.2V / 1.5Ah 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.
