Product Details

Direct Answer / Engineering Summary

The GEB INR18650 3.7V 3000mAh Cylindrical Lithium-ion Battery Cell (High-Cycle Model) is a premium high-energy cylindrical cell engineered for commercial electric mobility, light electric vehicles, and stationary energy storage modules. Featuring a 3.7V nominal operating voltage and 3,000mAh rated capacity (11.10Wh energy content), this cell incorporates high-stability nickel-manganese chemistry that ensures low internal AC resistance (≤ 25–35 mΩ) and sustained 3.0C continuous discharge capability (9.0A continuous) with 5.0C pulse burst capability (15.0A ≤ 5s). Built with an integrated safety vent (CID/PTC) and heavy-duty steel shell packaging, it provides superior cycle life and thermal endurance. Before pack assembly, confirm pure nickel welding tab specifications, multi-cell grading criteria (ΔV ≤ 3mV, ΔR ≤ 1.5mΩ), and 4.20V charging parameters.
