LiFePo4 IFR26650 Rechargeable Battery 3.2V 12A 4000mAh (NEW) The LiFePO₄ IFR26650 (4000 mAh) presents itself as a stout cylindrical cell engineered for dependable, long-life energy delivery. Its exterior sleeve is clean and factory-finished, with the standard IFR form factor that signals easy integration into multi-cell packs. Visually the cell reads as utilitarian and robust no unnecessary ornamentation, just a clear indication of manufacturer identity and basic ratings. Beneath the sleeve is a construction optimized for stable chemistry and mechanical integrity: electrode layers and separators packed to priorities long cycle life and safe thermal behavior. The cell’s proportions and terminal details reflect attention to manufacturing consistency so that each unit stacks, connects and cools predictably inside packs. The overall feel is one of engineered restraint designed to perform reliably rather than to impress. Functionally, the IFR26650 gives the impression of a workhorse: sized for high-capacity LiFePO₄ applications where safety, wide operating temperature range and cycle life matter. Markings are practical model, nominal voltage and capacity and packaging is industrial, aimed at bulk handling and safe transport. Overall, the cell communicates durability and suitability for repeated, demanding charge/discharge duty. Features: LiFePO₄ chemistry for stable thermal and cycle performance. High nominal capacity: 4000 mAh. Low max alternating internal resistance (≤ 23 mΩ). Wide operating temperature range for discharge (−20 °C to 60 °C).

From Micro Ohm's description

LiFePO4 IFR26650 Battery 3.2V 4000mAh (Single Cell) – High-Rate, Long-Life Overview The LiFePO4 IFR26650 3.2V 4000mAh cell is a cylindrical high-reliability battery for packs that need strong current delivery, long cycle life, and robust safety. Typical use cases include power tools, e-mobility sub-packs, solar storage buffers, LED lighting, UPS modules, and general DIY energy projects. The cell follows a standard 26650 envelope— Ø26.2 ± 0.2 mm × ≤ 65.2 mm , ≤ 91 g —and uses CC-CV charging to 3.65 ± 0.05 V , with standard 0.5C (2000 mA) charge and 0.02C (≈80 mA) termination. Rated 3.2 V nominal , 4000 mAh nominal (min 3900 mAh ), low AC impedance ( ≤ 23 mΩ @ 1 kHz ) and wide thermal window support demanding field work. Why this cell ✅ True high energy @ 3.2 V: 4000 mAh nominal , ≥ 3900 mAh minimum at 0.5C to 2.5 V. ⚡ Strong discharge capability: up to 3C (12 A) continuous in 5–45 °C , with defined limits at low/high extremes for longevity. 🧊 Wide operating range: charge 0–55 °C ; discharge −20–60 °C . 🔁 Long cycle life: ≥ 1500 cycles to 80% (0.5C charge/1C discharge). 🧲 Low internal resistance: ≤ 23 mΩ for excellent voltage hold and efficient high-rate service. 🛡️ Safety-tested chemistry: LiFePO4 with rigorous short-circuit, over-charge, thermal abuse (130 °C), extrusion & impact tests— no fire/explosion criteria. Key Features 🔋 4000 mAh class energy with stable 3.2 V platform for flatter discharge curves. ⚙️ 3C capability (up to 12 A ) in mid-range temps; 1C at high (45–60 °C); 0.5C at low (−20–5 °C). 🔌 Fast CC-CV charging to 3.65 V , with temp-dependent current limits for long life. 🧯 Robust safety suite (forced discharge, 12 V over-charge, short, heat 130 °C, squeeze 13 kN, heavy impact, vibration, seawater, low-pressure, temp cycle, nail) → no fire/explosion . 🧠 Excellent storage behavior & recovery after 28-day/60 °C conditions ( ≥ 92–95% capacity retention/recovery).

Low-temp/High-temp relative capacities (0.5C): −20 °C ≥ 40% , −10 °C ≥ 60% , 0 °C ≥ 70% , 60 °C ≥ 95% . Integration & Pack Design (Pro Tips) 🛡️ Use a BMS per series string: OVP ≤ 3.75–3.80 V , UVP ≥ 2.5 V , OCP/short, temp probes; add balancing for multi-cell packs. (Derived from charge/discharge windows and safety items in spec.) 🔩 Spot-weld nickel tabs—avoid direct soldering on cell terminals to protect seals. (Industry best practice.) 🌡️ Respect temperature-based charge limits ; pre-charge gently if cell < 3.0 V (≤ 0.2–0.5C depending on temp band). 📦 Storage: cool, dry, and partially charged; the spec shows strong capacity recovery after prolonged storage at room/high temp. Safety Summary (User-Facing) 🚫 Do not short, crush, pierce, reverse, or incinerate; keep away from water/heat. If electrolyte contacts skin/eyes, rinse with plenty of water and seek medical attention. Keep out of children’s reach. 🧪 The cell passes severe tests (forced discharge, 12 V over-charge, 130 °C heating, crush/impact/vibration, seawater immersion, low pressure, temperature cycling) with no fire/explosion requirement.
