Large-format prismatic lithium-ion battery cell, model M32, rated
166Ah (min., 1/3C) / 620.8Wh (min.) per cell. This listing consolidates two previous
batches into a single lot of 33 cells (approx. 20.5kWh combined),
identified and specified against the manufacturer’s official M32 product
specification sheet (Spec. No. PBRI-M32-D06-02, Rev. B).
⚠ Chemistry correction: earlier listings for this cell were
labelled LiFePO4 (LFP) — this is incorrect. The M32’s voltage profile (3.74V
nominal, 4.35V maximum charge voltage, 2.1–2.8V minimum discharge
depending on temperature) does not match LFP chemistry (LFP cells are typically
~3.2V nominal / 3.65V max charge). Configure any BMS or charger for this
cell’s actual limits below — do not use standard LFP charge settings, as
undercharging to 3.65V will leave significant capacity unused, and any assumption
of LFP safety margins should not be relied upon.

| Equipment type | High-voltage lithium-ion prismatic battery cell (M32) — not LiFePO4 |
| Model number | M32 (Spec. No. PBRI-M32-D06-02, Rev. B) |
| Nominal voltage | 3.74V |
| Charge voltage | 4.35V max |
| Discharge cut-off voltage | 2.8V (35–55°C) / 2.5V (10–35°C) / 2.1V (-30–10°C) |
| Capacity | 166.0Ah min. (1/3C, 25°C) |
| Energy | 620.8Wh min. (1/3C, 25°C) |
| Standard charge/discharge current | 55.3A (1/3C) |
| Internal resistance | ≤0.3mΩ (25°C, AC 1kHz, 30% SOC) |
| Cycle life | 1800 cycles @ 25°C standard use (0.5C/1.0C, 2–97% DOD) retaining ≥80% capacity |
| Dimensions | 194.3mm (W) x 112.9/110.2mm (H) x 50.7mm (thickness) |
| Weight | 2465g ±35g per cell |
| Energy density | ≥251Wh/kg, ≥572Wh/L |
| Quantity available | 33 cells (~20.5kWh combined) |
| Condition | Overall very good to excellent. Blue prismatic aluminium casings, clean, no dents/swelling/corrosion. Some units show minor surface scuffing/oxidation on the terminal blocks but are structurally sound; cells appear new or lightly used. No serial numbers visible on the cells — identification is by physical measurement/comparison against the manufacturer datasheet, buyers are advised to test cells before integration. |
