Where the 12.8 V / 25.6 V blocks fit

Standard-format LiFePO4 blocks from 384 Wh to 5,120 Wh, in 12.8 V and 25.6 V, with 4S2P to 8S1P cell arrangements. These are the building blocks used in vehicles, small cabins, telecom cabinets and 24 V pump systems — not a wall or floor system on their own.

The larger models carry a 100 A continuous discharge and a 10-second peak rating, which is what allows a 2–3 kW inverter to start a motor without the BMS tripping. Charge temperature is 0–50 °C; below freezing, charging must be inhibited, so a cold-store application needs a heated or temperature-managed enclosure.

384–5,120 Wh; 12.8 V (4S) or 25.6 V (8S); 100 A continuous on the larger models.
