The Gree Altaimano LFP71173207/280Ah is a large-format 280 Ah prismatic LFP cell rated for
≥ 8,000 cycles and an exceptional −30 to +60 °C discharge range. Brand-new
2026 production makes it a strong fit for grid-scale BESS, commercial ESS, and heavy-duty
traction where long service life and cold-climate capability are required.
