航天锂电 / GBM 32700-6.0Ah

GBM (Hangtian Lithium) 32700-6.0Ah cylindrical LFP cell. Rated capacity 6.0Ah at 0.5C and 25±2°C. Diameter including wrapping 32.35±0.25mm, height 70.5±0.3mm, weight 141±5g. Charge limit 3.65V with 0.30A cutoff. Operating discharge cutoff: 2.5V at 20–45°C, 2.0V at −20–20°C. The separate standard discharge test specifies 2.0V at standard conditions, so a single unconditional lower voltage is not cataloged. Maximum continuous discharge 12A at 15–45°C, explicitly not for long cycle life; pulse 18A for 5s. Cycle life ≥2000 cycles: 0.5C CC/CV charge to 3.65V (<0.05C cutoff), 30min rest, 0.5C discharge to 2.5V, 30min rest, capacity retention ≥80% under standard 25±2°C test conditions. Revision A3 dated 2022-09-29.
