SHENGNA Energy SIB 33140-7Ah
SHENGNA SIB 33140-7Ah cylindrical sodium-ion cell. Rated capacity 7 Ah; platform voltage 2.85 V; operating window 1.5-3.4 V. Diameter 33.2 +/-0.3 mm and height 140.0 +/-0.5 mm. Weight <=250 g is a maximum. Continuous discharge up to 5C (35 A) only at 15 <= T <30 C, with derating outside that interval. >=3000 cycles at 25 +/-2 C and 0.5C/0.5C to >=80% nominal capacity; source contains DOC/DOD terminology inconsistencies.
