Comparation listCylindrical LiFePO4 cellsPrismatic LiFePO4 cells
Constructioncan discharge with a high current, highest 25C in pulseWhen it drains in higher current, the temperature rises rapidly and leads to inner pressure increasing more and more, finally the cell gets swelled.
PerformanceWorked well after cycle for a long timeCapacity retension down when cycle a long time
Heat radiatingGood,our battery format will not exceed 55 degree C even if under high current drains.Not good
