Do you know why Li-ion Cell Chemistry is the ideal option for Mobility applications? And on the other hand, Li-ion Cell Chemistry is more complex because of its non-linear behavior. Without the proper electronics (BMS) Li-ion cells can degrade faster, catch fire, or may even become useless for any applications.
