Battery Cell
The biggest advantage of prismatic cells is its thin profile, lightweight, and the effective use of space. Due to the rectangle shape of these cells, it can facilitate better layering and increase flexibility in the products. With big capacity, less cell assembled together makes monitoring on each battery cell instead of cell string become possible. Changing defective battery cell is feasible too when there is cell failure.
