Sinopoly SP-LFP60AHA-S2 cell with light plastic case
The LiFePO4 cells SP-LFP60AHA-S2 from Sinopoly is designed with a light plastic case. Unlike the hard plastic cases, this design allows to reduce some space and weight for the cell installations. However since the thickness of the plastic case is very small, these cells must be tight together firmly to prevent any change of the shape leading to a possible damage. Ideally these cells should be seperated by thin sheets of metal that increase the mechanical strength of whole pack and prevent from blowing of the cells.
