During 2021, there was a minor upgrade for the design of the terminal connectors for the TSWB cells:
There is visual change of the shape of the terminals. The terminals are now fully circular and do have the size of a hexagonal nut.
The main difference is the former red plastic circle around the terminal of the cell will be replaced by red and black rubber sleeves to distinguish the positive and negative terminals. The new cover for the terminals (white-plastic) will be provided according to the changes.
There is no change the electromechanical specifications of the cells. All parameters and performance of the cells remain the same.
You can see the updated photos of the new designs of the terminals at the GWL/Shop.
