Answer: The basic chemistry of all the cells is primarily the same. All LFP cells are using the same fundamental chemical process described as the LiFePO4 technology.  Though there may be some minor variations in the purity of the chemical materials, the functional performance of these cells is identical.

Some producers improve the performance of the LiFePO4 process by doping additional chemical elements. For example Winston Battery is using the rear earth mineral Yttrium. Check details about the „Enhanced-lithium-iron-technology“.
