i posted in another subforum regarding a potential problem with my Sigelei 150watt mod not firing above certain wattages. Then i looked more into it possibly being a battery issue. The 2 Samsung 25R's that i bought were sold as a pair on Amazon. However, the 2 i bought differ from one another. One has 5 connection points, the other has 4. (See attached photos) Apparently, genuine Samsung's should only have 3 connection points? Does anyone know this to be true? Do these look fake? Or has anyone purchased the 25R's on Amazon? Thanks in advance!
