No disagreement with you there. Many would love to see a higher capacity battery back as the 2600mah and even some 2800mah cells have proven themselves as the real deal. In the flashlight world 10%-20% improvement in runtime is a big deal. Additionally, I'm sure there are some who would love to be able to purchase a PH45. For now, there are a few PH50's left floating around here and there so most of the enthusiasts have sought those. They'll eventually be gone though and it will be sad to see the end of the 40+ watt Polarions.
