Wow, these guys sell everything!!!! I am going to give their batteries a shot. I am going to purchase individual cells and build them up into packs. The numbers look standard on their batteries, so I do not know what the difference would be between these batteries and say, Trinity's batteries or Orion's, etc. As far as these cells being matched, the best thing that could happen is these cells could all be virgin cells and matched after you build.

Soldering batteries is my forte and favorite part of this hobby.
