solderless power tubes for a123 batteries

The silver power paste is only applied in a very small amount which results in really just a light film. I have not seen any evidence that it ever melts or runs when applied this way. I've run SPT's for years without any problems whatsoever.

Solderless connections have less resistance than soldered connections so it makes sense to avoid solder unless absolutely required. With that said, the SPT should be a more efficient pack than a soldered one. The A123 SPT is a great solution for those who would rather avoid Dewalt pack, acquisition, deconstruction, and ultimately resoldering cells in a undesirable side by side formation. Pete also sells a phantom cell so you can run an odd number of cells if desired.
