2 newer builds using less common batteries

This build has the largest heatsink in my collection made by Rich. Its an aluminum shell with a copper core. The focus ring has been threaded for a Sanwu beam expander. The diode in this host is a NUBM07 with the stock can intact. Its powered by the Blackbuck 8 amp driver, 2 26350 batteries, and has a 3.75 turn 10k ohm Bourne potentiometer with a brass knob also made by Rich. I don't have a power rating due to killing the LPM sensor while testing (won't be testing HP gball diodes anymore).
