I was in remission from my laser addiction but recently relapsed.
I have 2 maglite mods that were done by Jayrob including his battery monitoring module.
They are both two cell for a 32650 battery. (I have several of them.)
Recently I noticed when I had an sxd on my dummy load, that with only 2 of these fully charged cells, I am only able to get a little under 4 amps out of the SXD. I think the 32650s are garden variety lithium ion chemistry.
However, if I run three of them, I can easily get the 4.5 amps that I want for my NUBM44 built.
The driver gets pretty hot and I am not sure I can heatsink it well enough to handle the heat.
Lifetime777 built some 20 mm bore heat sinks for me as well as a 20 mm circular driver holder with a shelf.
I use Deen's ultra-miniature connectors (which can handle the amperage) to allow me to keep the diode module and driver separate from the battery. This allows me to troubleshoot each individual component if necessary and having longer leads allows me to use an inductive current measurement
Can I use the 3 cells or will I burn up both the driver and or the diode?
I am assuming Jarob's battery monitoring system won't burn out....it just will not be able to give the right info since it was designed for two cells.
