A Proto ERM DNA75

[awsum140]

I finally got around to putting this together this morning.  It's a Proto ERM enclosure that I modified with magnets to hold the back on.  The battery sled is a Keystone and I'm not very happy with it and will be making something more "custom" in the near future.  I do love the DNA75, more than enough power for me.

i like it awsum140! quick question for you. how bad is the voltage sag at 75 watts with that 18650 sled? reason i'm asking is, i'm looking for a single 18650 sled with something more substantial than "bent metal tabs" and heavy springs inside the batt contacts for rock solid connection.

The sag is substantial, say down to 2.5 volts or so, but it's only for the "punch".  I'm vaping at 40 watts and it sags about .2 to .3 volts under that load.  If you find a decent sled that will fit into an ERM, let me know what and where.  This Keystone, while it works, is kind of pathetic for this kind of application.

thanks awsum. with my 75 and the hcigar 3s lipo i rewired for parallel, the most sag i see is 3.8 volts at 75 watts preheat. if i find a sled that looks solid i'll let you know.
