Battery Negative to Case?

Recommended Posts

I am building up a ABM-1 enclosure and they supply a try for a 20700 that joins the battery negative to the case metal/atomizer.

See: http://analogboxmods.ca/image/cache/catalog/parts/battery_holders/20700/ABM1-1x20700-2-800x700.jpg

So, I will still run a negative from the battery to the chip for charging, but two questions:

Will this work?  I have never run battery negative to the case before

Do I need to also wire it to the chip output end ground?  I think not since the case is metal and the ground path would then be the screws.

Thanks for your input.  Not clear on why the battery negative is run to the case.

Output Gnd and Batt- are internally connected within the board, my opinion is that it will work just fine with or without the Batt negative wire from sled to board. 

Yes the output ground will need to be attached to the 510 ground.

Thanks.  Been a while since I put one together...been buying LostVape gear but they have imploded and I can't find a decent mod with an evolve chip for love nor money.

A DNA75C with it's up to 100 watt boost (INT firmware) and a 21700 is a pretty capable device. That's a nice one.
