KZ Box Mod

[fire8spitter]

I recently ordered one, it's a wooden box mod with 2 18650 batteries in parallel. The switch is rated 6 amps with no MOSFET. All contacts are copper. Is this safe to subohm at around .3-.5? If not ten would I be able to add a MOSFET in to make it safer?

No to both questions.
If the switch is rated a 6 amps then the lowest you can run would be .7 ohms, however the KZ website says they use 5 amp switches, which would leave you at a safe resistance of .84 ohms.
This is also providing any wiring used in the box is thick enough to handle the load.
