IDK so here's some quotes from the Vamo battery thread.
kiwivap: Don't use ICR batteries - yes, its a bad idea to use them. You need to use IMRs with this mod. IMRs have safer chemistry and can handle high drain.
Underwhelmed: An ICR is just an unprotected Lithium Ion battery.
IMR is "safer chemistry" and should vent instead of exploding, especially if you should want to stack 2 18350's.
AW or Efest IMR batteries are the way to go.
