Please verify that you have the correct battery for your application.
ICR (LI-Ion) batteries are considered chemically unsafe and are the batteries that may explode violently.
UNPROTECTED ICR batteries should never be used in a mechanical mod, and protected batteries are not intended for regulated Mods.
A protected ICR battery does not prevent an ICR battery from violently exploding.
IMR batteries are recommended for mechanical and regulated Mods.
Never Mix high capacity batteries with extended capacity Batteries.
Do not mix batteries, or stack batteries.
If you sub-ohm you must use a battery over 10 - 20 Amp CDR (Continuous Discharge Rate) or greater depending on how low the ohms is. As the ohms decrease the CDR will need to increase. Please ensure that you have the correct battery.
Two equal coils in parallel will cut the ohms in half thus requiring a greater CDR.
You must verify that the battery will work with the coil!
