Safe for sub-ohm and/or microcoil builds. These batteries have been tested for safety under extreme stress.
Please note that due to their inherent safety, IMR cells do not have a protection circuit built in. They should never be discharged below 2.5 volts or cycle life/performance will be reduced. Maximum recommended charge voltage is 4.17V – 4.20V volts. Please check your cells with a volt meter during initial charging to be sure that your charger cuts off below this level, or cycle life will be reduced.
