SONY VTC4 18650 2100mAh Battery – Flat Top – 30ASold IndividuallyHigh Amps discharge current, great for mech mods and sub-ohm buildsManufacturer’s Specs:Dimensions: 65.0mm (L) x 18.2mm (D)Weight: 45gTypical Capacity: 2100mAhMin Capacity: 2000mAhMax Continuous Discharging Current: 30ADischarge cut-off voltage: 2.5VVoltage: 3.7VFull Charge Voltage: 4.2V Safe chemistry LiMN means reduced risk of venting with flame or explosion. Due to the safety inherent in IMR safe chemistry batteries there is no protection circuitry added or built in. This provides a slightly shorter battery length to enable a good fit in most mods.To ensure longevity, it is not recommended to allow the battery to discharge below 2.5V.Please note that due to their inherent safety, IMR cells don’t have a protection circuit built in. They should never be discharged below 2.5 volts or cycle life/performance will be reduced. Maximum charge voltage is 4.25 volts.
