Efest Purple IMR 18650 20A 3100mAh 3.7v Rechargeable Flat Top Batteries [2 Cells/Pack]
Genuine Single Efest IMR 18650 LiMn 3100 mAh Battery Flat Top. These batteries have a lower internal resistance and therefore will deliver more current under a heavy load than most lithium 18650s when used in a high-drain e-cig, or vaporizer. Efest was able to dial these huge batteries to 20A continuous maximum discharge making them fantastic for unregulated / mechanical mods, however they will work just as fine in a VV/VW regulated mod as well.
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.
