These are high quality, rechargeable 20700 batteries from Efest, rated to have a 3000mAh capacity and a discharge rate of 30A. These batteries are only for use in mods that explicitly state compatibility with these batteries.
While our current range of chargers do not officially support 20700 batteries due to their length, they are compatible with most battery multi chargers. We have so far tested 20700 cells with the Efest LUC V2 and Nitecore D4 and can confirm that they function as intended. 20700 batteries are not compatible with 18650 mods.
