These are original LG HE4 18650 high drain batteries with lower internal resistance values that perform extremely well under harder workloads. A step up from HE2 batteries, the HE4 cells are also noteworthy for operating at lower temperatures during peak output periods. As with the HE2 series, HE4 batteries are designed for 22-23mm cylindrical mods and most 18650 box mods. These batteries are considered to be one of the best and safest for low sub ohm vaping purposes because they have a maximum load capacity of 35A.
IMPORTANT: To protect battery performance and ensure long life, it is not recommended to allow the battery to discharge below 2.5V or exceed the maximum charging voltage of 4.2V. Doing so may shorten the life cycle or cause permanent damage to the battery.
