Description
The Fogstar Energy 18650 “Dark Blue” (FS4000) is a specialist high-capacity cell designed to maximise run-time for low-power vaping setups. Boasting a massive 4000mAh capacity, this battery offers significantly longer life between charges compared to standard 2500mAh or 3000mAh cells, making it an exceptional choice for Mouth-to-Lung (MTL) vapers who prioritise endurance over raw power.
It is crucial to note that this battery has a Maximum Continuous Discharge Rating (CDR) of 10A. This makes it strictly suitable for low-wattage applications (typically under 20W in a single-battery device). It is not suitable for high-wattage sub-ohm vaping or “cloud chasing” setups, as exceeding the amp limit can be unsafe and will trigger “low battery” warnings on your device.
However, for vapers using a box mod with a high-resistance MTL tank (such as a Nautilus or Zenith) at modest power settings, the Fogstar FS4000 delivers unparalleled longevity, allowing you to vape for days rather than hours. Supplied with a protective PVC case for safe transport.
