Sony’s VTC4 18650 battery is legendary in the vaping world. It is a high-drain lithium ion with an incredible 30 amp continuous discharge rating and an impressive 2,100 mAh capacity. It is the only battery we recommend for use in mechanical mods, as it is the safest battery available for high-wattage vaping.
Warning: Only use mechanical devices at your own risk. Even extremely safe batteries like the Sony VTC4 can be pushed beyond their limits. You should be incredibly knowledgeable and diligent when using mechanical devices.
