What Is an 18650 Battery?

The 18650 is the most widely used rechargeable cell format in the vaping industry. The name refers to its dimensions — 18mm diameter by 65mm length. These cells power the vast majority of regulated box mods and many sub-ohm devices. They are rechargeable Li-ion cells charged externally (in a dedicated charger) or via the mod's built-in USB charging circuit.

What Does CDR Mean and Why Does It Matter?

CDR stands for Continuous Discharge Rating — the maximum current (in amps) a cell can safely deliver continuously. The Vapcell K30 has a 15A CDR, suitable for regulated mods at moderate wattages. Using a cell beyond its CDR rating generates excessive heat and can damage the cell. For regulated mods with built-in protection, the mod's chipset will typically limit current draw to safe levels.

What Does 'Unprotected' Mean?

An unprotected cell has no built-in Battery Management System (BMS) circuit. This is standard for vape mod batteries — the protection is provided by the mod's chipset rather than the cell itself. They should only be used in regulated devices with appropriate protection circuits.

How Does the Vapcell K30 Compare to Other 18650 Cells?

The K30 sits in the mid-range — 3000mAh with a 15A CDR. For higher capacity, the ODBXT 3800mAh or Fogstar Energy 4000 offer more mAh. For higher discharge rates, the Molicel P28A is a popular high-drain option. Browse the full Batteries & Chargers range for all available cells.

What is the capacity of the Vapcell K30?

What is the continuous discharge rating?

The Vapcell K30 has a CDR of 15A, suitable for regulated mods at moderate wattages.

Is the Vapcell K30 flat top or button top?

The Vapcell K30 is a flat top cell, compatible with the vast majority of 18650 vape mods.

Does the Vapcell K30 have a protection circuit?

No — the Vapcell K30 is an unprotected cell with no built-in BMS. Protection is provided by the regulated mod's chipset. Use only in regulated devices.

What is the charging voltage and current?

CC/CV at 4.2V (±0.05V). Standard charging: 800mA; rapid charging: up to 3A. Charging temperature range: 0°C to 45°C.

⚠️ Important Safety Information

18650 rechargeable Li-ion batteries can be dangerous if used improperly. Always use in regulated devices with appropriate protection circuits. Never use in mechanical or unregulated mods without thorough knowledge of battery safety. Do not short circuit, overcharge, over-discharge, crush, puncture, or expose to extreme heat. The buyer assumes all associated risks.
