Vapcell B30 18650 3000mAh Battery

Vapcell B30 18650 3000mAh Battery

The Vapcell B30 18650 3000mAh Battery is a rechargeable INR cell holding 3000mAh, built for external mod use. It is rated at 20A continuous discharge, with a 35A peak, and nominal voltage is set at 3.60V. Full charge reaches 4.20V, and the cell cuts off at 2.5V once discharged.

It weighs around 48g and measures 18.4mm by 65.0mm, and it is supplied in Gold with a flat top terminal and no built-in protection circuit. The cell is charged away from the mod on a dedicated external charger, and a worn or swollen B30 is simply swapped for a fresh one.

What to Know About the B30

• 3000mAh typical capacity, 2900mAh minimum, at 0.2C discharge
• Rated at 20A continuous discharge, with a 35A peak
• Flat top INR cell, supplied unprotected
• Fits single or dual-cell mods with a standard 18650 bay
• Not compatible with 21700 or built-in battery devices

Features of Vapcell B30 18650 3000mAh Battery

Four figures decide whether an external cell suits a given mod: discharge rating, capacity, resistance and terminal type. The B30 is built around a balance of the first two, and the other two follow from the INR chemistry Vapcell uses.

20A Continuous, 35A Peak Discharge

Regulated and mechanical mods draw current fastest at low resistance and high wattage, so a cell's discharge rating sets how far it can be pushed. A 20A 18650 like the B30 holds that current continuously, with a 35A peak, which covers most single-cell setups without the cell running hot under load.

3000mAh INR Capacity

Capacity and discharge current usually trade against each other in an 18650 cell, and Vapcell has pitched the B30 toward the higher-capacity end at 3000mAh typical, with a 2900mAh minimum at 0.2C. A single-cell mod running at moderate wattage rarely needs a second charge before bedtime, which is the main reason buyers pick a 3000mAh cell over a lower-capacity, higher-drain alternative from the same Vape Batteries range.

14mOhm Internal Resistance

Voltage sag under load traces back to internal resistance, and a higher figure means the cell loses power faster as it empties. At around 14mOhm, the B30 holds its voltage reasonably well from a full charge down toward the 2.5V cutoff, so output near the end of a charge is not drastically weaker than at the start.

Flat Top, Unprotected Cell

Most mod batteries ship as flat top cells rather than button top, and the B30 follows that norm with no raised positive terminal. It also carries no built-in protection circuit, leaving the mod's own regulation to manage voltage and current rather than a circuit built into the cell.

Dedicated External Charging

No charge port is fitted to the B30 itself. Charging is handled on a separate 18650 charger built for lithium-ion cells, and the standard charge current is set at 1500mA. Staying close to that figure keeps a Vapcell mod battery running at its rated cycle life for longer.

How to Fit the B30

Step 1: Take the battery out of its packaging and check the wrap for tears, punctures or exposed metal before it goes anywhere near a mod.

Step 2: Charge it fully on a dedicated external Battery Chargers unit rather than through the mod itself.

Step 3: Line up the flat top against the polarity markings printed inside the battery bay before it goes in.

Step 4: Slide the cell into a mod that takes a single or dual removable 18650, then close the battery bay securely.

Step 5: Keep a spare cell in a case rather than loose in a pocket or bag, since a stray coin or key touching both terminals can short the battery.

Step 6: Replace the B30 once the wrap is damaged or output drops noticeably, rather than continuing to charge and discharge a compromised cell.

What's in the B30 Box

The B30 ships as a single cell, ready to charge before its first use. Nothing else is bundled in with it, so a charger and a case are both worth ordering alongside it.

• 1x Vapcell B30 18650 3000mAh Battery

No charger, mod or carry case is included. The cell is charged and stored separately.

Devices Compatible With the Vapcell B30

An external 18650 bay is all the B30 needs. That bay might belong to a single-cell Regulated Mods device, one half of a dual-cell Box Mods unit, or a mechanical tube built around a removable cell.

It is not built for 21700 or 20700 bays, and it will not fit a device with a sealed, built-in battery. Which cell size a specific mod takes is usually confirmed on the battery compartment sticker or in the manufacturer's spec sheet before ordering.

About Vapcell

Vapcell manufactures high-drain 18650 and 21700 cells for vaping and flashlight use, built around INR chemistry chosen for discharge performance over raw capacity. Every Vapcell 18650 in the range, including the B30, is built to the same standard rather than sold as a budget line.

The B30 sits in that line-up as a 3000mAh, 20A cell aimed at everyday single and dual-cell mods. Vapcell's cells are put through independent discharge testing rather than relying on printed figures alone, with the B30's results running close to well-regarded 30Q-class high-drain cells. Pirate Vapes carries the B30 alongside the wider Vapcell charger range, so a matching charger is never a separate errand.

Stock Up on the Vapcell B30

A spare cell is only useful with somewhere to charge it, so a dedicated charger is worth adding to the same order. A case is worth adding too, if the B30 is going to travel in a bag rather than sit in a drawer. Browse Vape Accessories for both.

A basket past £40 travels on Free Pirate Post. Anything placed before 3:30pm Monday to Friday on Tracked 24 is dispatched that same day, and weekend or bank holiday orders go out the next working day instead. Pirate Vapes runs an age-verified checkout throughout.

Conclusion

The B30 works well as an 18650 battery UK vapers can trust, whether that is a single-cell Vape Mods setup at home or a spare cell carried while the first one charges. It is equally at home as a single spare or one half of a matched dual-cell pair.

For sale to over-18s only, it pairs naturally with a dedicated charger and a case. Browse more external cells and mod parts at Pirate Vapes.

FAQs

What mods does the Vapcell B30 fit?

Any mod built around a removable 18650 accepts this B30 battery, from single-cell regulated devices to dual-cell box mods and mechanical tubes. A 21700 bay or a sealed, built-in battery is the only real block.

Is the Vapcell B30 protected or unprotected?

It is an unprotected cell with no built-in circuit board, which is standard for an external 18650 used in a regulated mod that manages voltage and current limits itself.

What charger does the Vapcell B30 need?

Any dedicated external lithium-ion charger that supports 18650 cells and a charge current around 1500mA works. It should never be charged through a USB port built into a mod.

How long does a full charge last?

That depends on the wattage a mod runs at. At moderate power on a single-cell setup, a full charge from this 3000mAh battery typically covers a day of regular use.

What colour is the Vapcell B30?

It ships in Gold, which is the only finish currently listed for this model.

Can two Vapcell B30 batteries be used together in a dual-cell mod?

Two B30 cells work well together in a dual-cell mod, provided both are the same age and have been charged and discharged evenly. Mixing a new cell with a worn one in the same mod is not recommended.
