Description - Vapcell U30 18650 3000mAh 30A 3.7V Battery
The Vapcell U30 is a high-drain rechargeable 18650 cell built for experienced vapers running external battery devices. It combines a 3000mAh nominal capacity with a 30A continuous discharge rating, making it a practical choice for regulated box mods, advanced vape kits and rebuildable setups that demand consistent current output. Built on Li-ion INR chemistry and finished in a distinctive gold wrap, the U30 is designed to deliver reliable performance across daily sessions.
This is not a battery for beginners or users with built-in battery devices. The Vapcell U30 is an unprotected external cell intended for adults who already understand safe battery handling, proper charging and external cell care. Order a single cell or pick up two at once for a matched pair in dual-battery mods, with fast UK delivery available on all orders.
Why Choose the Vapcell U30 18650 3000mAh 30A Battery?
Battery format: 18650 external rechargeable cell, 18.10mm x 65.00mm, gold wrap
Nominal capacity: 3000mAh (2900mAh minimum rated), supporting longer use between charges
Discharge rating: 30A continuous / 45A max short discharge, suitable for compatible high-drain regulated mods
Nominal voltage: 3.7V, with a 4.2V max charge voltage and 2.7V discharge cut-off
Chemistry: Li-ion INR, a chemistry suited to high-current output
Charging: CC/CV method, 1500mA standard charge current, 3A rapid charge supported
No built-in BMS: This is an unprotected cell. It requires a compatible external charger and responsible handling by an experienced user
Target user: Experienced vapers running regulated box mods, single or dual-battery mods, rebuildable setups and advanced kits that accept removable 18650 cells
Device matching: Not suitable for devices requiring 21700, 20700 or protected cells unless the device specifically states 18650 compatibility
The U30 balances capacity and discharge performance in a format that suits a wide range of advanced external battery devices, making it a solid everyday choice for experienced vapers who already know how to handle cells properly.
Vapcell U30 Performance and Compatibility
Compatible devices: Regulated box mods, variable wattage mods, single battery mods, dual battery mods and advanced kits designed for removable 18650 cells
Wattage context: At 3.7V nominal, a 30A continuous discharge rating supports output up to approximately 110W. Independent bench testing confirms strong, stable performance between 30W and 90W, covering the range most regulated mod users actually vape at
Real-world capacity: Minimum rated capacity is 2900mAh. Expect consistent runtime in this range with low voltage sag at typical vaping wattages
Charging: Use a dedicated external battery charger for the safest and most accurate charge cycle. The U30 supports rapid charging at 3A, but standard 1500mA is recommended for daily use
Dual-battery pairing: If your device takes two 18650 cells, always use a matched pair: same brand, same model, bought together and kept on the same charge cycle. Mismatched cells in a dual-battery mod discharge unevenly, reducing both performance and cell lifespan
Wrap condition: The battery wrap is part of the cell's protection. Check it regularly and replace it with a compatible battery wrap if it shows any sign of tearing or damage. Never use a damaged cell in any device
Pairing the Vapcell U30 with the right charger and using matched pairs in dual-battery mods keeps performance consistent and maximises the cell's service life.
Vapcell U30 18650 Battery Highlights
The Vapcell U30 is built for users who want a high-capacity 18650 cell with a strong discharge rating for everyday use in advanced devices.
3000mAh nominal capacity for extended use between charges

45A max short discharge current
Li-ion INR chemistry optimised for current output

Consistent performance with minimal voltage sag at typical vaping wattages
Gold wrap finish for easy identification in multi-battery setups
These specifications make the U30 a dependable workhorse for experienced vapers who need a reliable 18650 vape battery they can trust across daily sessions.
What's In The Box?
1 x Vapcell U30 18650 3000mAh 30A 3.7V Battery
This product ships as a single cell. If your device requires two 18650 batteries, order a matching pair at the same time to keep the cells properly matched from the very first charge cycle.
Battery Safety Guidance
The Vapcell U30 is an unprotected external cell with no built-in Battery Management System (BMS). That means there is no onboard circuitry to catch overcharge or over-discharge events, so responsible use is essential.
Only use with compatible devices that accept unprotected 18650 cells. Always check your device manual before use
Never use the battery if the wrap is torn, loose or damaged. Replace the wrap or retire the cell
Store in a protective battery case when not in a device. Never carry loose in a pocket or bag alongside keys, coins or metal objects
Charge using a suitable external vape battery charger. Do not rely on in-device charging as the primary charging method
Do not exceed the battery's rated limits. Do not overcharge, over-discharge, short circuit or expose to high heat
If using in a dual-battery device, always use a matched pair: same model, same age, same charge history
Keep away from children and pets at all times
Recycle responsibly through a designated battery recycling point when the cell reaches end of life
Vaping 101 stocks the full range of Vapcell batteries alongside compatible chargers and accessories, with fast UK delivery and genuine stock across the entire 18650 battery collection. Whether you need a single cell or a matched pair for a dual-battery mod, you'll find competitive pricing and reliable availability every time you order.
