Lost Vape Centaurus tank, what it asks of your mod and batteries
Product listings talk about clouds, flavour and top filling. None of them says what the Lost Vape Centaurus tank demands from the mod it sits on. Yet this sub-ohm tank runs between 40 and 100 watts depending on its coil, a range that puts real load on your batteries.
Before buying one, it is worth knowing whether your hardware can keep up. This article does the maths, from the current drawn from each cell to the number of puffs a single charge can be expected to deliver.
Which mod does the Lost Vape Centaurus tank need?
The Lost Vape Centaurus tank needs a regulated mod able to deliver 60 watts to cover the whole range of its gentlest coil (0.3 ohm, 40 to 60 W), and 100 watts to make full use of the lowest. A dual-battery mod is the comfortable choice. A single-battery mod still works with the 0.3 ohm coil, provided its cell can handle the current involved.
Diameter matters too. Retailers list the tank at 26 mm, so a mod designed around slimmer tanks will leave it overhanging. Its standard 510 connection screws onto any mod that uses that thread.
What the manufacturer’s specification says
The current version is the Centaurus Sub Ohm V2. Lost Vape describes it as a top-fill tank with a locking cap that prevents accidental opening, and with airflow at the top. The body is SUS303 stainless steel with a glass tube.
The quoted capacity is 5 ml with the bubble glass or 3 ml with the straight glass. Lost Vape states that every TPD version holds 2 ml, and in the UK refillable tanks are capped at 2 ml, so that is the version British buyers should expect on the shelf.
The TPD kit contains the tank, a spare 2 ml glass, a spare parts pack and two UB Max V2 coils, one at 0.15 ohm and one at 0.3 ohm. The Centaurus name also covers other Lost Vape products, including mods and other tanks such as the Sub Coo and the Nano MTL, which should not be confused with this one.
UB Max coils on the Lost Vape Centaurus tank, and the power they need
The tank takes UB Max coils. Lost Vape publishes three values for the V2 edition, all intended for direct lung vaping, and their wattage ranges do not overlap.
| UB Max V2 coil | Manufacturer’s wattage range | Draw |
|---|---|---|
| X1, 0.15 ohm | 80 to 100 W | DTL |
| X2, 0.2 ohm | 60 to 80 W | DTL |
| X3, 0.3 ohm | 40 to 60 W | DTL |
What those watts mean inside the coil
Ohm’s law turns watts into amps. The current flowing through the coil equals the square root of the power divided by the resistance. At 90 watts on a 0.15 ohm coil that comes to about 24.5 amps. At 50 watts on a 0.3 ohm coil it is about 12.9 amps.
What the mod actually draws from its cells
On the battery side the sum changes. A regulated mod controls its output, and the cell supplies roughly the requested power divided by its own voltage. At 100 watts, a single 3.6-volt cell must therefore deliver close to 28 amps, before any circuit losses. In a dual-battery mod with the cells in series the voltage doubles, and each cell supplies only about 14 amps.
That is the figure to check when choosing cells. The continuous discharge rating, shown as CDR on a cell’s data sheet, has to exceed it with a comfortable margin, and our guide to choosing a vape battery explains how to read it.
Battery life, how many puffs per charge?
A demanding tank drains cells quickly, and the figure can be worked out. A 3.6-volt, 3000 mAh cell stores 10.8 watt-hours. At 80 watts that energy covers about eight minutes of total firing time, or roughly 160 three-second puffs, ignoring losses.
With two identical cells the figure doubles to about 320 theoretical puffs at 80 watts. Circuit losses and the voltage sag towards the end of a charge bring that down in practice. At 50 watts on the 0.3 ohm coil, the same cell lasts 1.6 times longer in theory.
The tank also empties faster than a mouth-to-lung tank, because a coil set at 40 watts or more vaporises more liquid with every puff. Capacity has nothing to do with it, since mouth-to-lung tanks sold in the UK are capped at 2 ml as well. The settings that stretch a charge further are gathered in our guide to vape battery life.
Single battery, dual battery or built-in battery
The choice of mod follows directly from those numbers. Each format has its place, as long as it is matched with the right coil.
The dual-battery mod, the natural partner
It covers the tank’s full range, up to the 100 watts of the 0.15 ohm coil, while sharing the load across two cells. It also carries the most stored energy, and so the most puffs between charges.
The single-battery mod, with the 0.3 ohm coil
A single-cell 21700 or 18650 mod has half the voltage of a dual mod, so its cell delivers twice the amps for the same wattage. The 0.3 ohm coil, set between 40 and 60 watts, is the sensible pairing here.
Built-in batteries, case by case
A mod with a built-in battery lists its maximum output, but rarely the current its cell can handle. The whole unit is designed by the manufacturer for the output it quotes, and staying inside that range is the rule. The trade-off between the two designs is covered in our guide to built-in or removable batteries.
FAQ
These questions come up often before buying a tank this powerful.
Do older UB Max coils fit the Centaurus V2?
One retailer describes the tank as compatible with the UB Max range, and Lost Vape publishes the values for the V2 edition. If in doubt, the tank’s manual is the reference.
Is the Centaurus tank suitable for a tight draw?
No. The three coils published by Lost Vape are all rated for direct lung vaping. For mouth-to-lung vaping, the brand offers a separate tank in the range, the Centaurus Nano MTL.
Why does the listing say 5 ml when the box says 2 ml?
The global listing describes the bubble glass version. In the UK the TPD version comes with 2 ml glass, and the capacity printed on the packaging is the one that applies.
Can the Centaurus sit on a mod with a built-in battery?
Yes, if the mod accepts a 26 mm tank and delivers the power the fitted coil needs. A mod capped below 60 watts limits you to the 0.3 ohm coil.
Should cells be charged in the mod or in an external charger?
Both work, depending on the mod. An external charger has the advantage of checking each cell individually.
The Lost Vape Centaurus tank, power before clouds
The Lost Vape Centaurus tank should be chosen together with the mod that will carry it. Running between 40 and 100 watts depending on the UB Max coil, it draws close to 28 amps from a single cell, and about half that per cell on a dual mod. That figure decides the type of mod, the choice of cells and the battery life to expect.
Before ordering a Lost Vape Centaurus tank, check three things on your mod, its maximum output, the tank diameter it accepts and its cells. The handling rules for hard-working cells are set out in our guide to vape battery safety.
