# Lost Vape Centaurus BT200, which tank fits the box

> Lost Vape Centaurus BT200 as a mod only or a kit, the tanks that sit within its 26.9 mm depth, manufacturer diameters compared and overhang worked out.


Almost everything published about the **Lost Vape Centaurus BT200** is a shop listing, for the kit or the mod on its own, while the question buyers actually ask goes unanswered. Should you take the tank that comes in the box, or keep the one you already own? Listings say the mod takes "most" tanks without naming a single one. This guide starts from the one measurement that settles it, the depth of the mod, and sets it against the diameters manufacturers publish.

## Lost Vape Centaurus BT200, mod only or kit depending on your tank

The answer comes down to the tank. Without a direct lung tank, the kit supplies the whole set-up, the mod and a Centaurus Sub Ohm V2 designed for it. If you already have a tank of 24 to 26.9 mm in diameter, the mod on its own is enough, and your tank will sit on it without hanging over the edge.

In between, a wider tank of 28 to 30 mm still works on the **Lost Vape Centaurus BT200**, but it overhangs the mod. That is not a fault, it is a matter of balance in the hand and of looks. The table further down puts a figure on that overhang for six common tanks.

## What comes in the box, mod only or full kit

Lost Vape lists three box contents on the BT200 product page. They mostly show what the mod-only version leaves you to sort out before first use, a tank and a pair of batteries.

### The mod on its own

The mod-only box holds the mod, a USB-C cable and a user manual. No battery is supplied, although the mod needs two 18650 cells. A retailer lists exactly the same contents and states that the mod is sold without batteries.

### The 2 ml TPD kit

Alongside the mod, Lost Vape's TPD kit carries a 2 ml Centaurus Sub Ohm V2, two UB Max V2 coils (0.15 and 0.3 ohm), a 2 ml spare glass and a bag of spare parts. Under UK rules a refillable tank is limited to 2 ml, and nicotine e-liquid is capped at 20 mg/ml in bottles of 10 ml at most, so the larger international versions do not meet UK rules.

## 26.9 mm, the Lost Vape Centaurus BT200 figure that decides

The manufacturer gives 56.9 x 26.9 mm for the cross-section of the mod. The second figure is the depth, the surface the tank stands on. That figure, not the width, decides whether a tank sits flush or overhangs.

Retailers round this figure in different ways, and one listing promises tanks "up to 26 mm without overhang". Rather than trust a rounded number, the calculation below compares each manufacturer's published diameter with the 26.9 mm of the mod, then halves the gap to give the overhang on each side.

| Tank | Published diameter | Gap per side against the mod | 2 ml version |
|---|---|---|---|
| Vaporesso iTank T | 24.5 mm | 1.2 mm inside the edge | yes |
| GeekVape Z Sub-ohm | 26 mm | 0.45 mm inside the edge | yes |
| Lost Vape Centaurus Sub Ohm V2 (smaller figure) | 26.8 mm | 0.05 mm inside the edge | see below |
| Voopoo Uforce-X (TPD version) | 28.4 mm | 0.75 mm overhang | yes |
| GeekVape Z Sub-ohm SE | 29 mm wide | 1.05 mm overhang | yes |
| Voopoo Uforce-X (standard version) | 29 mm | 1.05 mm overhang | no |
| Lost Vape Centaurus Sub Ohm V2 (larger figure) | 30 mm | 1.55 mm overhang | see below |
| GeekVape Z Max | 32 mm body on a 26 mm base | base inside, body 2.55 mm beyond | yes |

Below 26.9 mm, the tank leaves a thin strip of mod showing around it. Above that, it hangs over, and the overhang shows more as it nears two millimetres per side.

## The kit's Sub Ohm V2, 30 or 26.8 mm

The Centaurus Sub Ohm V2 product page publishes two diameters, 30 mm and 26.8 mm, for the same 58.5 mm height, without saying which version each one belongs to. For a buyer the difference matters, as the first overhangs the mod and the second sits almost exactly flush. The page only states that every TPD version holds 2 ml.

A full French review by Oneshot Media, carried out on the kit sold in France, lists the tank at 26.8 mm. That is the best available pointer for the TPD version. It is not a rule for a tank bought elsewhere, and a quick measurement with calipers is worth doing before counting on a flush fit.

## Other brands' tanks on the Lost Vape Centaurus BT200

Fitting a tank from another brand is the main reason to buy the mod on its own. The six tanks in the table fall into two groups, those that stay within the depth of the mod and those that go beyond it.

### Tanks that stay within the depth of the mod

The Vaporesso iTank T, at 24.5 mm, leaves the widest margin, and our page on the [Vaporesso iTank T](/uk/vaporesso-itank-t/) covers its GTi coils. GeekVape's Z Sub-ohm, at 26 mm, lines up almost exactly with the mod, and the [GeekVape Zeus vape tank guide](/uk/zeus-vape-tank/) explains where it sits in the range.

### Tanks that hang over

Voopoo's Uforce-X and GeekVape's Z Sub-ohm SE move up to 28.4 or 29 mm and overhang by roughly a millimetre per side. On the Lost Vape Centaurus BT200, the Z Max is a special case, since its 26 mm base rests on the mod while its 32 mm body widens above it. Our [Voopoo vape tank guide](/uk/voopoo-vape-tank/) covers the brand's PnP coils, the family the Uforce-X draws on with its PnP X heads.

## Before you screw it on, 510 thread and wattage range

Diameter is not the whole story. Two checks remain before fitting a tank that was not designed for this mod.

### A 510 thread

Two retailers list a 510 connector on the BT200, the standard thread for box mods. Most direct lung tanks use it, but the tank's own product page is what counts, and a proprietary fitting made for a pod or a specific kit will not screw on.

### A coil within 5 to 200 W

Lost Vape rates the mod from 5 to 200 W. Every coil of the tanks above falls within that range, from the Uforce-X PnP X tight-draw coils, rated at 10 to 16 W, up to the kit's UB Max V2 heads, set from 40 W for the 0.3 ohm and from 80 W for the 0.15 ohm. The range printed on the coil is still the reference, and our [vape tank guide](/uk/vape-tank-guide/) explains how to read it.

## FAQ

A few practical questions come up once the tank is chosen. The answers below add to the fit table.

### Does a tank that overhangs the mod work normally?

Yes. The overhang has no effect on the electrical contact or on the power delivered. It changes how the set-up balances on a table and how it looks, nothing more, as long as the thread is a genuine 510.

### Can you fit a rebuildable atomiser on the BT200?

A rebuildable atomiser with a 510 thread screws on just like a tank. The same diameter calculation applies, and the coil you build has to stay within the wattage and resistance range the mod accepts.

### Does the mod-only version come with batteries?

No. Lost Vape lists two external 18650 batteries as not included, and the mod-only box contains just the mod, the cable and the manual. You need a matched pair of cells before the first switch-on.

### How can you tell whether a tank uses a 510 thread?

The manufacturer's product page usually states it in the specifications, as "510" or "510 connection". Where nothing is stated, a tank sold on its own for box mods usually is, whereas a cartridge supplied with a pod is not.

### Does a tight-draw tank belong on a 200 W mod?

Yes, since the mod goes down to 5 W. The Uforce-X tight-draw coils, at 0.8 and 1 ohm, are rated between 10 and 16 W by Voopoo, far below the mod's maximum output.

## Lost Vape Centaurus BT200, a mod you choose along with its tank

The kit covers anyone starting from scratch, and the mod on its own covers anyone who already owns a 24 to 26.9 mm tank. Beyond that, the set-up still works, with an overhang that a simple calculation lets you foresee before buying.

The **Lost Vape Centaurus BT200** does not dictate its tank, it dictates a measurement. Comparing a tank's published diameter with the 26.9 mm depth of the mod is the check to make, and it holds for any tank fitted to any box mod.
