# Centaurus Lost Vape: the test grid for a dual cell mod > Centaurus Lost Vape: the bench protocol for a dual cell mod, what real wattage, heat and counted runtime reveal that a spec sheet never does. Two cells in one chassis do not simply double the runtime printed on a box. They change the way a device has to be measured, because the current is shared between two cells that will not necessarily age at the same rate. The **Centaurus Lost Vape** family is a useful case study for that grid, since the range covers both layouts: the M100 runs on a single cell, while the M200 and the BT200 are dual cell mods. ## What a bench actually measures on a Centaurus Lost Vape Faced with a box mod of this kind, five quantities structure the protocol: the accuracy of the wattage the screen claims, the way the device holds up over a run of closely spaced puffs, the heat of the chassis and of the cells, the runtime expressed in puffs rather than hours, and the consistency of the vapour from one puff to the next. Those five axes are not read in any order. Wattage conditions everything else, because a setting that is off by a margin distorts the heat reading and the runtime that follows from it. The protocol therefore works through them in sequence, one setting at a time. The starting point is duller than it sounds: copy out the declared figures, dated and attributed, before touching an instrument. Lost Vape publishes a wattage ceiling that varies by model, removable 18650 cells that are not supplied on the dual versions, a colour screen and a 510 connection that takes most tanks sold in Britain. Where two retailers disagree, a bench does not pick the more convenient page. It photographs the device and its menus, publishes its own reading, and flags the divergence in writing. That single habit is what stops a spec sheet error circulating from shop to shop for years. ## Establishing what the Centaurus Lost Vape can hold, not what it displays The maximum figure on a mod describes what the circuit is built to pass. It says nothing about what the pair of cells inside will supply, and that distinction is the whole point of the exercise. The method is arithmetic rather than instrumental. Divide the wattage of the setting under test by the nominal voltage of the pack, which for two cells in series is roughly double that of a single cell, and you obtain the current the pair has to deliver. That figure is then read against the continuous discharge rating printed on the wrap of the cells actually installed, and against the datasheet that the cell maker publishes for that exact model. We do not publish a wattage as suitable, and no reader should take a number from a review as a green light for their own pair of cells. What a bench publishes is the reading method, so that the owner of the device can run the comparison on the cells in their own hand. When the demand exceeds what the datasheet describes, the setting is simply outside the working range of those cells, whatever the screen agrees to show. ## Discharge behaviour over a run of puffs A correct reading on the first puff says nothing about the tenth. This is where the protocol adds a continuous discharge series, which is the part of the grid that separates two mods that looked identical on paper. The method is to fire at a fixed interval, on a coil whose cold resistance has been measured beforehand, noting the voltage across the load at every puff. A voltage that sags progressively while the setting has not moved tells you that either the circuit or the cells are no longer following the demand. On a dual cell chassis, that series is only meaningful with paired cells: same reference, same age, same state of charge at the start. Without pairing, a drop in performance cannot be attributed to the device rather than to an imbalance between the two cells, and the whole run has to be thrown away. ## Heat, a safety reading as much as a comfort one Heat on a dual cell mod is read in two distinct places: the chassis, where the hand rests, and the cells themselves, particularly at the end of a discharge run. The protocol calls for a temperature reading at the same point of the chassis before and after a standardised series of puffs, together with a visual inspection of both wraps. A wrap that is melted, split or lifting is an immediate stop, regardless of what the other readings were doing. That step separates ordinary warmth, which follows from the current being drawn, from abnormal warmth that would point to a circuit fault or a tired cell. The absolute number matters less than the comparison between the two cells of the same device on the same run. ## Runtime and consistency, counted rather than estimated A runtime quoted in hours means very little on a device whose wattage and draw style change from one user to the next. The protocol replaces it with a count of puffs at a fixed setting, taken to cut-off, which any reader can repeat. Consistency is measured alongside it, by comparing the voltage and the delivered power between the first and the last puff of the run. A wide gap translates into something the user genuinely feels, thinner vapour towards the end of a charge, without the screen ever mentioning it. That reading is then repeated with a higher resistance coil, because the two do not load the circuit in the same way. Publishing a single series on a **Centaurus Lost Vape** would describe half of the device and present it as the whole. ## Cell safety, the part that is not negotiable A removable cell mod carries a set of habits that the protocol restates before any run, and that apply just as much to everyday use as to the bench. The pair installed has to be matched: same reference, same capacity, same charging history. Cells travel in a dedicated case, never loose in a pocket alongside keys or coins. A wrap that is damaged, even superficially, means the cell is retired before the next use rather than watched to see whether it worsens. Charging is done on a charger built for that chemistry and that format, and the datasheet for the cell is the only document that describes what it will accept. None of that is an editorial preference. Those habits condition the validity of the measurements as much as the safety of the person taking them. ## Internal charging against an external charger As on any chassis with removable cells, a Centaurus Lost Vape can be charged through the USB port of the body or on an external charger that treats each cell separately. The bench records the charging current on both paths, with a USB tester on the internal route and an ammeter on the external one. That comparison is one of the most revealing readings available on any removable cell device, and we set out the full method in our protocol for testing a [battery charger](/uk/battery-charger/), which transfers to this range without modification. ## What British rules change on the accessories around it Hardware regulation in Britain lands on the tank and on the liquid rather than on the mod itself, which is why a dual cell chassis looks much the same here as anywhere else. Refillable tanks sold in the United Kingdom are capped at 2 ml, and the cartridge listed with the BT200 by British retailers reflects that. Nicotine containing e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml. A listing that advertises a larger tank is aimed at another market, and a bench does not carry those figures across. Vaping products are not for sale to under-18s in the United Kingdom, and that rule covers the cells and chargers sold alongside them. ## Frequently asked questions ### Does the Centaurus M100 follow the same protocol as the M200 or the BT200? The M100 runs on a single cell, which removes the series calculation and the pairing check. The wattage, heat and runtime readings are otherwise identical in method, and the results are simply not comparable between the two layouts. ### Does the Bluetooth on the BT200 change the wattage readings? No. Connectivity alters neither the power circuit nor the current drawn from the cells. It adds a draw of its own, which is captured by the runtime reading in the same way as the colour screen. ### Should a device be tested with cells bought separately or with a matched pair? Both, as two separate runs. The first reproduces the common purchase, often with cells the owner already had. The second uses a new, identical pair to isolate the behaviour of the device itself. ### How do you know whether the displayed wattage is trustworthy? By comparing the calculated current demand against the datasheet of the cells fitted, then checking across a run of puffs that the voltage does not collapse before the end of the setting. Two readings, in that order. ### One cell runs warmer than the other during a run. Is that normal? A slight, stable difference can occur. A gap that widens through the run, or warmth you can feel on one cell alone, means stopping the reading and inspecting both wraps before going any further. ## Related reading - [Vaporesso Gen Max: the test grid for a 220 W box](/uk/vaporesso-gen-max-review/) - [Q16 Pro: the test grid for an MTL starter kit](/uk/q16-pro-review/) ## What the bench keeps from the Centaurus Lost Vape The grid applied to the **Centaurus Lost Vape** range follows a fixed order: the current the setting actually demands compared against the datasheet of the cells fitted, the discharge behaviour over a closely spaced run, the heat of the chassis and of the cells, then runtime and consistency counted in puffs rather than quoted in hours. On a dual cell mod, none of those readings mean anything without a matched pair, protected transport and the immediate retirement of any cell with a damaged wrap. It is that protocol, and not the number engraved on the screen, that takes the measure of a Centaurus Lost Vape. Editorial content for adult readers only.
