Ursa Nano V2 Replacement Pod: Lost Vape URSA Cartridge V2
The Ursa Nano V2 replacement pod is Lost Vape’s URSA Cartridge V2: the side-fill pod for the URSA Nano, Nano Pro, Nano 2, Nano Pro 2, Baby Pro and Baby 3. We carry it in 0.6Ω and 0.8Ω, the two resistances Lost Vape launched it with.
Lost Vape rates the V2 for 10+ refills, gave it a double leak-resistant base, and made it interchangeable with the first URSA cartridge.

Ursa V2 Pod: 0.6 vs 0.8 Ohm
Lost Vape’s V2 chart runs from 0.6Ω, recommended for freebase at a restricted direct-to-lung draw, up to 1.4Ω for nic salts at a mouth-to-lung draw. We stock the first two steps. Lost Vape doesn’t publish a wattage for each cartridge.
| Resistance | Lost Vape’s guidance | Best with |
|---|---|---|
| 0.6Ω | The freebase, RDL end of the range | 50/50 freebase, or 10mg nic salts for more vapour |
| 0.8Ω | One step towards the nic salt, MTL end | Our pick for nic salts – the tighter of the two |

Which Devices Does the Ursa V2 Pod Fit?
Lost Vape lists the V2 cartridge for the URSA Nano Pro, URSA Nano, URSA Nano Pro 2, URSA Nano 2 and URSA Baby Pro, and its URSA Baby 3 page says that device is fully compatible too.
The Lost Vape Ursa Cap Pod Kit we sell takes these pods: Lost Vape lists the URSA Cap as URSA Cartridge V2 compatible, and the kit ships with one in the box. The same cartridge also fits the URSA Nano, Nano Pro, Nano 2, Nano Pro 2, Baby Pro and Baby 3, and Lost Vape describes the newer URSA Cap Pro as compatible with the URSA cartridge series. For the Nano S3, Lost Vape lists the top-fill URSA Cartridge V3 instead.
Will not fit: devices from other brands. Lost Vape doesn’t list the V2 cartridge for the URSA Nano S, Nano Pro S, Nano 3, Nano Air or the original URSA Baby, so we can’t confirm a fit for those.

How to Fill and Prime an Ursa V2 Pod
- Take the pod out of your URSA device.
- Open the refilling plug on the side – the tab is marked OPEN.
- Fill through the slot, stopping just short of the top.
- Press the plug back to seal the pod, then put it back in the device.
- Lost Vape’s manual says to leave a newly filled pod for at least five minutes before vaping, and never to fire it dry.

How Long Does a Pod Last?
Lost Vape rates the V2 cartridge at 10+ refills and says the upgrade gives it a longer service life and more precise atomisation. The coil is part of the cartridge, so when flavour dulls or tastes burnt, replace the whole pod.
Ursa V2 Pod Troubleshooting
| Problem | Likely cause and fix |
|---|---|
| Leaking at the side | The OPEN plug isn’t fully closed. Press it in along its whole length. |
| Burnt taste on a new pod | It wasn’t primed. Give the next one at least five minutes after filling. |
| Pod not firing | Wipe the contacts on the pod and in the device, then reseat the pod. |
| Flavour tailing off | The coil is worn. Swap in a fresh cartridge. |
Ursa V1 and V2 Cartridges Are Interchangeable
Lost Vape designed the V2 so you can switch freely between it and the original URSA cartridge. If you have V1 pods left over, they still fit. Don’t confuse either with the Top Fill URSA Cartridge V3, a separate pod that fills from the top.
A Double Leak-Resistant Base
Lost Vape gives the V2 a double leak-resistant construction against condensed liquid at the base, and a curved mouthpiece for comfortable draws.

Best E-Liquids for These Pods
Lost Vape says the V2 handles freebase and nic salts, at either a restricted lung or a mouth-to-lung draw. For the 0.6Ω, 50/50 freebase from our 10ml e-liquids is the match. For the 0.8Ω, our nic salts at 10mg or 20mg. Avoid thick high-VG shortfills, which wick too slowly for a small pod coil. Not sure which nicotine to choose? Read nic salts vs freebase nicotine.
