Thelema Solo 100 Pro
A single-battery box mod built for experienced sub-ohm vapers, delivering up to 100W from one 18650 or 21700 cell via the Quest X 3.0 chipset.
Set up guide & tips
This is a mod-only device. You will need a compatible sub-ohm tank, an external battery, and the right e-liquid before your first vape.
Step 1 - Choose and Install Your Battery
The Thelema Solo 100 Pro takes a single 18650 or 21700 cell, sold separately. Neither is included. A 21700 is the better everyday choice at higher wattages as it holds more capacity and can handle sustained output more comfortably than most 18650 cells. An 18650-to-21700 adapter ships in the box, so your existing 18650s will still fit.
To install, open the magnetic battery cover at the base of the mod. Observe the positive and negative markings inside the battery bay and insert the cell accordingly. The cover is magnetic and seats firmly in either orientation, though there may be a small amount of play due to material tolerances at temperature. That is normal.
Battery safety note: only use high-discharge 18650 or 21700 cells from reputable brands. A cell rated at 25A continuous discharge or above is recommended for use at full power.
Step 2 - Attach and Prime Your Tank
The Thelema Solo 100 Pro is compatible with any sub-ohm tank with a coil resistance between 0.1 and 3.0 ohm. The Lost Vape Centaurus Sub Ohm V2 Tank is the natural pairing, using UB Max coils in 0.15, 0.2 and 0.3 ohm options.
Before filling, prime the coil. Remove the coil from the tank, apply two to three drops of e-liquid directly onto the exposed cotton wicking ports on the side of the coil, and re-seat it. This saturates the cotton before heat is applied and prevents a harsh, burnt first hit.
Step 3 - Fill the Tank
UK TPD note: the Centaurus Sub Ohm V2 Tank sold in the UK holds 2ml in its TPD-compliant configuration. This is the legal maximum for refillable tanks under UK TPD regulations. The tank is designed to accept larger glass sections, but the 2ml straight glass is what you will receive as standard.
To fill, use the twist-and-slide top fill mechanism. Twist the top cap to unlock it, slide it open to reveal the fill port, add your e-liquid, then twist it back to lock. Once filled, leave the tank to stand for at least five minutes before firing to allow the coil to fully saturate.
Step 4 - Choosing Your E-Liquid
Sub-ohm tanks running at 60W to 90W need high-VG e-liquid, typically 70VG/30PG or higher. Thinner, high-PG liquids will flood these coils and can cause leaking and a harsh, unpleasant vape.
- Shortfills (50ml or 100ml): the practical choice for regular DTL vapers. Most are 70VG or above.
- Nicotine strength: at this wattage and airflow, 3mg to 6mg freebase nicotine is appropriate for most vapers. The large vapour volume means even 3mg delivers a noticeable hit.
- Nic salts: not suited to sub-ohm use at high power. Nic salts are designed for low-wattage pod systems. Do not use them in this setup.
Step 5 - Powering On and Setting Your Wattage
Press the fire button five times quickly to power the device on or off. Three presses of the fire button opens the main menu, where you can select your vaping mode. For most users, WATT mode is the right starting point. Use the plus and minus buttons to adjust wattage.
Start at the lower end of your coil's rated wattage range and work upward over a few puffs until the flavour and warmth suit you. Firing above a coil's maximum rated wattage will burn it out quickly. Hold plus and minus simultaneously to lock and unlock the wattage adjustment buttons.
Available modes: WATT, BOOST, VOLTAGE, SS316 (temperature control), Ti (temperature control), Ni (temperature control). BOOST mode adds a brief power spike at the start of each puff, which can help with coil ramp-up. Temperature control modes are for specific wire types and require matching coils.

Does the Thelema Solo 100 Pro come with a tank?
No. The mod is sold separately without a tank. It is compatible with most sub-ohm tanks in the 0.1 to 3.0 ohm resistance range. Lost Vape's Centaurus Sub Ohm V2 Tank is the intended pairing and uses UB Max coils in 0.15, 0.2 and 0.3 ohm variants.
Which battery should I use with the Thelema Solo 100 Pro?
A 21700 high-discharge cell is the stronger choice at higher wattages, offering more capacity and better sustained output than most 18650 options. An 18650-to-21700 adapter is included in the box. Use cells with a continuous discharge rating of 25A or above. Batteries are not included and must be purchased separately.
How do I charge the Thelema Solo 100 Pro?
The mod charges via the USB-C port at 5V/2A. For best battery longevity, a dedicated external charger is recommended so you can swap a fully charged cell rather than relying solely on in-device charging. Charging in-device is fine for occasional use, but external charging protects cell health over time.
Why does my tank only hold 2ml when I have seen larger versions online?
UK TPD regulations set a 2ml maximum capacity for refillable tanks. The 2ml straight glass section is the legal standard version sold in the UK. The Centaurus Sub Ohm V2 Tank is designed to accept alternative glass sections, but the 2ml configuration is what complies with UK law and what you will receive from a UK retailer.
Can I use nic salts in the Thelema Solo 100 Pro?
No. Nic salts are formulated for low-wattage pod devices and should not be used in a high-power sub-ohm setup. At 60W to 100W with a DTL tank, the nicotine delivery would be excessive and potentially unpleasant. Use freebase nicotine in a high-VG shortfill, typically at 3mg to 6mg strength.
