SXmini G Class V2 Box Mod

SXmini G Class V2 Box Mod

The SXmini G Class V2 Box Mod is an advanced dual-18650 vape mod built for experienced users who want precise control over power, temperature and coil performance. Powered by the YiHi SX750 chipset, it delivers an adjustable 10-200W output with fourth-generation Temperature Control, Smart Boost intelligent preheating and custom power curves. A 1.3-inch TFT IPS colour screen and joystick interface provide access to its settings, while 2.4GHz Wi-Fi supports compatible firmware and interface updates through SX-Panel. The G Class V2 supports tanks up to 30mm in diameter and is supplied without batteries or a tank.

YiHi SX750 Performance

The YiHi SX750 chipset provides variable wattage from 10W to 200W, making the G Class V2 suitable for a wide range of compatible sub-ohm tanks, RTAs and RDAs.

Five memory profiles allow settings to be saved for different atomisers or coil builds. Custom power curves and selectable power-delivery settings also let experienced users adjust how quickly the coil heats and how the output develops throughout each draw.

Smart Boost evaluates the connected coil and applies additional initial power when required, helping larger coils reach the selected operating level more quickly.

The chipset has a protective coating, although the complete mod should not be treated as waterproof.

Dual 18650 Battery Configuration

The SXmini G Class V2 is powered by two removable 18650 batteries, which are sold separately.

Using two cells provides greater output headroom and potential runtime than a single-battery mod. Actual battery life will depend on battery capacity, selected wattage, coil resistance and frequency of use.

Always use a matched pair of authentic 18650 batteries of the same brand, model, age and charge history. Never install batteries with damaged wraps, dents or corrosion.

Pair the device with the Vap Procell 18650 3700mAh Battery Pair.

Temperature Control and Smart Boost

The G Class V2 features fourth-generation Temperature Control with stated resistance-reading precision of 0.0001Ω.

Temperature Control supports compatible coil materials including SS316L stainless steel, Ni200 nickel, titanium and custom TCR settings. When correctly configured, it regulates power according to changes in coil resistance for more consistent temperature management.

The coil resistance should be read and locked while the atomiser is at room temperature.

Wi-Fi, Display and Controls

The SXmini G Class V2 supports 2.4GHz Wi-Fi for compatible updates and customisation through SX-Panel.

Depending on the available firmware and software, SX-Panel can be used to:

• Download firmware updates
• Install supported interface themes
• Change wallpaper backgrounds
• Rename memory profiles
• Add compatible language options

Wi-Fi is optional and is not required for normal operation.

A 1.3-inch TFT IPS colour screen displays the selected wattage or temperature, coil resistance, voltage, battery levels, active mode and puff information. Settings are controlled using the firing button and five-way joystick.

Tank Compatibility and Construction

The G Class V2 uses a spring-loaded 510 connection and supports tanks and atomisers up to 30mm in diameter without overhang.

The body combines zinc and aluminium components and measures approximately 94 × 47.7 × 34.3mm. The device weighs approximately 150g without batteries or a tank.
