The SXmini G Class mod by YiHi features a dual battery configuration with the new SX550J TFT-Bluetooth processor which provides up to 200W power output. The new SX550J board includes support for temperature limiting when using Ni200 or Titanium and Stainless Steel coils and the chip also has options for setting up specific temperature variable settings for special wire types (TCR). Featuring a large full-colour display that is customisable in the menu, Bluetooth connectivity with a smartphone app*, and a joyestick control for the feature rich menu. The user can easily change the font, language, background image, and even display a clock when idle.

We strongly recommend purchasing a pair of new AW IMR 18650 3000mAh or Efest IMR 18650 3000mAh cells to use in this device and "marry" them for life. The cells will need to be kept in a pair and discharged and charged at the same rate throughout their life or poor performance may result.
