HOTA D6 Ultra is a powerful dual-channel charger designed not only for 1–6S LiPo batteries. The charger features an integrated power supply with up to 300W output, allowing for fast charging when powered directly from a wall socket. Thanks to GaN technology, the internal PSU delivers higher performance while keeping the unit compact. For field charging, the charger can also be powered through a DC input via an XT60 connector. Supported input voltage is 6.5–30V. When supplied with DC voltage above 24V, the charger can output up to 325W per channel (650W total). In addition to the two main XT60 outputs for battery charging, the unit also includes a USB-A 5V/2.1A port and a pad for wireless charging.
The charger supports all common cell chemistries including NiCd, NiMH, LiPo, Li-Ion, LiHV and more. Charging parameters are set using a rotary dial and button, while all relevant data is displayed on a bright 2.8" color screen. Besides charging, the HOTA D6 Ultra also supports discharging. Internal discharge power is limited to 15W, but with an external load it can discharge up to 350W per channel.
