The HOTA F6 Ultra is a high-power 4-channel AC/DC smart charger designed for pilots who need to charge multiple battery packs quickly and independently. Each channel supports up to 15A charge current and up to 250W output on DC power, giving the charger a combined capability of up to 1000W across four channels.
With its built-in AC power supply, the F6 Ultra can also deliver up to 500W total charging power directly from a standard AC outlet. Advanced GaN + SiC power technology helps improve efficiency, thermal performance and power density while keeping the charger compact for a four-channel design.
Four Independent Charging Channels
The F6 Ultra allows up to four batteries to be charged independently at the same time. Each channel can run its own charging, discharging or storage program, making it especially useful for RC helicopter pilots who need to prepare several 6S packs for a flying session.
- 4 independent charging channels
- Up to 15A charge current per channel
- Up to 250W per channel on DC input
- Up to 1000W total DC charging capability
- Up to 500W total charging power from AC input
GaN + SiC Power Technology
The F6 Ultra uses Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductor technology to improve power density and efficiency while reducing heat generation. This allows HOTA to combine a powerful AC power supply and four charging channels in a relatively compact enclosure.
