HOTA F6 Ultra 4x 125/250W

HOTA F6 Ultra is a powerful four-channel charger designed for charging RC batteries. It features an integrated 500W power supply for easy AC operation from a wall socket. For field charging, the charger also includes a DC input via XT90 connector. When powered by an external DC source, it supports a total output of up to 1000W (250W per channel). The charger can also run in synchronous mode, allowing two channels to charge a single battery with up to 500W. Another practical feature is the DC power supply mode, where the F6 Ultra can output adjustable voltage between 5–29V with a current limit of 0.1–15A and maximum output power of 250W. It also includes a USB-A 5V/2A output for charging transmitters or action cameras.

Besides charging, the HOTA F6 Ultra also supports discharging. Batteries can be discharged internally at up to 12W per channel or discharged back into the input power source at up to 250W per channel. The F6 Ultra is further equipped with a servo connector that can send PWM/PPM signals for use as a servo tester, or receive and measure them for verifying RC receiver function. All information is displayed on a 2.8" IPS color screen with a resolution of 320x240 pixels.
