HOTA F6 Ultra Quad-Channel AC/DC Smart Charger (GaN)

The HOTA F6 Ultra is a quad-channel smart charger built for FPV and commercial drone pilots who cycle multiple battery packs per session. By utilising an advanced Gallium Nitride (GaN) internal power supply, this charger delivers four independent AC/DC charging channels while maintaining a physical footprint significantly smaller and cooler than traditional multi-channel bench chargers.

Key features

• Four independent ports for simultaneous charging, discharging and balancing of different battery capacities and chemistries.

• Internal GaN circuitry sharply reduces physical size and excess heat generation during high-power AC operation.

• Dual AC/DC inputs for a seamless transition between wall outlets at home and large DC field batteries on location.

• Bright full-colour display for real-time monitoring of individual cell voltages, internal resistance and charge capacity.

Specifications

• Input power: AC 100-240 V / DC 6.5-30 V (DC input via XT90)

• Charge power: AC 500 W total; DC 250 W x 4 (1000 W) at input above 24 V; two channels can combine for 500 W on one pack

• Charge current: 0.1-15 A x 4

• Balance current: 1000 mA x 4

• Discharge: internal 12 W x 4; regenerative 250 W x 4

• Supported cell count: 1-6S (LiPo, LiHV, LiFe, Li-Ion)

• Other chemistries: NiMH/NiCd/NiZn 1-16S, Pb 2-24 V

• DC power supply mode: 5-29 V, 0.1-15 A, up to 250 W

• USB output: 5 V / 2.1 A

• Display: 2.8-inch IPS, 320 x 240

• Power technology: Gallium Nitride (GaN)

• Channels: 4x independent

• Dimensions: 115 x 126 x 87 mm

• Weight: 945 g

By providing four dedicated output ports, this charger eliminates the risks associated with parallel charging boards, offering precise individual cell management for freestyle builds, racing quads and heavy-lift cinelifters.
