HEPF Voltario T75 Battery Switch with Telemetry

The T75 is a powerful digital redundant power switch with advanced telemetry features and touch switch functionality. It combines backup battery charging circuitry and telemetry with touch with LED (included), optional slide, wireless (R3/RSW), or mechanical switch functionality in a single device.

The T75 is ideal for medium-sized models where high-voltage servos are used without voltage stabilization.

It offers telemetry and monitors:

• Voltage/V
• Capacity/mAh
• Current/A (dual Rx batteries or BEC with backup battery)

of both power inputs.

The T75 is suitable for models equipped with either two receiver batteries or an ESC battery eliminator (BEC) as the primary power source, combined with a small backup battery. The device prioritizes its primary battery input while automatically switching to the secondary input in case of a voltage drop. The charging circuit can optionally be activated to charge the secondary backup battery from the primary input/BEC.

When used with an R3/RSW Wireless Switch, you must change the T75's setting from "Touch" to "Standard". For long-term storage, the backup battery must be disconnected due to the constant load of the R3/RSW Wireless Switch.

The T75 is designed to switch the electronics in your model ON/OFF; it can also replace a mechanical switch. The device remembers its last operating state, and if the battery is accidentally disconnected, the T75 automatically restarts as soon as the battery is reconnected.

Using a mechanical switch instead of a touch switch

• Connect T60 to Jeti Box – red cable + E-battery
• under "Settings" – "Switch Type" change from "Touch" to "Mechanical"
• solder a servo connection cable to a 2-pole switch, only the "Black" and "Yellow/White" cables - please insulate the "Red" one!
• Plug the servo cable into the T60 instead of the touch switch
• Test
