LIFT4 (legacy)

The LIFT4 was Lift's flagship before the LIFT5 and LIFTX. It's no longer sold new, but many riders are still on it and still need parts, support, and warranty service. The LIFT4 introduced features that carry forward today: Quiet Ride Technology, the Lift Connect System (LCS), carbon-fiber latches, and the Camber Pro front wings.

Board sizes

4'2 Pro, 4'9 Sport, 5'4 Cruiser, 5'9 Explorer — all carbon fiber, handmade in Puerto Rico. Masts: full carbon, 28" or 32".

Battery & charging

• Gen4 Full Range: up to 2.5 hours, ~50-minute charge

• Gen4 Light: up to 1.5 hours, under 30 minutes to charge

• Uses the standard Lift charger (same as Gen3). Full Range and Light are interchangeable.

Compatibility

Works with LIFT4: all bolt-on front and back wings (Camber Pro, Glide, Surf V2, High Aspect…), 28"/32" carbon masts, Gen4 (native) and Gen3 batteries (with the right data cable), the Elite and Classic hand controllers.

Does NOT work: Gen5 and LIFTX batteries (different form factor and wireless pairing), LIFT5/LIFTX eBox and LCS propulsion. The LIFT4 eBox will not run in a LIFT3 carbon board, but is compatible with LIFT3 F fiberglass boards.

Carries forward to LIFT5: bolt-on Camber Pro and Glide wings, and the Elite Hand Controller (with firmware 1.02.46). Gen4 batteries and the Gen4 charger do not carry forward.

Most common service issue: eBox failure

Symptoms: propulsion makes a high-pitched noise, the board can't get on foil despite the prop spinning, or the controller stays on even with batteries removed.

What to do: if you can swap the propulsion to a second eFoil and it works there — but a known-good propulsion fails on your LIFT4 — the eBox is the issue. A controller that won't power off even with batteries removed is a hardware failure. The standard resolution is warranty replacement of the eBox. See eBox failure.
