eBox (motor controller)

What the eBox does, which one fits your board, and the data cables it uses.

1 min readUpdated Jun 10, 2026Controllers & Electronics

The eBox is the brain of the eFoil. It sits inside the board's hatch compartment and connects three things: the battery (power), the hand controller (wireless Bluetooth throttle), and the propulsion motor. It comes complete with cooling-line connections, mounting plate, power connector, and data cable.

eBoxes are strictly generation- and board-specific. You cannot run a LIFT3 eBox in a LIFT4 board, or vice versa. Always specify your exact board model and size when ordering a replacement.

Which eBox fits my board?

eBox

Compatible boards

LIFT5/LIFTX

All LIFT5, all LIFTX

LIFT4

LIFT4, LIFT3 F

LIFT3 F

LIFT3 F, New LIFT3 F (two sizes: 4'9", 5'4")

LIFT3

LIFT1, LIFT2, LIFT3 (carbon only)

If you have a fiberglass board (LIFT3 F or New LIFT3 F), you need the LIFT3 F eBox or LIFT4 eBox — not the LIFT3 eBox.

Data cables (eBox ↔ battery)

  • Fischer (5-pin) — current standard (LIFT3 eBox and newer)

  • ODU (8-pin) — older first-generation connector

  • Adapter Data Cable — Fischer to ODU bridges the two if your eBox and battery use different connectors

  • Replacement Data Cable — ODU (8-pin) is a 10.5" cable for older setups

For connector troubleshooting, see Data cable issues. For failure symptoms and diagnosis, see eBox failure.
