【Peak 120A Automatic Overcurrent Protection】Max peak current: 120A; Max continuous operating current: 65A.When overcurrent occurs, the controller automatically reduces the PWM output. No‑need to frequently replace fuses. Voltage range: 13‑77.5V.

【Built‑in Fan, Electronic Braking & Fault Indicator LED】Comes with built‑in cooling fan; no extra cooling parts required. It adopts half‑bridge drive mode with electronic braking. Onboard fault indicator LED allows quick troubleshooting.

【Variable‑Speed Control】Compatible with variable‑speed pedal. Maximum speed limit can be set in this mode for safe top speed on kids’ ride‑on vehicles. The pedal ramp‑up time setting prevents sudden jolts caused by hard throttle presses.

【0‑30 Second Adjustable Soft Start / Soft Stop】Reduces inrush starting current to extend motor service life and improve driving safety when upgrading kids’ electric ride‑on cars.

【Adjustable Low‑Voltage Battery Detection】Built‑in battery voltage monitoring prevents deep battery discharge and cell damage. The unit will shut down automatically when voltage drops below your preset threshold.

【Settings Reset Function】Quickly restore factory default settings if parameters are changed incorrectly by accident.

【Overcurrent Protection (Enable / Disable Optional)】Equipped with 4‑channel PWM power MOSFETs plus freewheeling diodes for generous current margin, suitable for complex operating conditions. This optional feature meets different racing‑scene requirements.

【Pre‑Drilled Mounting Holes】Aluminum alloy sturdy housing. You can fasten it directly with screws without extra fixing accessories.
