Works
Seems to be working as intended. I ran into an issue where my led display on my throttle was staying illuminated even with my key removed. This throttle has been operating perfect with other modules of the same brand. Took a second to spot it, someone at the factory flipped the leads on the "power locks" (blue+red wire plug) once swapping leads in this plug the led screen turns off with key now. I read a few questions and reviews with this same issue. That's the fix. 😎👍🏻

Very poor technical support
This unit was DOA. After lots of testing and comparing connections with the old controller, I had to reach out to the seller for support. Their response was to ask for a photo of the connections. That was the extent of their “support”. I do not trust that this controller will be reliable for those that have had success out of the box.

No response when connected
I’ve connected all wires appropriately and even purchased a 2nd throttle with key start and nothing. I get voltage to throttle but no response to either motors I’ve connected too. Explanation or I’m returning

Controller di velocità, perfettamente compatibile e montata in pochi minuti
Controller di velocità, l'ho montato in pochi minuti su un kart elettrico alimentato in corrente continua a 48 Volt, senza alcun tipo di problema di compatibilità con gli altri accessori, come ad esempio il pedale dell'acceleratore già presente sul kart. Utilizzato per qualche ora, non ha dato finora alcun tipo di problema. Approvato.

Gato por liebre
Compré el controlador WOOSTAR 48v 1000w hace 2 días. Lo monté para probarlo con sus respectivos fusibles y conexiones (faston). Se apaga cada unos pocos metros, se calientan los cables de alimentación del motor (azúl y amarillo), son todas las piezas nuevas. "Acelerador, llave de contacto, motor, sensores de frenado". Pd: no me llego el de la imagen de color negro.
