HALLOMOTOR36V 48V 1500W 45A Brushless DC Sine Wave Controller + 36V 48V LCD Control Panel + Twist Throttle +Brake Lever+PAS + Speed Sensor

Replacement and upgrade for a broken voilamart controller. This puts out more power, enough to notice it from standing start and it's a bit quieter and smoother due to the sine wave upgrade.Once you have the wiring diagram you will figure it out. It has a plug for immobilizer and it comes immobilized so you have to remove that pink jumper wire or the display won't turn on. It also comes with a blue jumper wire that prevents you from changing the program settings, so you have remove that before you can program it. It included instructions for the KT LCD3 display but you can also watch YT videos on it. I took it for a quick spin am just finishing setting it up now. Good price for what you get.EDIT: the only issue I have with this controller is the throttle lag. There is no lag if stopped but the faster you are going the longer it takes for the voltage signal to build up to the current speed which creates a lag when you give it throttle at speed. There are lots of posts on different ebikes that have this same problem. It is the way the controller is designed. It takes more advanced programming to have both smooth low speed operation and immediate high speed torque. Basic kits use a different kind of throttle control that makes start up a bit jerky but gives you instant torque at any speed. More powerful controllers can't use that method as it would be too jerky at start up. People have used diy arduino modules to intercept and modify the throttle signal for custom tuning to make it better. And the Cycle Analyst also can do this but is expensive and complicated. So as it is you can't do rolling wheelies or lift the front end for a log while moving. You will be over the obstacle before the throttle kicks in. On the road a half second or second delay doesn't matter, it comes on nice an smooth and is fine but it is a bummer on a mountain bike. If anyone knows of a cheap solution, please reply. Or a cheap controller that has better throttle control. I can live with it but it takes half the fun out of riding my e-mountain bike.

This is a great product. I upgraded my 48V 1000W based ebike with this 48V 1500W kit. With this KT controller, my trike accelerates much faster, and the motor now runs quiet. The kit is very complete, even includes the a connector block for the motor phase wires, and the battery power connector pair. The included LCD3 display panel has many features and adjustments. Ask the seller for the controller documentation. I didn't ask for, but found the LCD3 documentation with a quick google search. The controller accessories were plug compatible with my older components (PAS, brakes, throttle).
