Common electric scooter, bike, and go kart speed controllers use a 1-4 Volt DC input signal to control the motors speed. It does not matter where the input signal comes from as long as it is a 1-4 Volt signal. Most throttles have a 0.8-4.3 Volt output signal just to be on the safe side.
Wiring a single throttle to work with two speed controllers is a very simple and straightforward procedure. All you need to do is wire the throttles + 5V DC input power wire (red) and ground wire (black) to one speed controller, and then wire the throttles output signal (usually green or white) to both controllers. This method will also work with more than two speed controllers.
One battery pack can supply two controllers. The battery charger can either connect directly to the battery pack or it can connect to one of the controllers if the controller has a 'charger in' connector. Here are two illustrations showing how to wire everything together.

hi. friends i need battery 2500w or 5000w ?
Hello everyone, some time ago I started experimenting with my E300 razor :)
first, the throttle with overvolted kit to 36v, and lithium batteries, the improvement was notorious, but it was still not fast enough for me (hehe) so I got a 36v 800w motor and a controller for that motor.
a couple of weeks ago, and after seeing that it had already been experienced on the internet, I decided to mount more batteries, a second motor and controller (36v 800W), try to connect both as figure the scheme but I can not make both ... some kind of help ?? Thank you
