hi there,

i was wondering how i can install electronic accessories on my e-bike.

i want to connect an amplifier that can work on 24v/36v/48v.

i was wondering where i should connect the red (+) and black (-) power cables. to the controller?

should i add some special connector to this wire like "Anderson" connector?

will t be different connection with each e-bike model? or battery model/design?

thanks

You really want to plug these sort of things directly onto the battery. The controller is there to control the motor.
If you have an amp that runs on 12v you could use a DC to DC converter to drop the 24v/36v/48v down to 12v. Just make sure the converter can handle the power draw of the amp. Eg if the amp draws 2A, then use a 3A converter.

thanks Delphinus!

the thing is this:

i want to develop and sell sound systems for 24v/36v/48v electric bikes and electric scooters.

my amplifier will already have the converter in it so it can work on the currents mentioned.

now, it is super important to me that the system will be DIY, so any one can install it and won't have to go to a professional to install the unit.

the only challenge is connecting the power cables to the battery (or to the controller..?). as for now the system comes with red (+) wire with 3A fuse on it and black (-) wire.

do you think it is right to sell it this way to all e-bikes and e-scooters types? should i add certain connectors?

thanks

Because connectors will differ between different bike systems your DIY'ers might have to do some modification. There is no real standard AFAIK.
You really want to tap in between the battery output and before that feeds to the controller. I wouldn't get caught up with plugging into the controller. Just think about the battery as that is your source of power. Therefore you want to connect to that somehow. The plug types will vary depending on the battery and plugs on each individual bike etc.
