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
