Hi all,
I have a few questions and had been searching for answers in the internet and in this forum in particular, but I'm still not able to get any answer. I've written to sellers in Aliexpress too but till date there is no response.
My question are :
1) I have a ignition switch cum voltmeter, similar to the one listed in Aliexpress, shown in photo 1. The wiring instructions (photo 2) are : green wire to battery's positive terminal, black to battery's negative terminal and red wire to ignition wire. So far so good. However, I'm going to get a new controller which has a 2-terminal ignition switch. See photos 3 and 4. It has a red and purple wire. Can I just treat the red wire and as the ignition wire and ignore the purple wire? Means I leave the purple wire unconnected? I can try it but I'm just worry it might burn my controller or ignition switch or voltmeter.
2) There is a wire (in fact it is a bunch of 6 wires) coming out of the controller labeled as Cycle Analyst. See photos 3 and 4. I presume it is for a cyclometer and I don't have one. Can I just leave the wires unconnected? Will my controller able to work with no connection to a Cycle Analyst? I know it probably will work but I just worry because I had a bad experience with another controller which has a connection to a display unit and without a display unit, the controller just didn't power up!
3) This will be a difficult question to answer but I'll still try to ask. I know battery voltage dictates top speed and controller's maximum current dictates power (how well the motor can accelerate and climb hills), but is there a rough guide on how many volts (of battery) and how many watts (of controller) one can attain top speeds of how many kph or mph on flat roads? I know all these depend on many factors such as weight, headwinds/tailwinds, weather, conditions of roads etc, but I just need estimates. Currently I have a 48V, 20Ah battery.
One more last thing, I read that the power rating of motor does not really matter, so we can pretty much connect controllers of any power ratings to motors of any power ratings? Is it true?
Thank you in advance!
Have a nice evening.
It is 7.48 am here in Singapore. :wink:
