Simple wiring questions! Lyen programming! please help!

[omnivore]

So, I am not sure of how many readers witnessed how incapably ignorant I am of battery technology when I was posting some time back about trying to build my own battery. So if you did, you probably had a good laugh and guessed I gave up on trying to build my own. In the end basically; I am inexperienced and it was far too expensive a topic for me to chance making mistakes. So I decided to buy a premade from CONHISMOTOR is Shanghai! WOOT! so around $600 bucks later, I have a very heavy very durable feeling, 48v 20ah li-ion battery sitting in front of me. I also have a Lyen programmable 12 FET 3077 Mark II Controller in front of me. SO ON TO THE QUESTIONS!

RIGHT Picture:
The wiring does not match between my GNG motor and the Lyen Controller, can i just switch the green and black wiring positions and this problem be fixed? does it matter which one i switch *controllers wires or the gng motors wires?* my instincts tell me to switch the position on either one is not going to matter as long as the wiring match to the proper color?

LEFT Picture:
There is a little red wire hanging off the Lyen power cables (red and black) that is labeled (+ignition) that is not on the battery. I am guessing this is strictly to accommodate an optional Key switch ignition? is this correct? can this just be left unplugged and taped to the side of the cables to keep it out of the way or do i need it to have some sort of positive charge through that cable in order to start the bike? Also, if it is true that I can just not use it, do I need to turn it off within the programming of the lyen controller?

which brings me to my last question:
What are good/safe/beginner default programming values for my current configuration within the Lyen controller? is there a way to make it cut off before it goes under or over voltage in order to protect the battery from being discharged too high or low? What are the default values of this controller?

With your help I will have this thing mounted,charged and ready to ride within my spring break here and ill post a build/final product topic before I go back to school!!

THANKS AGAIN GUYS!

You can switch the wires to make like color go to like color and you should be fine. The wires can be pulled from the back of the female connector by going from the inside and pressing the little tabs down and then giving the pins a push. Raise the tab back up and push it back into the right slot and you should be good to go.

I think that wire will need power for the controller to power up. If your kit came with a handlebar switch then you can just have the switch go between that wire and the positive off the battery and it should turn your controller off & on.

I would start with the kit the way it is before you start making changes to the programming. You may find that you like it the way it is and then there will be no need to change settings. There are some LVC settings you can program, but if your battery has a BMS then that is already taken care of.

Good luck.

As StudEbiker said, leave the program alone.
You cannot change the lvc or hvc without loading the stock settings first.

If Lyen has the program with the stock settings in the controller you could change the lvc & hvc without messing up your controller.

But if you are not formilar with the program, leave it alone.

And as said, your battery should take care of that itself.

afair you connect the little red wire to battery positive to power it on. but why not just ask lyen?

gotta love how i ask a (incredibly ignorant but relatively easy for someone more experienced than myself) question about wiring and it is mostly ignored with a few comments (thanks to the few who commented).
...
Am i doing something wrong in my posts? Do i have a bad reputation on this forum? did i just post at a bad time, what?

Question was answered in the first response:

Answered again here:

afair you connect the little red wire to battery positive to power it on.

You need to supply power from the thick red wire on the controller to the thin red wire. This is for a remote key/kill switch and StudEbiker suggested using a handlebar on/off switch for this if you have one - since you don't appear to, just jump the wire over on the controller wiring and don't use the feature.

...It has an power ON and power OFF position on the battery, I believe this is set up to be the ignition. So could i just pull the large red wire and the small red wire back out of the connectors strip them a bit and twist them back together and put them back into the connector for the main large red wire?

No - do not mess with the battery power switch.

...what i am asking is if i can splice the little ignition wire directly to the positive pole coming from the controller beside it, then put that into the connector to connect to the battery? I KNOW it sounds like the same thing that they are saying, but I want to make SURE.

Exactly. Splice together, run to same battery connector.

Yes, the small red wire is also called an ignition wire. Some people wire it to a switch so you can lock your bike on or off. Your controller will not run without battery charge current hooked up to the positive of your battery.

Ed Lyen has a life so doesn't just sit waiting for emails, he works on his own and will get back to you as soon as he can. Like you he as a life away from work.

That small red wire is for ignition, you can permanently connect it to the battery positive for a permanently on system. Connect it through an on/off switch if you want to switch the controller off when not using the bike (one advantage- if you bump the throttle the bike won't fly off- or burn a hole in your carpet like I did- if switched off), you can always disconnect the battery but the chances are you'l get arcing of the contacts and eventual damage if you go that route. Or add a key switch for a little security, others can't just switch your bike on. This switch only carries a small switching level of current, pretty much any switch will do. It seems a sensible easily implemented option, why not make use or it?

Ed Lyen programs suitable values into your controller before sending it, these are likely not to be 'wild' settings unless you asked for it. Use his initial settings unless you have reason not to. He sometimes keeps a screen capture of the settings, he'll send it if he has when asked. One failing of these Infineon based controllers is that the eprom settings can't be read.
You've made a good choice getting a Lyen controller- excellent support.

Did you get a 3 speed switch? If not you'll find your bike may just give 66% power, the default setting 2 is often set to this unless Lyen was aware you needed it set at 100%


Just set things the way you want them just now, you can always change later.

Have fun!

I downloaded driver and program files but when I try to open up "Installer" or "Installer 64 bit" I get a black box with four items "access denied"....anybody have a clue to what I am doing wrong? have windows 7 PM thank you photo of my bike with older controller
