Charly Electric scooter

[ElectricJack2250]

Hello everyone, I'd like a little help with my Charly Electric scooter. A friend of mine gave me the scooter but the battery connector seems a little odd. Both connectors seem to have the same color. Both have a reddish orange color. It's not the black and red for negative and positive terminal. I'm wondering which one is negative or positive. Is anybody familiar with the Charly electric scooter? This is the one made in Germany. The friend who gave it to me is also not familiar with the connectors. Any help would be appreciated...

I'm attaching a photo of the battery terminal for reference..

those are very well made scooters made in East Germany by MZ.
my friend gave me one.

wish it has frt susp.



you should be able to tell + and - by tracking those wires to the controller,

they are meant to have four 12v batteries, 24v 24ah

but you can run 2 batteries (24v 12ah) if you want.

my scooter's controller was not working when i got it.
i just used another brush controller off another scooter.

EDIT: You can ignore my post below; Sk8norcal replied while I was typing it up.


Those look like "fast-on" connectors commonly used on small SLA (lead acid) batteries.

Unfortunatley with no color coding or other markings, you'll have to use your multimeter or continuity checker to find which wire goes to the negative of the rest of the electronics on there.

If nothing is marked as to negative, you may have to open up the controller's box to find the largest capacitors (finger-thickness round cans) in it, which will have a - sign for the negative, usually with a stripe down that side as well. Whichever of those two wires has essentially zero resistance or measures continuity to that negative side of the capacitors is the battery negative, and the other will be battery positive.

Most of those scooters take two "12V" SLA batteries, either 7Ah or 12Ah (you can figure out which one by the size of the battery compartment). So the battery negative fast-on will go to the negative of one of those, and the battery postiive fast-on will go to the positive of the other, and you'll need to make up or buy another wire to connect between the remaining terminal on one battery to the other battery's remaining terminal, if that wire isn't laying in the battery tray.

Thank you so much for the replies. I will use the info you guys have given me. Thanks also for posting a photo of the battery pack with the battery connectors connected. It looks like the brighter colored battery terminal is positive and the dull colored terminal is negative. I will trace the wires to the controller though to make sure the polarity is correct. By the way, do you guys happen to know if the controller have polarity protection? If I still end up reversing the battery terminals, will I blow the controller?

yes. do not proceed until you have a voltmeter and can verify the polarity before connecting it to the controller.

Okay. Thank you.

if you have the original controller box, it should be obvious where the plugs go.
