I'm no expert, but it seems like the obvious solution to the problem of limited space. With a little 12v battery, it doesn't really matter if you produce no electricity at stop lights. 12v motors are cheap and it shouldn't be too hard to mount it to something like the arch chain tensioner.
Hi. It can charge a 12volt motorcycle battery, but a small one. I have the charging coil system in my bikes, but if you want the best use of the battery, I would advise you to use low voltage LED bulbs. I have the full kit of lighting, indicators, break lights driving lights, main and dip beam, ALL on my motorised bicycles, the batteries I bought are 6volt for one bike, and 12 volts for another, the amp hours is crucial for longer charge, being kept, the more amp hours the battery, the easier, and easier, and longer, the battery lasts.hello to all. i have a 80 cc china motor on a huffy frame. this is my
thing i want to do to it and ask for any feed back you all might have.
i want to use a 12 volt motorcycle battery and run a set of led fog lights and a 12 volt red running light on my bike. so any info would be help full.
When you un solder the wire on the generator and are you soldering in two wires leads? "Connect two wires from the coil to the two yellow to the voltage regulator." I have the voltage regulator from Amazon wingmoto rectifier regulator. The wiring instructions tell you to install yellow pink to the lead coming from the coil. Your instructions say to unsolder the wire from the generator and solder in a insulated wire then attach to the two yellow wires on the voltage regulator.Actually the whole 12v charging system is very easy.
You need charging coil that is NOT grounded at one end. It looks like the one offered by Gasbike is the easiest to modify:

See where it's soldered on the top end? Unsolder it and attach an insulated wire and run it outside the case with the other wire. Then attach it to a cheap 4-pin moped/motorcycle rectifier/regulator like this $4 one for a GY6 moped:

The two wires off the coil are the yellow wires, and the red goes to the battery + and green to battery - (ground).
For a battery you can use a small lead acid. Gel cells that are 12V 4Ah are very popular for alarm system back up and generally cheap. Hell, that's probably overkill and the 1.2Ah battery posted by Stoltzee will probably be enough.
But that's it! Alternator coil, rectifier/regulator, battery, you're good to go! The worst part is finding a connector for the regulator. In that case you can use a different model with a wire pigtail like this one for $9:

If you use the Yamaha regulator you wire the coil to white and yellow, red to battery +, and black to ground. Add a toggle switch between the battery and regulator and you're done.
Edited to add:
Here's a good candidate. It's your standard single phase 4-wire rectifier/regulator, comes with a pigtail wiring so you can easily connect to it, and best of all, it's cheap!!

And finally, if you don't feel like modifying the Gasbike charging coil, you might be able to use a Briggs & Stratton voltage regulator from their old 5 to 9 amp "Tri-Circuit" system that used a 1-wire stator coil.

Connect the yellow wire to the charging coil wire, and the red wire to your battery/lights. Use the center hole to make sure the regulator is well grounded to the frame. The down side is you're actually throwing away half of the charger's output, but it will work without modifying the coil wiring. It's the difference between a half wave and full wave rectifier.
Good luck getting any sort of answer from @CroMagnum...lol...Last seen Dec 26, 2017.
Lol archeological
Nice to have ya back...During my long sojourn upon this earth, I use to live near you in Little Compton as well as Barrington, not far from where you are at...I was still young then and worked at Benny's on Metacom Ave in Bristol...lol.
Benny's is long gone and greatly missed, where are you now?
I am now retired these last 12 years now and moved right after I retired from the seacoast area of New Hampshire to Alamogordo New Mexico...It costs a third of what it cost in New England to live here...Ya get to glow in the dark too...lol...This was the place the first atom bomb was tested in 1945 before Hiroshima and Nagasaki were bombed...lol.
