6v and 12v HT Generators?

Mini Gens

Hey I recently purchased a 12v magneto and 12v mini generator from this company and they work GREAT!!!! You know the 2 stroke comes with a 6v magneto. Now I'm running head and rear lights; signal mirrors; and a 1000w sound system on a 26" motorized bike. Told me i was crazy now they want me to built them one. I have a chrome Micargi stretch beach cruiser 55" wheelbase. A 250cc is going on that bad boy. With the Mini battery charger( purchased from same company) my 12v 35ah sealed battery is always ready to go. I love going to the parks here in Florida and watch a movie on my7" flip out screen am/fm/cd/dvd player powered but the battery people just freak that all this can be on a bicycle

I've found an inexpensive headlight (12V, 35 Watts) that I would love to place on my motorbike. But I don't think these little coils can crank out 3 amps. I guess if you place a 12V battery and charger in the system, you've found the Holy Grail.

Just a quick question. Has anyone tried using the friction generators, which power head and tail lights, and to trickle charge a SLA battery? I know the friction generators steal some of the power from the motor but it seems like it could be a quick, low hassle solution for those who need headlights or taillights.

I wanna know if anyone have tried to get a generator or alternator to charge a 36 or 40 volt battery as in an electric motor mounted on a bicycle?

I bought a 12v mini gen on e-bay for 30.00. Had to do a little clearancing so nothing touched anything and grounded out. After installing, I noticed a decrease in motor HP. Nothing is connected to the gen yet. I'm building a rectify/regulator to charge an 8.4v ni-ion battery pack for a Solar Storm 10000lm led head lamp. Just wondering if the mini-gen windings could be putting enough drag on the magnet to notice the power loss? (With nothing hooked up yet)???
If so, some mods are going to be nessesary to reclaim the lost power.
Any comments or suggestions would be greatly appreciated. Thanks.

Did you buy yours from GasBikeDotNet on Ebay http://www.ebay.com/itm/262277794979?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT ? I bought one of there's and put it in my motor today waiting on other parts for my lighting to come in.

What v did you get? And I believe that it was GB.Net, it's been a while. They sell a reg/rect. Box for the mini gen. I like to build my own. Just getting all the electronic components from China is what's taking all the time. All just for the fun of hobby(s).

I got a good steady 6v to 8v at idle and 16v at a quick crack of the throttle. I am doing the same thing waiting on parts from China. While I am waiting I got this bright ideal I have this rectifier so I plugged it in to test my forward voltage drop and amps I got a drop of 1v but when I tested amps I dont know what happened the motor started ramping (1.1 Amps ) I shut the motor off . I then got another bright ideal I had an old smart phone charger I figured well I know this is rectified and smoothed ( lets plug this in and see if I get the constant voltage ) I got nothing but 0.3v. I removed it and tested the gen again alone and I only get 3v output now. I am not a smart guy when it comes to this Electrical stuff.

Can anyone tell me the capacitors I should use with a rectifier?

Ok I have done some testing and I think I know how to get good clean power from my Gen. As we all know that the Gens and CDI puts off AC and that the wave form is crazy cause of the magnet spinning at diffrent RPM. Well when I take my DVM and I plug into my Gen and the + side of Ignition coil hot side I get a steady 5.08v at Idle (I mean like super steady no voltage float at all) So my thought is this. Take my Rectifier and plug the ac lines into the Coil and my Gen and then see what I get and what happens and the Voltage is and also if we gain power back or loose more power from the wheel. I did note that the bike dont really feel the same with the Gen as far as power goes but there is always a down fall somewhere
