Motobecane CDI + Battery + Rectifier for really bright lights

ℊRashid 7☀☥ /

OK Folks

Moby 40S build.

le partie CDI, I would like to add maybe a 4 cell Ballistic 12V battery or something small enough to fit under the seat post mount to possibly keep some H4 or 9005 shining at a constant rate along with a rear LED (12V 0.8W).

What would be the best low cost option to do this? I'm sure the stock regulator wouldn't work well, so maybe a gy6 rectifier (to keep the LED from blowing) or even the one treats sell would work

Any installation tips?

PEACE

A battery is only a accumulator (electrical storage), if you want to run 65 watts of lighting you need a genny capable of putting out same wattage with or without a battery.

im not an expert, but i think GY6 regulators are half wave. i would float the ground off the stator and than rectify and regulate using a full wave rectifier/regulator. this way you take advantage of the full AC wave form. the whole bike would then have to run on DC. i have a diagram of my basic system

Just for fun, that's what my electricals ended up looking on pug. Didn't include the CDI and rectifier itself, the three inputs are wire from CDI, wire to HT coil and 12v+ stabilized from trail tech rectifier.

I know this is an old thread but, its possible to use the trail tech vapor as a rectifier for the whole system?

Trying to decipher that diagram. Holy batman. Does look like its possible.(edited)

Re: Motobecane CDI + Battery + Rectifier for really bright lights

No, you still need the trailtech rectifier from the yellow wire.(edited)

Oh. Interesting. I know the trail tech takes ac or dc. Okay I’ll look into it. Nice to know they offer one.

I have done this with a vapor and can confirm the rectifier is the way to go.

The Vapor rectifiers are $$$$$$

Kubik,

Great diagram but the most important part is whats not shown. I see your DC voltage source but can you show how you connected the Trail Tech in order to achieve that source?

Thanks
