I already posted this on the other forum, but I figured it wouldn't hurt to get some opinions here as well: So I was at my local gadget store yesterday and something caught my eye. I know Brent has done a battery upgrade from 4ah to 6ah, but the battery he chose retails for around $60. I found a 9ah 12v battery for $19.50. It's too long to fit in the stock battery compartment, but I can either cut away some plastic to make it fit, or I can just keep the stock battery and relocate the 9ah under the seat. Total cost would be around $20 and I would be left with 9ah + 4ah for a total of 13ah. Do you guys think this is a good idea? heres a picture of the battery in question:  |

I'd just look for the 7ah that fits in the stock location. It's more trouble than it's worth IMO to add a 2nd battery. More unnecessary weight too. I'm starting an engine with compression as high as I can seem to push without retarding timing or running above 93 octane fuel with roughly 30 more cc that likes to wear starters out and I have no trouble with my 7l-bs. 49ccscoot.com/bigbatts.html |

I rewired pretty much everything electrical on my scooter to run through the battery, rather than the rectifier and stator. So my battery likes to die alot. I could rewire it yet again to run off of this secondary battery, and run a onboard float charger that I could plug in everytime I come home to keep the secondary battery charged, and use the main battery just for starting purposes. That would really save me some stress when I'm out and about, hoping that my scooter will start back up in the parking lot. Kick start is useless on cold days for me. On a side note, I just finished installing a wireless brake light system that attaches to the back of the helmet. It's awesome! www.webbikeworld.com/r2/riderlight/ |

Nice brake light.
I gotta ask, why don;t you want to run things off the charging/lighting circuit?

Nice brake light. I gotta ask, why don;t you want to run things off the charging/lighting circuit? I think I have a wiring issue. When I first got the scooter it had a blown headlight. I replaced it and went out for a ride and it instantly blew the headlight again, both beams. I measured the voltage and it was putting out almost 40V AC, on a 12V DC bulb. Swapping one wire changed the entire lighting system over to run off the battery, at 14V DC (while running) I haven't had a single anything blow. |

Did you try a new rectifier? I really don't know much about electrical stuff but I have seen a resistor on some 4 stroke scooters that I believe is for the lighting. Like this: blacktopmotorsport.com/scooter-resistor-5w-5ohm.aspx Does your 2 stroke have anything like it? If so, maybe it went bad? |

Yep thats exactly what mine used to do. After I replaced my rectifier my headlight bulb has lasted for about 5 to 6 months. Before it would only last a few days or a week. The rectifier wasn't keeping things at 12 volts at high rpm's so I was constantly blowing bulbs.

The rectifier wasn't keeping things at 12 volts at high rpm's so I was constantly blowing bulbs. Thats the thing though, on my scooter the headlight was wired directly to the stator, so it was getting AC power, instead of regulated DC. Don't ask me why they decided to wire it that way. |

Oh! That is messed up! Thats some funky Chinese wiring.
