LP, Did you block off he pair valve when u installed the a/f as it will give false readings?

This is modded gy6 stuff. All the GET is gone. I was talking to spazrer12 about this. Once your bike gets so crazy you are out in custom-land. You gotta build stuff for it, all the bolt on stuff works no mo

Other stuff. New lith ion battery and a lith ion charger. Don’t ever use a regular tender on lith ion if it’s not designed for a lith ion (and they aren’t). You’ll fuck it up. keep rubbing it in. $100 booboo |

You’ll fuck it up. keep rubbing it in. $100 booboo I did the same. Those batteries are pretty tough, and once the sink below 9v the chargers see them as dead and they won’t charge. There is one charger out there that has a “resurrection” algorithm that’ll bring them back from under 9v but it’s expensive for a condition that shouldn’t happen if you take care of them. |

You can use a regular tender in a pinch, charge it up and take it off, but don’t leave it on all winter or even for days.

Had to move to unleaded from leaded race fuel so I wouldn’t burn up the sensor. With leaded that sensor will last about 20 minutes. But I miss the smell of race gas. I don’t miss having to take it back to the house to refuel. I kinda like just popping into a gas station. But don’t get me wrong, there is a difference in power between 93 octane and 110. |

Went for a 2 hour ride today and on the way home the bike surged and I know that surge, I’d blown the regulator/rectifier. So I was sending a shitload of voltage to my lith ion battery. Should have pulled over right then but I was so close to home I thought I could make it. I thought wrong. The battery over charged and I could hear a sizzle and then smoke. I pulled over, pushed the bike across a small field to a bicycle shop and asked to borrow tools and a fire extinguisher. My battery was in meltdown mode.  A lot of that junk is from the fire extinguisher Battery when removed  And the bike when cleaned up a little  Still inspecting damage, but I think I’ll need a new battery, rectifier and harness (this one is fried). I’ll get a new strator too. The bug is in the strator overloading the rectifier, which could be any number or reasons. Still trouble shooting that. But with new parts hopefully that won’t happen . I think something was kinked in the harness and at high voltages it arc jumped to short. But that harness is dead now so I’m not going to figure it out. It wasn’t a wreck just an unfortunate breakdown. She’s back on the operating table and I’ll have this sorted quick fast. Any thoughts? |

*sigh* Back on the operating table again  |

Nice build.
Sucks that you had to learn the hard way with the battery. Although Lithium Ion is future, scooter charging systems are not smart enough to deal with the new battery technology.

Yeah, lithium batts are very particular about charge rate. Make sure you clean the extinguisher residue well, it is corrosive.

Can you install a fuse/ breaker? To prevent the juice from frying your battery.

I thought about a fuse. But there is one already there.
The issue is that the rectifier is blowing out. I know plenty of people that run these batteries in Ruck swaps with no problem. I ran one before.
But if the regulator goes, then it sends massive voltage to the battery and you see what happens. Technically the rectifier should be protecting the battery. No regulator would also fry a regular battery.
Dunno though. Gonna make some calls today and get the parts sorted out. Make double sure all this will work. If it is the battery, the I got a good old fashioned one to replace it with.

Sucks about the battery, but glad it wasn’t worse - Li-on batteries can do some damage.
As for rectifier/charging, is there a Li-on specific one out there? Seem like you’d want some specific circuitry for that application.
