Hi All, Has anyone got any info on putting a g/wing battery in my 2000 std Valk? I have done some research on the subject of putting a bigger battery in,but there doesn't seem to be much info. later on when my alt is stuffed,I would like to install an 90amp alt. I tow a camper & was just looking for a bit more power to play with. cheers... Brian.  |

The only issue is the actual battery size, making it fit in the existing battery compartment.

No. Matching the battery capacity to the alternator is an issue. eg. too small battery with higher power alternator will ruin the battery. Too big battery with low power alternator; the battery capacity is wasted. I have been running a GW battery with my compufure alternator for years. The battery gets replaced much more often than it would in a GW as it stops holding charge. It's not exactly matched to the alternator though that's what Compufire sells as a kit.

Been running Goldwing battery in my V65 Saber for years (20+) with no change to the Alternator.
The Goldwing battery last much longer than the original factory sized battery. Usually 1 to 2+ years longer and the longer cranking capacity can be a plus if you are working on it or experiencing starting issues.

Thanks, thats what I was thinking Pete... Was just wondering how to fit a bigger battery as the g/wing battery is a bit higher & wider. Maybe a lithium battery might be the go. cheers... Brian. |

Don't go the other way - too small battery for the alternator and the battery gets boiled and ruined. I ruined a new battery that way.

As Pete posts above, your only problem will be the physical size of the battery. If you can get it in there, then any higher amp/hr capacity can be a plus as you envision. The alternator will not be negatively affected simply because of the larger battery.  Your future higher capacity alternator will not be a problem either regardless of which battery you're using. It'll have a voltage regulator to limit the output capacity to protect the battery. You're on the right track. |

I had to modify the battery case to fit the Goldwing battery, making it wider.
I ended up having to actually cut the end of the case out to get the last 1/8 inch.
And the GW battery is a very close fit, no extra space whatsoever.
I am still running the GW battery today, how is that for a long term test.

My GW GL1500 battery (lithium Iron) is reversed polarity from the Valkyrie. I haven't done it yet, but bought an extra set of ground/positive leads from a Valk, so if I ever but it in the Valkyrie I'll have some leads to revers the polarity.
If it fits in the battery compartment, then you can use it.

Reverse polarity ? In the UK that would be + earth . Do you mean the posts are the other way ? |

If you put a multimeter on your Li-ion battery when your bike is not cranked, what is the reading?  -Mike |

Positive to positive and negative to negative, ALWAYS on the Valk.
Poles can have reversed placement that does not indicate reverse polarity (ie. positive ground).
You may need to turn the battery around or use longer cables or reroute the cables, in my case I did not need to do either.

All I'm saying on battery vs alternator outputs, is my experience is they need to be matched (with a floor on the battery capacity - eg don't go less than a certain level) or you'll get either a ruined battery or less life. I don't have experience with an oversize battery & smaller alternator. Compufire alternator - 90amp - does not match well with a GW battery as I have to replace mine too frequently. Even though that's what they sell as a set. Lithium batteries scare me what with them blowing up in various venues. There was a technical report on why they blow up on TV a couple months back. Very interesting but I don't recall who put it out, and I'm not finding it online. I always charge my Li-Ion batteries when I'm in attendance. Not that that's fail-safe, and they also blow up when not being charged. That's what I see online with vaping device explosions that are captured on security cameras and played on the news. Usually some guy or gal with it exploding in their pocket or purse with injuries. Or hoverboards blowing up in malls or airplane luggage compartments. As for me, I'll stick with older less efficient tech - and safer. Just sayin... Here's a technical video from Professor Jeff Dahn (Dalhousie University): https://www.youtube.com/watch?v=pxP0Cu00sZs |

Me too... and it's not just cheap vape pipes, you see expensive iphones go
off like rockets in people's pockets on tv every now and then...
I've got the one in my 1500, and ones for tools... powerful tools that aren't
connected to an outlet or a gas tank are awesome...

Sorry, I meant reverse posts. That is why I mentioned I bought an extra set of cables, so I could make them longer and reach the opposite side of the battery, if ever needed to mount it in the bike.
I Know everyone is typing Lithium-ion, but mine is a LiFe (Iron) battery. The charged voltage was high 12's. I carry it in my saddle bag. Bulky, but lite.

Lithium Iron Phosphate (LiFePO4) batteries do not blow up unless charged with over 15+ volts, and then just get hot and melt down. Old original Lith battery designs were the ones that blew up https://advrider.com/index.php?threads/motorcycle-batteries-agm-gel-wet-lithium-iron-phosphate-lifepo4.757934/I use this one, BikeMaster Lithium Ion Batteries DLFP-16-BS DLFP-16-BS 3 yr warranty. this size has slightly larger amps than size for valkyrie. GW battery from bikemaster is too big. |

I think the g/wing battery will fit but it needs some big mods to the
battery box.
One of them Lithium batteries might be the go me thinks.
cheers...

LiFePO4 is about 8lbs lighter. top of the line ones provide a 3 yr warranty. |
