Gearhead, are you sure you aren't talking about the speedcell quick disconnect connector? You don't modify your bike at all, the connector is just a quick way to disconnect the battery so you can swap it out in between sessions if you run a total loss setup.

Frog's right. It's just a connect up. I have the Speedcell by Josh. Love the way it doesn't need a trickle charger. |

Thanks guys, the only photos Josh sent me showed his product at an angle that I couldn't make out how connections were made.
Still curious about the EBR connections, though. |

>>>>How are connections made on the EBR battery?
I have detailed photos of the BUELL unit and it is REALLY awesome.
I won't be home until late tomorrow night but if you want to remind me I'd be happy to post them.
The Buell battery has some interesting and impressive research behind it. |

Connecting to the EBR battery is a M8 bolt with a nut on each of the small sides.

The EBR battery has a copper lug on each of the "short" ends. As Jens indicates, attachment is by means of a nut and bolt.
It'll be clear when I get a chance to post a clear photo. |

Didn't get a chance to upload but you can see the lugs on the ends in THIS Erik Buell Racing photo.
The lightweight battery comes with the lugs and the other clip that attaches to the lug. I think you just supply the M8 bolt and nut. |

See if this helps . .

Do either if you guys have a photo of how you mounted the EBR battery in a bike? |

My EBR battery arrived today! It was ordered Saturday, now that's service.
Total weight savings is 9lbs. 3oz. as compared to the stock battery in the bike.
Happy to do my small part to support Erik Buell Racing, too. |

Note on the battery: only a bolt is required, a short 6mm if memory serves, though I might be wrong. The clip is the same nut-clip that holds the plastic 1125R pod covers on, and snaps in place on the terminals. If they didn't come with the battery (perhaps there are supply issues), you can order them at your Buell dealer for less than $1 apiece.
Compared to the SpeedCell, the Buell battery has a balancing board that keeps each cell equally charged. This is a big issue with lithium-ion batteries (go read about proper battery charging on some of the RC plane forums if you want to know more). If you don't have such a board, or the kind of individual cell charging common on RC battery packs, you can fail cells due to overcharging the highest voltage cell, and you are almost certain to have some cells in undercharged condition. This is not an issue with a battery you're willing to throw away after a few months, but the Buell battery is designed to keep the cells in good shape for a multiple years of use. The cell manufacturer estimated the cells should be good for a decade in typical motorcycle duty cycles. |

Might you offer a link for those of us clueless guys? |

Steved,
What should one use to charge the Buell battery? I've heard that a battery Tender should NOT be used.

After recieving my EBR battery I emailed them and asked about charging it. Here's the answer...
Ralph,
They usually have about half a charge as delivered. Optimally charge at 12 volts, 2-3 amps for a couple of hours. It's a 4.4 Amp-hour battery so that should well do it. A 0.5 AH trickle charger will take 8-9 hours. Don't charge above 14.5 volts, and don't charge above 6 amps.
You will find these batteries hold charge really well, and honestly should last many years unless cooked with too high amperage or voltage.
Thank you,
Tech Support

There is a great discussion of lithium-ion pack balancing at: http://www.rcgroups.com/forums/showthread.php?t=59 9287
The only addition I would make to the EBR tech support information above: the ideal charging voltage for the EBR battery is 13.6 to 14.0 volts, and ideally about 2 amps. Most motorcycle battery chargers will give you something like that voltage. The only real concern with these batteries is excessive voltage and amperage together, which again, will occur under very unusual conditions which would also likely fry a regular lead-acid battery during charging. They are very robust, and you can basically just treat them like a regular battery. Charging is likely never required unless you run them completely flat; they'll start a 1125R with the charge in them as delivered at normal temperatures, and will fully charge from the bike's electrical system in the first hour or so of riding.
Again, as EBR has pointed out, performance of lithium-ion batteries falls more quickly than lead-acid with temperature, and this battery is not ideal for starting a 1125R at temperatures below 35F. Conversely, it has very different characteristics than lead acid. It'll get stronger after each start attempt in cold weather as the cells self heat, rather than a do-or-die on the first attempt as with lead acids. The starting amperage requirement on the 1125R is one of the highest in motorcycling, and this battery will start any 4-cylinder sport bike superbly even at lower temperatures. |
