    I had posted a while back about my new battery company- Antigravity Batteries http://antigravitybatteries.com

    Everything has been going very well, and thanks to those who purchased during the initial opening of the store.

    Since that time I have been busy developing a new design of the battery. I am posting up to show an example of our latest batteries... We now offer the first terminal style lightweight battery with tool-less connections points. It is our design and first of its kind. It makes for the cleanest and most compact battery yet. It eliminates the hard-wired cables coming out of the battery and cleans up the overall design of these types of batteries, and allows for the most space saving possible. Additionally we are now offering the first "water-proof" lightweight battery for those of you that doing more extreme riding or have watercraft. The Marine/Adventure battery won't be in full production until the first weeks of December though we have some available... Visit the website for more photos and details...http://antigravitybatteries.com

    I"m offering a 10% discount off the batteries for Adventure Forum members. The coupon code at check out is "adventure" .... The 10% turns out to be a better value than free shipping (in the U.S.) and I ship Priority Mail and it takes 2-3 days to get to you if your in the states.


    Below is a picture of the Antigravity 4600 next to the stock Ducati Hypermotard battery which is typical of the 1000-1200 Ducatis batteries about a 7.5 pound weight reduction overall... it would take thousands of dollars in carbon fiber to get that weight reduction.

    How are the A123 batteries connected to one another? Are the simply soldered or are the actually flash welded?

    This is a good question... people should be concerned about the quality of the battery pack build...

    No soldering of the tabs... its not good for the battery. We Spot Weld (also called Pulse Weld) the battery tabs. But we also go further by adding more spot welds than the other companies. The reason is because motorcycle vibrate a lot and having only 4-6 spot welds doesn't do the job for a good solid bond. We use a minimum of 8 and 10-12 on the high stress areas like where the terminals are.

    Additionally you will find other battery companies like Full Spectrum and Speed Cell use a plastic tray which has metal tabs inside it and they sandwich the battery cells between these two plastic parts... so the tabs are just touching the battery with pressure alone...There is no mechanical bond of the tabs to the actually battery. We disagree with this principal especially in electrical applications and motorsports where you need a solid bond that no corrosion or dust can get between. I'm not saying their battery is bad, but rather a build style we don't agree with. Their method allows for much faster production, but is bulkier and we feel batteries need a solid connection rather than just a tab pushing against the battery.

    Sounds great!...I currently have a P310 Odyssey, although I'd like to bring some of that top heavy weight down, and maybe store some seldom used tools there...(2007 G650X for overlanding, daily commute, but sometimes sits unused for weeks...)

    Which battery do you have that can provide the same juice under the same various conditions, and maintain the great reliability of the Odyssey (heated gear...etc...?

    Oh, and Happy Turkey Day! :D

    The Antigravity 4600 (8-cell) is a fine battery for the 650x... It still is very small but has a lot of power. Please keep in mind that the Odyssey will have a longer Amp Hour rating... Amp Hours are the capacity of the battery to store energy. They come into play if you are stuck having to leave emergency lighting on or if you forget and leave your ignitions on... the Oddesey will hold the charge longer. So there is a trade off lightweight vs. Amp Hours... but realistically for what type of riding your do the Amp Hours won't come into play. Also you must remember that the "battery" does not power your heated gear... your alternator does. Your heated gear should only be wired to go on when the bike is running or the ignition is 'ON" this way you can't forget to turn off the switch and drain the battery... The battery only starts the bike... the alternator powers the accessories.. If you read the webpage entitled "Installation Guide" on my site you will get very detailed information about the battery...

    I don't wish to knock any battery maker...I'm sure your Mavrick battery is perfectly fine. .

    Where I feel we have separated ourselves is in the the quality of the build the design, and attention to detail....

    For example our build quality... many welds per tab, Polymide tape and a layer of silicone over the tabs (since Oct). Also our new "Terminal" Style design...Additionally our shrink wrap is significantly nicer than others....I've owned a couple of the other brands and the shrink was just not good with ridges and bumps and flaps with a sticker stuck slapped on. Our shrink is tight very clean fit and a full wrap decals on the 4 and 8 cell ( the new product pictures are not up on the website yet)...

    But I like our design the best... We originally did just like Mavrick, Speed Cell and Full Spectrum with the Quick Disconnect terminals hard-wired with cables directly to the battery, but that method left much to be desired....Some people didn't want it with the Quick Disconnect since it was a lot of extra wire, it was a bulkier design since the cables went under the shrink wrap and were lumpy and didn't allow for easy fitting in a bike like the Ducati Streetfighter or some others that have a super tight battery tray..

    So we knew from our own experience these were valid issues and went to work on a better design. We came up with doing terminals with Tool- less connection points...It took care of all the issues... It makes for a standard type hook up for the battery. It makes for quick connect and disconnect with out needing tools for the terminals. It makes for the most compact design since there are no extra cables coming out of the battery, and it make for a much cleaner, more compact design over all that shrink wraps extremely nicely since the battery doesn't have cables coming out of it.

    But in addition to that our new terminal design allow for a Quick Disconnect Harness to be "bolted on" if someone wants that design...So its the best of both worlds... Your not "stuck" with one style design.

    And last we are the first to make a Water-proof Marine/Adventure Lightweight Battery for use in Watercraft or for use in bikes that see hard core riding conditions such river crossings and so on. So we are actively trying to build new designs that can work for all areas of motorsports.

    Sorry for the long ramble, but I proud of what we are doing and that we are actually pushing to make a better product.

    I think your battery looks cool, but I'd be worried about the issue of vibration and wing-nut terminals. I'm in Utah, ride motorcycles, snowmobiles and waverunners and a lot of my boating friends won't use those for battery terminals anymore.

    I'd be afraid of them possibly vibrating loose and also overtightening and possibly breaking the caps to make sure they don't. Also, how do you mount them on top the battery cells to make them strong?

    West Marine even put out a notice about them here:

    Here's the part I don't understand:

    As you can imagine based on the prevalent bike(s) on this site, most of them are overdone. Over capacity, over designed, over over over. That would make it seem to me that the most popular battery for an assembler of your type would be the largest one you make.

    That said, pretty much all of you build your most attractive battery (from an electrical perspective) in a form factor that won't fit a motorcycle's battery box. 4" x 4" x 4.5"? That's too thick to slide into any of these boxes. You know that, right?

    If so, there must be some really good reason for avoiding a solution to the obvious problem. What is it?

    The battery one size down from your largest would work for the zillion 1200cc bikes on this site but it's not recommended for 1600cc bikes even under ideal conditions which means there's really no safety factor built into that battery (for this application) in that conditions may often be less than ideal... or cooler temps... or too many accessories, etc. Why don't any of you look at the general sizes of battery boxes on these bikes and build one to fit all or most of them?

    The West Marine article is referring to boats and outboard motors... as they state

    ----- we recommend replacing wing nuts with nylock nuts or hex nuts and lock washers that are tightened to at least 10 foot pounds of torque. ------

    I think they are talking about clamp type terminal but I don't know... These plastic "Ts" can handle about 15 lbs of torque, it isn't some cheesy piece of plastic. We've tested it well enough for us to believe in it. We are quite satisfied with it's performance. The screw thread is 1/4"-20 and I have screws that anyone could use in place of the T-screw... but why? I would not torque the screw any harder than the "t-screw" We use the non T screws for when someone buys the optional Quick Disconnect harness and they fit under the Terminal covers... The T screw is great for convenience it works great.

    As far as riding a lot and the vibration loosening the T-screw... I've tested it on the roadrace tracks, and dirt many times with no ill effects or loosening. But then again I do track days a lot and keep my bikes maintained. I have an Aprilia SXV 550, a Hypermotard, and a WR450 and have yet to have an issue. Plus all the other who have bought them...

    Additionally if a rider was concerned that they are riding/racing and a bolt vibrating loose I would expect they would take precautionary action themselves... with maybe putting a lock nut under the wing nut, or zip tying the ears of the wing nut so they cannot come loose or using safety wire if they are careful to on do the ears only and not let the wire hit both terminals... I've yet to see a problem...

    I'm not understanding really...there are many different size battery trays, and I certainly don't know them all but the way we manufacture our 16 cell fits...see the pic below. I am actually the only lightweight maker where the terminals are not on the tab sides of the battery... meaning our batteries fit the narrow and tall profile of most the battery trays...but of course it is more compact.

    The tightest battery box I"ve seen to date is the Ducati Street Fighter which has a box in its rear tail section is a very tight fit for the stock battery....
    My largest the 16 cell fits into this area... see the example below... My battery is a little lower than the Duc battery, and about 1/2" less on each side and equally as wide as the Duc battery... and it can be placed in any orientation without harm... Also if I still made them like the other companies it would not fit in the tight battery trays... My terminals are actaully on the side of the battery cells which allow for my batteries to stand tall and thin like most motorcycle batteris. The other manufactures don't do this.

    As far as making it fit all battery trays... this is extremely expensive... just the tooling for one plastic battery case to fit one of the battery sizes is about $8000 dollars. Also the size of the cells dictates the layout to retain the 12volts in a series/parallel layout.

    The objective from my perspective is as a lightweight handling enhancing battery, not a direct replacement for a SLA (sealed lead acid) battery. There will be compromises... less Amp Hours, not a perfect fit for a certain battery tray.. But the benefits, for those who seek them, outweigh the negatives...huge weightloss for the dollar spent, definate handling improvement, very good power.

    LEt me know if I understood you correctly, and what bike battery trays you are talking about...

    Maybe some of the other guys can chime in as to what their bike / tray size / interest level is. Myself, I'd love to have a light weight compact battery and have been watching these threads. I have several bikes in the stable but just to pick one, let's use my 2006 BMW HP2 Enduro as an example. I'm guessing that it probably has a tray size similar to the 12GS or others of it's ilk.

    Somewhere around max battery size would be a Yuasa YTZ14ZS which according to the specs is 6 x 3 7/16 x 4 3/8. You fit with room to spare in two of those dimensions but the third tosses you right out and when you consider that the bigger dual sport bikes are going to occasionally be ridden two up, heated gear, a GPS and other electronic loads, cooler temps, yada yada yada, there's a definite incentive to get a battery with some head space so you don't wind up paying two or three times as much for a battery that actually either isn't big enough or won't fit.

    Hey Legion... still not following you... my largest non custom 12v is the 16cell... The dimensions is 4" (wide) x 5" (tall) x 2 3/4" (depth) that fits easily in every measurement you propose on the 6" x 3 7/16" x 4 3/8". And if someone chose to not use the T screws you could lose another 1/2 inch in height measurement ... Maybe I'm missing something.

    You also mention electrical loads on the battery such as GPS, heated gear, and other accesories... These ARE NOT items that run off the battery.... The battery on a bike is set up to only start the bike... Once started the bikes alternator will take over powering all the accessories and be providing energy to charge the battery.... Additionally the GPS should be being charged while the bike is running so it own battery can power it while the bike is off. The problem is not with the Battery when using so many accessories... it is with the Alternator not having enough output to power all these items and still charge the battery... A rider who rides with all the heated gear and many accesories should first be finding the Alternator peak output which is available in the owner manual... then determine the number of watts all these accessories draw and have the calculations done to determine if there is enough output to still charge the battery after powering all these accessories and have some head room... I don't know about the GS models which may have a larger alternator...I'm speaking broadly but the principle holds true across the board.

    Anti G; your answer to legion is vague, and being that you don't understand the specific needs of a 1200GS has lead him to ask questions, which I am reasonably certain can be answered by an individual that has researched the model of bike specifically mentioned. Can you please give us empirical evidence that one of your batteries meets at least the stock specification of a given motorcycle? If you can than sales would be guaranteed.:deal

    Well damn Legion, I apologize for the goose chase. I did not update the webpage to reflect the new design measurements. Its been corrected now.

    I'm putting some additional info in my next post that a site member and GS owner named John Ha did a month or so ago.

    Here's some pictures of a 16 cell for clarity...
