Smallest size battery I can use?

[tkent02]

My KTM came with an AGM battery smaller than that, it spun the heck out of my GS550 starter, and it's only something like $26

That is an ideal size for the customizer, but I know what you mean about the price!

Just something I saw, pertaining mainly to battery longevity-

Cranking is the biggest load. If it's tuned perfectly and always starts at the first touch of the button you can use a tiny battery. Anything goes wrong and you are push starting.

Without doing a lot of analysis on contributing factors that is about it. You only need amp hours if you are cranking a lot. Your smaller battery will actually charge faster providing you with peak cranking performance faster than a larger battery. If you have a series r/r and don't spend a lot of time idling at 1k rpm you will be good with the smaller battery. Just keep charging system in peak performance.

He could just buy the smaller size odyssey, then. Sounds good!

Can report the battery cranks amazingly well ! Instant start no hassles.

Antigravity

That 'Antigravity' looks to be about the same size as my dinosaur battery. Does anyone have any figures on weight savings?

For some reason, I had always assumed that the lithium-ion batteries were much smaller than old style. Guess I'm wrong.

So they mount exactly where the original was, and there's weight, but no space saved?

Technical Details
240 Cranking Amps- (Cranking Amps are the power the battery has)
9Ah (PB Eq) – Amp Hours are the Capacity of a Battery
Dimensions and Weight
USA SIZE (LxWxH) 4.25″ x 2.25″ x 3.75″ (Height is measured to the top of the terminal bolt heads)
USA WEIGHT 1lb 9oz
METRIC SIZE (LxWxH) 110mm x 57mm x 95mm (Height is measured to the top of the terminal bolt heads)

The space saving comes with the ability to mount the battery anywhere in any positiion.
upside down if you want to !
Something that cannot be done with standard lead acid batteries.

How well does it work wuith the GS charging system? I believe that lithium batteries need a special charging system?
