weight-less lithiums

anti-gravity, super light weight is not the way to go- search here on X
WPS featherweight- seems like a good alternative-( 490-2520 ), time will tell

just get an oddessy 625 and be done with it. they last forever. i just pulled one out of a ski i blew up 2 years ago, charged it and it works great. i've got another one in my octane. it was well used when i got it and 5 years later its still good.

I would like to lighten up the ski as much as possible.

I like the anti gravity lithium batterys

But do they require any maintance or charging

Im lookin to put a battery in my ski and have no issues. I ride 3-5 times a week and live on the lake so i just wanna hop on and go

Do a search on here for antigravity, or rather antiquality and you might go a different route. I've had good luck with Earth-X batteries and I've heard the WPS batteries are also good if lightweight batteries are the way you want to go. If it were me putting a battery in a 2012 sj I wouldn't spend the money on a lithium, your money would be better spent on other upgrades. Saving a few lbs in a 350lb hull won't be very noticeable.

I bet if you put it up as a poll, the ETX-9 would be the clear winner FOR THE AVERAGE RIDER. The ETX-9's are the lightest AGM battery available, have good solid lead posts, are compact enough to fit in tight alternative spots and can be purchased in the $50-$75 range. If the rest of your electronics are in good shape, the ETX-9 will run dual bilge pumps and crank 900cc's all day. If it won't, the battery is not your problem.

I like cheap, simple and bulletproof. Lightweight batteries are none of those.

The ETX-9 is a good wife, the lithium... an expensive mistress at best. :p

I don't suggest ETX-9s for standard applications. The 12 or 14 offers much more power and reserve with a considerable weight savings over stock. The 9 is small and lighter than the 12 or 14 by 1-2 pounds, but only offers 120 amps versus 330 stock. It will work, but in my experience, the 12 offers almost another 100 amps at a pound or so penalty. Here is the link to the data sheet:

Lithiums have their place but not in your ski lol. They work well for big displacement, 240 lb compression custom skis on total loss. They are way too high maintenance for standard use, and will not likely live on a charging system. That being said, I love my antigravities! A fair amount of the issues you read about are user induced. I've been on the same one since Memorial Day (200 gallons plus of fuel @ 230 psi), with no issues. I did a capacity test and its still around 75%, which is great considering the abuse I've put it through. Once again though, it's not for your application.

Odyssey PC 310 is my favorite. 5.9 lbs. Charges off the generator coil. No need for expensive chargers. Super durable. Holds charge forever. 310 cranking amps. Install and forget for 5 to 7 years. Lithuim Poly batteries become unstable and a fire hazard eventually.

The 120 amps the ETX-9 puts out is ''cold cranking amps'' is measured at 0 degrees Fahrenheit because at that temp all batteries are operating at 50% capacity , and thats the minimum it must put out at that temp , at 70 degrees that battery will still put out at least 200 amps im positive and my eng draws between 60-90 amps to start ..... correct me if im wrong ........ but being lighter in weight than the 12 or 14 it just cant sustain the heavy load for as long of a period, for instance trying to start a previously submerged engine .. the ETX-9 starts my 195 psi engine with no issues and does it every day ,,,, the 12 will crank longer and the 14 even longer and offer more amps at the lower temperature for a longer time period IE :''capacity'' ., just saying that it has WAY more than 120 amps at 70 deg F :)

Regardless of how they are rated, its still only about 1/3 of the stock battery, and as you mentioned, does not provide the reserve power. :)

If an ETX9 doesn't crank your ski all day, then you have issues with your ski that can't be blamed on the battery. If your chit runs like it should, the only time you'll need more than an ETX9 is if you sink it. In that case I recommend you carry a spare full sized battery in your truck where the weight won't hurt anything.

You guys crack me up. I never said a 9 won't crank your ski. Read the post. Ill refrain from giving my advice as its clear I don't know what i'm talking about, and my skis are beat up and run like chit. :)

Every time someone tries to answer a question on here it turns into a pissing match. I stated my beliefs and opinions based on my 20 plus years of building skis and my own experiences, not to mention I teach this stuff for a living. Now you guys are picking at me over things I didn't even type. I'm not here to argue with anyone. The OP can install a 9V battery in his ski if he wants........to each his own. Responses like this are why so many knowledgeable people from our industry refuse to participate on the boards. Someone always finds a way to nit pick their post and cause drama.
