I have run a few different Lithium batteries. They indeed are lighter by a huge margin.
If it is a very cold start in the morning the Lithium doesn't have the same Cold cranking power.
Beyond that I love the Lithium battery option. If I had a Doo without a pull cord I probably wouldn't use a Lithium.
Given Poo has a pull cord on every sled I have no problem making two easy pulls on the occasional very cold morning with my Lithium battery.

Thats what I do. I usually have to pull start it in the morning but then its good for the rest of the day.

 

Exactly...lithium batteries lose a SIGNIFICANT amount of their cranking power below 32 degrees....I don't even want to think what they would be below 20 or 10!!!

 

Could be exactly what I'm looking for. Let me know if you find a site online with a good price and the cross reference part number.
If I would have ordered a snow check, I would have skipped the ES, but all the factory choice sleds in the area had it. After my 800 without ES, I was thinking the 650 would be easy.

FirePower HJTX20HQ-FP Featherweight Lithium Battery at Amazon might be worth a try for me.

 

Go with EarthX ETZ14C. I've had zero issues. The WPS one was not good in the cold.

ETZ14C

The ETZ14C LiFePo4 snowmobile battery is specifically designed for electric start snowmobiles. It delivers 330 Cold Cranking Amps and only weighs 2.5lbs.

I've heard you should bump the starter, wait a minute, then go for it. This gives the lithium battery time to warm up.

 

A 20 has more cca than a 14 does was my point.

 

ETZ14C is specifically designed for snowmobiles and cold starts.

 

Thanks. I took your advice and will try this one this time. My others were lacking CCA when below 10 degrees on a frozen cold motor in the morning. Never really an issue that bothered me much because on the butt cold mornings I'd pull start it once. Never a problem for the rest of the day. If the ETZ14C Earth X proves to kick ass on the Cold mornings I'll then realluy have something to brag about. It really blows peoples minds when you hand them a stock lead battery to put in one hand and a Lithium for the other. It's a bit hard to believe the difference until your holding both in your hands.

 

Two full seasons on wife's 900 Ace with EarthX ETX36D, no problems down to about 0F. Have not tried starting any colder.

 

Has anyone tried the Banshee Lithium Battery ? Found on Ebay.

 

howd you guys like the ETZ14C after a year of use ?

 

Mine was great last year. Never really saw a Cold Winter to test the toughness but there was never any complaints to speak of either. Hoping this year turns to be a better Winter than last year was? Ordered another for the new 2022 sled that hasn't landed yet this year. Thanks for the advice to try this one.

 

Mine worked great even at -25 C. Started the sled last week for first time this season and wasn’t run down at all.

 

what is the weight savings?

 

11 pounds

 

It's the weight savings in the wallet that's an issue for me!

 

Yes. Its easier and cheaper for me to lose 10 pounds than it is to buy a battery that saves 3 pounds. Dont get me wrong, I love the idea of new tech, but from a practical standpoint, I may only consider a lithium battery once my stock one gives up.

 

My 2015 is ready for a new battery....so thinking I'll move the 2022 sled battery to the 2015 and fit up the lithium on the new sled.

 

I just ordered a Noco Lithium NLP20 for my 2013 XRS for $179 off Amazon. It has a 5 year warranty and claims to work for snowmobiles on their website. They have good battery chargers so I’ll see how well the battery works.

 

No question the lithium stuff is more expensive and its pretty hard to justify buying one just for the weight savings alone - though it is much more than 3 lbs lighter. A lithium won't weigh half of what a conventional lead-acid one will. The next advantage is lifespan - the first lithium I bought was for my FST (that OEM battery weight a LOT) and I still have that same lithium battery in the sled 10 years later. Still works as well as when it was new. I put one in my '12 Rush, ran it for the life of that sled, ran it in my '15 Axys for the life of that sled, will be able to put it in the next sled when that comes along. Good lead-acid batteries aren't cheap anymore and if you have to replace a couple of them, you'll have spent just as much as if you just bought a lithium and you'll be able to drop that lithium into your next sled.

 

The Noco battery I ordered weighs 3.73lbs and I just weighed my old dead battery at 13lbs so its over 9lbs lighter and has a 5 year warranty so I’ll swap with one in my next sled too.

 

I ordered the Noco battery from Amazon today and it was delivered 2.5 hours later. Crazy.

 

Well, that is a pretty good weight savings. I will still wait til my current battery poops the bed before I swap it out.

 

Swapped my OEM for an X2Power lithium. Didn't even register on my scale... They say 2.86lbs.
I always pull my sleds on the first start of the day, so not worried about lower CCA. Has been as advertised so far.

 

Put the batteries on top of each other to figure out the weight.

 

Look at the big brain on you!

 

10 lbs is pretty significant and worth a couple HP

 

Agreed. Good weight savings. Combine that with the 10 pounds I could stand to lose, and you have a rocketship.

 

So you're back to stock weight on a non e start sled.

 

Anyone use the firepower lithium battery that Bikemen performance is selling?I picked one up but have not tried it yet…

 

I have. I found the EarthX to have much better Cold Cranking amps.
