Anyone who ran the stock lithium in there 18 f or fix have any input

Is 19 any different than 19?

Thanks in advance

I have an 18 F and after one trip it went in a box and bought an antigravity battery big as i could fit. First trip had booster pack and setup booster plug wired on bike but was a pain in ass. Was minor trimming to fit antigravity.
No issues having to boost since.. i believe 19 has some type of of upgraded starter but i still wouldnt trust that little battery.

I had nothing but bad luck with my antigravity battery. from not starting in -25 to dying on the trail when I ran headlight AND handwarmers (prob need a bigger stator). I went with a yuasa lead battery and seems to work a lot better. weighs 1lb more but when theres 60lbs of snow and ice packed in every nook and cranny on the bike, youll never notice.

still uncertain, any other feedback?

For cold ops use lead acid , they simply work much better in the cold.

Ask Rick they ave had lots of issues with the lithium ion in the cold.

If you get a 19 I may have to upgrade as well just to keep up:face-icon-small-win

An Antigravity rep had chimed in on the Beta-users Forum on Thumpertalk and had even come out and said that he/the company does not recommend LiIon for temps under 40-F, which is already considered cold-ha!

He recommended cold weather riders/snowbikers stick to either AGM or Lead Acid.

We tried a LiIon last season and it blew-chow all winter long.

I just got a new AGM for this upcoming winter as I had good luck with the AGM last winter. I still had to use the boost pack for the coldest of days but otherwise, in temps above 10-F it worked well.

I ran the stock battery all year with no issues. I would plug it in to the tender the night before a ride and it worked great even on the cold mornings. I have 80 hours on the bike now, still on the original battery.

My friends who do not use the tender got about 40 hours out of their batteries before they stopped working.

Worth the upgrade

I had a failure on mine second ride last year. I was told by the dealer boosting or bump starting the bike when or if the battery is in safe/low power protection mode would result in damage to the battery. I ended up getting a standard battery for the winter months.

You got a model number for that yuasa?

Heck I might buy that battery just for the ease of attachment

I like the look of that Antigravity battery.....sometimes when you are connecting 2-3-4 wires to positive and negative terminals with traditional style battery connectors, it is a challenge..... this looks way more gooder in that regard.

I ran an 18F with the stock lithium for the last 1/3 of the season last year and had no issues whatsoever with the stock battery.
I also have had two 450fx (16 and 17) both of which I switched the stock Yuasa 7 (lead acid) to a WPS lithium battery and never had an issue with those either.

YTZ7S

Did you have to modify the battery holder to get the ytz7s to fit?

Another option for ultimate starting ability is to just mount a large lead acid battery on the snowbike kit.
Extend the terminals.

That way you can buy a cheap battery but have better starting than the $200.00 battery.

yes, it already had a larger than stock anti gravity battery in there (same size as the ytz7s) and it looked like it has been cut to accommodate the anti gravity one.

One of these drop straight in with no modifications

, seems to be working well so far

I can say is I had nothing but problems with my lithium battery and once I went to lead acid had to jump the battery once or twice when it was super cold

Anybody have the dimensions of the factory battery?
