YTZ7S/ Any problems with this bat?

[throttlecable]

Just trying to get some feedback on the performance of this battery compared to stock. Has anyone experienced any reliability issues with it? Does the YTZ7S provide enough juice for repeated cold starts? The stock Nytro bat looks like overkill, and appears to be a suitable application for maybe a Kenworth. I would really like to make the switch, but would appreciate some intelligent honest info from people who know. -Thanks

Had it now its an ornament on the shelf, and once in a while I pack it in my backpack if im the only sled with a battery. If your running the heated grips, headlight and starting a few extra times and its -10 and lower it seems to wear down too fast.

Had a couple of rides with mine, worked 100% so far. My thoughts where the only time it would be cold enough to have trouble starting may be at the beginning of the day. I carry jumper cables in my truck and sled so I could always jump if I needed. Through the day when the sled has been running it sparks right up with no trouble as of yet.

I had a post on mounting it is well.

Over Christmas we were travelling to a sledding area and the temperature dropped to -23C through some of the mountain passes. It stayed cold until just before we unload and it was about -12C there. I have a ytz7S and my buddy has a 10s, and neither of our Nytro's would start. Both batteries are kept on tenders when not in use. We boosted the sleds and didn't have any other problems the rest of the weekend.

I never had a problem before this and haven't had one since. If the sleds would have been in an enclosed trailer I don't think it would have been an issue.

So if I were to remove the headlight, the reduced draw might make the YTZ7S liveable in most conditions, except for below zero cold starts...maybe,...still undecided.

Honestly, I wouldn't worry about the light at all. The sled charges the battery fine. Like I wrote above, I have only had trouble the one time and it was pretty cold. At -15C (5 F) I have never had an issue.

Worth a try I guess. I will keep the stocker in the trailer just in case. Thanks again for the reply.

From what I have herd and read I am going 10s the couple pounds is not worth it to me.

 

[throttlecable]

How much different is the 10s vs. the 7s vs. stock as far as weight, and cc amps etc. etc. ?

 

[Mountaintech]

The next time I will be buying a 10s.

 

[OFT Racing]

I think they say the 10s is 9 pounds lighter than stock and the 7 is 12 pounds, Can someone confirm this? All the reports I read on the 7 is people are running battery tenders and keep jumper cables near and the 10s will work more or less as stock. To me its a no brainer, I wanna ride not even have to think about something just to save 3 lbs.

friend of mine had 10s and it didn't last and he always kept it on a tender. I've been running a 14 for a couple years with no problems. starts at -20 and i don't need to keep it on a tender. only 4.5lb weght saving though

i'm on the fence still with this decision,,,if the thing doesnt start in the cold temps,,its an exspensive chopper ride out,,,other than using the elect starter,,what emerg start could a person use,,i can't realy see a strap on the clutch workn,,,any other suggestions

 

[summitboy]

You would be surprised about the strap in the clutch it works way better than you would think. If you run in the hills exclusively a 7s will be no problem at all. I have been running one for 3 years and no issues on a T Apex. I have my sled in a heated enclosed so my sled never is cold soaked. If you ride in Ft Mac and your sled is parked outside all night not even the stock battery will last LOL

 

[Mountaintech]

Strap around the clutch works well.......even on a gear reduction RX1 engine. Try it some time just for the hell of it.

 

[..SNAKEBIT..]

on my scale (not some highly calibrated scale)
stock battery = 15.0#
YTZ7S = 5.5#
weight savings = 9.5#
