EarthX ETX36D Lithium Battery

judger101 · Oct 31, 2014

I am doing a few upgrades to the Nytro before snow flies and a lightweight lithium battery was on the list. I did a bunch of research and it seems like earthx is the best (most expensive as well!) Looks like this is about an 11 pounds weight savings for $350.

I live in ND so cold was a serious concern. In reviews I saw they are using these in AK with success so I thought why not give it a try. I also always carry my antigravity lithium microstart just in case (you need to buy one of these!).

I will be posting some picks. I got the earthX today and it is about the same size as the stock battery just a little bit shorter. I know what 10 lbs feels like, but when you put them each in one hand it is amazing the difference. If you think about an extra 10 lbs hanging high up on the side of a sled it is quite a bit.

I will be posting pics and performance updates throughout the year.

Had one in my wife's apex for a few years and it's always started the sled. Even at -30F it has always started. Thinking of getting another one for my sled.

Think i read somewhere you cant use those micro boosters on lithium batteries

judger101 · Oct 31, 2014

that would be unfortunate, i have an email in to earthx to figure that out for sure.

here is a size comparison, like i said it is just a little bit shorter than stock

on my cheap scale i show a 10.41 lb weight loss.

at a purchase price of $350 this mod cost $33.62/lb weight loss.

I have one on the way. I want the extra crank power. Don't really care about the weight loss. It's a bonus

the earthx folks say you can use the smaller lithium jump starters on these batteries

Bought one of these for my Boosted Viper. Sled fires right instanly run for a few seconds then quits, if I keep firing it up it throws a couple codes ( never looked to see what the codes were) put the factory battery back in fires up and runs perfect. Battery was/is fully charged.

Wonder if there was something wrong with yours? Did u ask them about it?

I have been using earthX for 2 years. No problems. At -5F it took 4 starting cycles over a 10 minute period to start the nytro

i decided to put on a hand warmer kit onto the battery. in cold weather it will warm up the battery heat wise as well as by drawing a current. this is a $7 hand warmer kit off of ebay with some foil tape.

We tried 3 of these batteries last year on the Vipers and they wouldn't run. Sent them back for a full refund.

Thanks, I should have asked you.
Nice light paperweight now.....

On a side note, the Antigravity batteries work perfect. No issues. We use the 12 cell models.

I had no issues with my lithium battery for the last two seasons once I learned the proper starting technique for COLD mornings

calltrex · Nov 6, 2014

Im cancelling mine. Ill wait till a better design or something that's proven. Ill just bring a jump pack incase i ever need it. Also doubles to charge my gopro stuff if i need to

I would LOVE to know if this works and doesn't hammer the battery power storage levels.

i will do quite a bit of testing. winter i coming in ND, next week is going to be in the 20s, so the below 0 days cant be far off!

Will be interested to read your comments.
the ONLY times I have had any issues with Lithium is after a VERY cold night.
When they get into the negative temps, it just takes "longer" for the battery to self-warm. It always comes around, but sometimes it takes longer than I would like. So I would be very interested to see if there is a reasonable short cut to warming the battery in the morning.

Is that the YTX 12/12 you were using?
