Best Li-Fe battery I have seen so far

[sicksxr07]

I had a day good first day with the 14ah shoria I took volt readings 14.19 one hr after full charge . Started and stopped ski 5 times before first ride. 25min later multiple stop/starts only dropped too 13.9. After half hr went out again for another 25min session again multiple starts only dropped to 13.34 tested ten min later went up to 13.40. Cool huh!!!!
Rode one. Last time only dropped to 13.19 and still cranking like craZy running 180psi. Kawi 850 with advent tl. No bilges just scupper.

Gets a A+. Rating from me so far

did you happen to read the volts when cranking the motor, that is the main problem for the flame users. it must stay above 10V.

I put my shorai back in for this weekends riding, worked great for the 3 hrs of riding I did each day, Saturday and Sunday. I can notice a big difference in weight with it installed. 8/10 for Shorai.

I give it an 8/10 because it is easy to run dead with msd total loss without care. noticable weight loss wins the 8.

Who did you order from?
Mine shipped the day I ordered it

410cca and 2.5lbs nice battery man!

Hopefully it works, I'll be testing it this weekend

Someone should try the 4cell it weighs half a pound haha

I think thats where Aircraftsal ordered his, he's still waiting on it too

scotts is 1.55lbs and must be a 6 cell. 6cell=3 cart tanks of gas scott or more? 4 cell probably last for 1 cart tank and a trailer start.

 

[scotts2t]

4 tanks easily with 2 trailer starts, after that would need a charge...I always bring my spare batt anyways, other people use it more than I do. For the time that I use the shorai I can definitly go bigger, 10lbs less bigger. it's sweet.

Shorai doesn't use the same cells that all the other batteries use. The ballistics and such use A123 cells which were designed for power tools originally. Shorai uses custom cells that they developed specifically for automotive applications. Just because the shorai is 1.55lb, does not mean it's the same as a 6 cell ballistic or even a 12 cell. The batteries are totally different.

cool, that is good to know for when choosing which one to buy. me and scott where just trying to figure out how many cart tanks he gets per charge on his ski. he has a single 48. I ended up getting mine in today. it is nice and has lots of stickers. it is about 7 pounds lighter then the deka it replaced. I gave it a quick 2amp charge and checked the volts at 14.38, nice. I installed it in my homemade battery tray and the width is the same as the deka. is was about 7/8" smaller in depth and an 1 2/8" in height. i didn't start the ski but i did crank it over. I thought i forgot to put my spark plugs in.

You must have the larger case style.

 

[D-Roc]

yes sir i do. i used a bit of the padding to wedge it in but my strap bolts down onto it and keeps it in place very well. haha at least sitting in my garage. i will water test it and bring my meter to check after the ride what it cranks over at in the water. i put the sticker on the beer fridge.

Where are you getting your information from? No where does it say that it uses A123 cells.

Here's a quote from Ballistics site
"The EVO 2 uses custom made proprietary cells, cases, and connectors that are made specifically for the purpose of starting motorcycles."

I made a custom glass box for my shorai. covered it in turf, then covered the battery in the supplied sticker foam and the thing was nice and comfy

I'd like to see some comparisons (from members) on ballistic and shorai just for grins. They both seem to be using custom cells (which I'm sure are different) that will perform differently. It'd be interesting to see how they compare. Will one crank better, but not last as long etc... Weight vs performance bla bla bla. Keep on postin guys. Lovin the read. Thanks to all sackin up!

 

[D-Roc]

it wasn't hard for me, my grizzly 4 wheeler needed a new battery so the deka is going in the quad and my ski looses 7 lbs. yeah!

Maybe they aren't A123 but I find it a tad suspicious that the Ballistic batteries quote 13.6v (charged), 257 cca, and then list an equivalent A/H rating. Meanwhile the other battery manufacturers that advertise as being A123 cells quote 13.2v (nominal), 240cca, and list true A/H ratings. If they aren't A123 cells, it doesn't seem like a very good business practice to develop a brand new cell that has a 6% increase in power delivery. Even then the 6% increase from 240cca to 257cca could just be the best rating rather than the average or measured at a non-standard temperature.

For reference here is a good post that I found interesting on a Ducati forum. http://www.ducati.ms/forums/1008107-post16.html Someone questioned the Ballistics claim of proprietary cells vs A123 cells and the Ballistic rep stated "The cells we are using are built to our specifications, they are not commercially available, off the self components like the ones use by some of the other LiFePO4 batteries on the market. The biggest advantage to the Cells we are using is in thier internal resistance, but this is not a spec that anybody would notice or be able to quantify...so I don't list it."

If we can't notice or quantify the change, what's the point of changing? Sounds like smoke and mirrors to me. Just saying... A123 cells are still very good though so don't take my post as bashing the product. The Shorai batteries could be A123 cells or a slight variation as well. I bought the Shorai because I liked the charging method.

Having a better internal resistance can definitely help. They (Ballistic) do rc car batteries (among other apps) , and sell some matched packs, which racers (rc car racers) are super anal about having very closely matched packs. That being said, they should have a good handle on the experience to make a quality pack. Or... They could be full of poo too lol. It happens everywhere.

How my battery sponsor produced cells.

1. Buy a crapload of cells from Sanyo, Panasonic, or whoever.

2. Charge and discharge them all a number of times at controlled rates and temps.

3. Test all the individual cells for run time, peak voltage, disch rate, charge rate, internal resistence and other crap I can't remember. At this time each individual cell gets a sticker put on it which lists all these numbers for that individual cell.

4. Then the batteries are sold in matched packs, meaning the numbers on the stickers are extremely close. They came in 4 cell, 6 cell and some 7 cell packs.

The low number packs were sold real cheap for recreation, or sport packs.

A company like Ballistic that does battery matching like this, I would tend to trust a bit more mainly due to their experience. Other companies were around that would buy batteries in bulk, but not match them. Or in some cases not cycle them properly before selling.

Improper charging and discharging will break down the internal resistance and kick the batteries butt a bit too.

Just my .02 on previous experience, but it's been like 10 yrs since I raced and I'm sure cell tech has changed.

Got my battery yestoday. Ordered 5/13. It's light !!!
