Shorai battery for KTM990/LC8

I didn't find many pictures of the new Shorai battery alternative for the LC8 in OC so I thought I'd post my install.

Shorai is a new company in the US. I met the President of Shorai USA, David Radford, at the Seattle Motorcycle Show this year. The batteries looked amazing, and so light I thought they were just demo cases with nothing in them, but David said no, they were the real thing.

Read up here:
http://www.shoraipower.com/

I got one for my 2007 KTM 990S. The original lead acid battery was finally dying and I needed a new one. I wanted to try something new and these appeared just in time. I decided to give this new Lithium Iron Phosphate battery technolgy a try.

I chose the LFX18A1-BS12. It came in a box with a selection of sticky-one-side foam strips to help it fit the usually larger space the OEM battery took. You have to trim to whatever fit you want






Here is a physical comparison of the
OEM 8.6lb Lead/Acid v.s. 2.12lb Shorai (6.48lb difference)
weighed on my digital postage scale at home, not a lab test scale.

Front



Side


Top





I trimmed a few foam pieces and installed in the sides of the rubber OEM battery base






Then installed the battery in the rubber base






and installed in the bike. Note the foam strip I used in the top lid of the battery box to help hold the little Shorai battery in place.



That's it. Quick and easy install.


I topped off the battery with a Shorai approved Battery Tender



or




Then came the test. WOW! It cranks the bike with serious authority easily as good or better than the OEM Yuasa lead/acid, even at 30F in my garage. Bike fired right up first crank. At real cold temps, the first cranking cycle may seem slow, but it heats the battery internally (a good thing) and 2nd crank cycle and after will be full force. I was impressed. Tried half a dozen starts after the first one and it spun the bike over quick every time!

Happy customer so far.

Now for the long term testing with my all year, all season commuting and trips, heated gear, etc...





BTW, I got mine at the first local biz to get them in the Seattle area, I was anxious They also offer an ADVrider discount.

Thanks for the pics and write up. I am in the market for a new battery too. How much are they?

Fair price as far as I can tell. I will give Alternate Cycle in Kamloops a shout. He seems to be the only dealer in Canuckistan so far. Cheers

very cool cyborg. i just bought the same battery from cj. looks like the install was a piece of cake. did you have to do anything funky with the connections? or did they land right on the posts?

The Shorai sits about a 1/2 inch further inwards than OEM in my install but the cables had no problems connecting.

Worth the weight? Hopefully...

Thank you for taking the time to provide the comparison and details of the simple install. Like others, I too will be interested in seeing how this battery holds up over time. The weight savings seems substantial, even though to begin with that mass is already about as low as it can get on the bike. Should help with pulling off those nac-nacs a little quicker now!

Cyborg,
+1 on the excellent write up and pics. Good Job

I have the TurnTech 5.0 Amp Hour battery which is I believe a similar type battery in my 450 2008 xcrw. The battery is about a year old and has never fail except once. I was riding with lights on, fan going and stopped by a sheriff. I left the lights on for a few minutes, trying to be a nice safe guy. It would not electric start but kicked right over with the Ol' foot. Since then I think 5ah is a little low.

Question: your bat Cyborg is a LFx18A1-BS12. Is it is a 18Amp Hour? I should call the company but Just wondering out loud?If so that would be great for my 990.

Yes, That's what the "18" stands for in there Part number system.

Great write up Cliff.

We're stocking these and getting all our 950/990's setup w/ these for this season's trips. Can't wait to get back to Moab in March.

Are you sure ? I thought they were BS12 - 12Ah batteries. 18Ah is way over kill, no ?

edit : just checked their website and found that you were indeed correct. BS12 = 12V. Sorry for that.

The more Ah the merrier when you run extra loads like heated gear & grips or you forget the GPS on when the bike is off . I'm sure a lesser Ah version would work just as well in terms of starting the bike. The Ah doesn't relate as much to starting, just longer term drawdown if your alternator is not quite keeping up. The cranking amps is what is of more concern for spinning the starter quick. You can go way overkill on cold cranking amps if the bike say only uses 200CCA peak and you get a 480CCA battery. The system can't use/doesn't need that much current. I don't know what my 990S uses peak, but the OEM Yuasa is 190CCA IIRC and the Shorai spins the bike harder and faster than the lead/acid Yuasa so I don't think I need much more.

Just ordered one from ADVMachines. My OEM from June of 2003 is still doing the job, butt 8 years is too much to ask from any battery. Think I'll retire it to my museum of Over Extended Parts (along with my OEM LC8 water pump, fuel pump, and front rim, to name a few). This Shorai is so light you could carry a spare in the luggage for those long trips, if so inclined. Thanks for the writeup cyborg. Great addition to the HOW.

More Power!

Great Post,

If any of you who are running the Shorai batteries actually deplete the charge in one and have to charge it, please let us know how it responds to your charger. Same for just a preventative trickle charge. AGMs, Gels and LI batteries all respond differently to a charging cycle and have differing "Ideal" charging rates. The problem is that our motorcycle's internal charging circuit as well as the conventional trickle chargers most of us have are optimized for lead acid charging rates. This is why some earlier versions of so called "Super Batteries" end up with much shorter than expected life spans. I'm not saying that is the case here, I'm actually interested enough to want to know the outcome. I'm just saying it may be the only potential down side.

Just installed one on my 950 adv s and it is nice and strong. Super easy install and so nice of them to include the sticky foam to make it that way.
