Best Li-Fe battery I have seen so far

[D-Roc]

nice moves man!!! that means mine should be coming into london ontario dealer soon too!!! finally my quad can get my old deka and i get a new 2.idon't care lbs battery haha. That is pretty good price i think with a 2 year warranty. scotts has lasted 7 weeks so far, haha. who is going to saltwater test these things?

I just pulled the trigger on the same battery as Waternut, plus charger. (Except I chose the opposite polarity location)
That 15% discount was pretty sweet.
Going from a 14lbs battery to 1.7lbs :woot:
That brings my RTR weight from 259lbs to just under 247lbs, with 2-2.5 gallons of gas.

From Shorai:

"CCA Ratings for lead-acid don't translate well in comparison to SHorai LFX, because we typically hold up to 2V higher during cranking than an equivalent-rated lead-acid battery. Since it is WATTS that starts your vehicle (A*V), this means that we crank much better than our CCA specs indicate.
"Amps" never started a single motorcycle. Watts (V*A=W) start motorcycles. And batteries don't supply "CCA" in the real world; they supply the current drawn by a starter motor, which is based on the load on the motor, and the voltage delivered from battery to starter.

As for voltage, 12V is a "nominal" rating. A fully charged AGM will provide about 12.8V, a fully charged Shorai LFX about 14V.

Since lithium batteries start with a higher nominal voltage, and our LFX hold voltage under load better than the lead-acid we replace, we deliver more watts per CCA rating. As stated in our FAQ, if you are interested in actual cranking performance rather than a CCA rating designed for 12.8V lead-acid batteries, you can multiply our CCA by a factor of 1.5 for a closer comparison to lead-acid CCA ratings, in terms of delivered cranking speed.

To re-cap, CCA ratings were never intended to convey anything but the relative voltage performance of lead-acid batteries, under a given "real world" load. Since the voltage delivery of lead vs lithium can be very different, CCA ratings alone do not provide a full indicator of relative performance."

this is good news for me and my older Flame TL, because it quits sparking when cranking voltage drops below 10V

In response to the question I asked Shorai tech support about when to cut power on these batteries to prevent damage... They responded with "You want your battery to last a long time, and perform well. As such, it is best practice to insure that AT LEAST 30% capacity remains in the battery at all times. It depends on the load, but assuming about 2A draw, I would be sure to cut off at 13.0V (or 12.9V at absolute minimum)."

My 800 gph bilge pump sucks 3amp. Not sure on total loss draw but looks like I better cut off at a little above 13v. That seems bad but I guess these normally peak at over 14v and quit at 13v while a normal battery peaks around 12.8v and is dead around 12v-, that's not too bad.

The current draw has nothing to do with the capacity voltage (only that you reach the 30% capacity threshold faster with a higher draw). If they say 30% capacity is 13V, then it does not matter how you get there.

These are nice batteries, someday when I reach "baller" status (with a new hull and rider ability) I would splurge.

There is some good battery info in this thread. If you take one thing away from it, proper battery maintenance goes a long way.

nice moves matt, i think you will like your battery. wait till you hold your old battery and then the new one....haha.

 

[McDog]

Somehow I missed this until now. I can't wait to see how this does over the summer. It would only be a 4 pound loss for me but my little Dekas struggle a bit and I bet these don't.

 

[D-Roc]

i run the 9lb+/- deka and have had no dead batteries in one day ride. 4th season, they are good batteries and i hope these shoria batteries do as good.

Ok, so if I read write, the shorai battery would be a great choice if you are going to buy and use their charger? But If you dont think you would then itd be a better bet to go with the ballistic battery? Has anyone here used the ballistic yet?

I wont be running total loss or anthing, just using it on a mostly stock 61x as an easy way to loose some quick lbs

Well the 30% is considered a resting voltage which means when under a load, the battery voltage reads lower than what it really is. This was my point for emailing Shorai. If you measure the voltage of your current battery with nothing, it may read 12.8v but if you read your voltage while cranking the engine, it will probably read below 12v.

I think both brands have pros and cons. My recommendation is to read up on both of their sites and see what will work best for you. They're basically priced the same so the application will depend on the selection IMO.

if your using a charging system than it would be a different charging that the battery will recieve than with TL and using the smart charger. scotty2t is using the shoria on TL with the green 2amp battery tender charger. he just gives it a quick 15min charge before he rides. doesn't keep it on float mode.

When your riding a carbon, 1000cc flatwater ski to drop 8-10 lbs is a big deal!

But more important is these batteries keep high voltage during starts which also will help with ATP flame/epic's

We have been using these a123's for years in the RC heli's and big gas planes

the guys putting these batts in their ski are on a waaaay different level than most....


its almos a competition just to bring the lighest strongest ski to the beach



by the time you spend 30k to have truly lighweight ski, 80 bucks to save 6-8 lbs is the cheapest part on the ski! .....I say 80 as a decent batt costs 80 regardless........




if you are a bargain jetskiier, this mod simply isnt for you....

tushay, im beginning to rethink my first post

 

[D-Roc]

come and get on the wagon man, we got room.

Think about it this way: For x amount you get a hull that weighs 56lbs (taking my own as example). X is rather large.
Now for x + $130, you get a hull that weighs 46lbs.

It's a no-brainer, I think.

Well said Matt, I wasn't trying to be an a** hole with that post, but in our FW setups weight is everything , also where the weight is placed. So to drop that much weight is a big deal, now if only I could drop 10 lbs!

Ok I just checked when I got home and a lot of the batteries are now in stock on the Shorai website. I got the LFX14A2-BS12 ($155) with the charger ($80) that will balance your cells and diagnose their health. If you go to http://www.track-junkie.com/Shorai-Power-Battery_c679.htm and enter in the code HPC2010, you'll get 15% off. With the coupon code, my total came out to about $198. SWEET!!

I jumped on board as well, but kicked it up w/ the LFX18...w/ 270cca

15% code worked, thanks!

Wow, I just got back from vacation and haven't seen this thread in a while. I'm glad that some guys are trying these Shorai batteries out with me! So far so good, but no long term reviews as of yet...for the price, and what I've gained from 2 months of freestyle light-weightness in my eyes it has already paid for itself!

 

[D-Roc]

sooooo, did you get me my battery scott? lol. welcome back scott.

 

[Matt_E]

They told me Friday that the stuff was in stock and ready to ship. But I have not gotten a shipping notification yet.

 

[Waternut]

I got an envelope on Monday with track junkie stickers, a koozie, and a brochure for the batteries. I guess they drop ship the batteries.
