  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Ballistic 4 cell installed 2011 TE310, CV4 battery is the same.
No issues, a bunch of rides more than a few races.
Light simple and inexpensive.

So do you or have you charged yours? if So- with what? Seems shorai unit is going one step further above traditional charging- but aside from that What's the REAL world actually doing or finding they need to do with these Lifpo4 batteries?...

since they have nearly zero discharge rate, I had thought storing in my house for the winter and not charging would be "fine"? think I will need a special charger? obviously it is normal for me to have one in the garage... so it seems weird not to for this battery...

I'm still running a Turn Tech 5 AH that was previously cranking my 510. Good little battery. I've cranked my cold soaked 250 at 26 degrees! It took several attempts but the battery finally warmed up enough to fire up the bike. I've found that seveta/ short bursts with the button warm the battery adequately to obtain rated cranking power. I'll never put a lead acid back in this bike. Matter of fact, when my street bike battery finally quits the replacement will be a Lithium as well.

I have a TT 5AH too. Over a year old and working fine.

I beat it up a bit fixing the starter too.

No they don't. From their website:

Q. Can I use Lead-Acid battery chargers or charger/tenders?​

A.​
Yes. HOWEVER, you may NOT use a charger/tender if it has an automatic "desulfation mode", which cannot be turned off. We have confirmed with Deltran, makers of the "Battery Tender" brand, that their products do NOT have a desulfation mode, and are therefore OK for use with Shorai LFX, for example. But the best possible charger/tender for Shorai LFX is the SHO-BMS01, which will be released on about March 15th 2011, we expect. It uses the 5-pin BMS port in the LFX batteries, in order to monitor, diagnose, and balance the individual cells during charge. And it also has an optimized storage mode that will give the longest possible service life to your LFX. ​

Thanks for clearing that up, the paperwork that came with my battery stated they recommend only using their charger stating something along the lines of other chargers may damage the battery.
 
I can tell you from use of Lipo type batteries with my model planes and helicopters, the reason for using the special charger. Lipo type cells are usually run 3.7 volts while LiFePo4 are 3.3 volts nominally. It is suggested for best performance and safety that they be charged with a special charger that is able to monitor each cell's voltage, temperature, amount of Mah taken in, etc. If anything goes out of spec, the charge is stopped immediately. A Battery Tender is smart...but not that smart.

While LiPo cells are capable of higher discharge rates they are also to be used with care. These are the cells found in lots of cell phones in addition to radio controlled aircraft and surface vehicles. They are wrapped in a heavy duty plastic/foil and are flat and rectangular in shape. However, if they are treated or charged improperly, they will quickly lose performance OR they can and will puff up, rupture and emit what looks like flames from a road flare. Modelers have lost their whole aircraft and even a few homes due to a lipo fire. I've seen the melted charred carcasses myself.

The LiFePo4 cells are more closely related to a NiCd or NiMh type rechargable battery in that they are in a traditional cylindrical case. Thankfully, they are also more durable and forgiving, but not by a huge margin. They are also capable of many thousands of charge cycles with excellent retention of stored voltage over time. I would suggest that you use a battery tender only as a stop gap until you can get the proper charger.

I can tell you that for modelers who have changed from NiCd, NiMH and even LiPo cells, they are much happier and feel much safer using this type of cell chemistry.
 
I'll get my Shorai LFX14L2-BS12 by tonight and put in my 09TE450.
Seems these are pretty well established but I'll give my opinion of it.

In terms of Battery options- there are now a ton of these Lifpo4 type batteries being made by many companies- many are listed here. The Shorai is just one of the many good options in this category it appears. I went with it because it has positive reviews,and has a good case to protect it- just seems like a good package for me.

From a financial standpoint- had I stayed with an AGM battery, I'd have gotten a Scorpion ytz7s for $38 (shipping included) from batterystuff: http://www.batterystuff.com/powersports-batteries/sYTZ7S.html
I've used them in the past and had great results... Some in the past have critesized the the purchase of a "cheap" battery- but I never had an issue with that one from batterystuff and they lasted no different than the Yuasa. Much of a battery's reliability depends on the battery retailer's storage and maintinence of their stock... I am just mentioning it for those of use that may not have the extra cash at the time they need a battery.

For the shorai- I might purchase a cheap ($14.99) automatic charger in case of emergency-http://www.rockymountainatvmc.com/p/43/53/160/710/-/24745/Tusk-Battery-Charger-with-Auto-Shut-Off/TUSK+1+AMP+BATTERY+CHARGER
Which is safe for these Lifpo4 batteries- and can be used on my other batteries.

I will concider the Shorai Charger at $80, but we'll see. That charger appears only usefull for the Shorai brand- so I have to see If I'll commit to Shorai enough to buy that too.

The Earth-X brand has cell management (in a microprocessor) to balance charging issues like you mention and allows usage of standard (non-special) chargers.
 
(shorai apparently has some internal circuitry as well that balances the cells- learned this upon further examination)

Got my Shorai LFX14L2-BS12 an installed with a piece of the included foam on the bottom, back, and front of battery (visible in pic).
I used velcro on the back fender and the back of the battery- then ran this velcro strap across the front. (purchased from Ace Hardware)

I started the bike- (don't get excited, that's supposed to happen, nothing magical there)
I tested the running voltages at idle and at 1/4 throttle. Seemed a bit high- considering all this talk about desufication/high volts/ and damage.
In the end no worries, all is well: I got further info from BRP, Shrorai, and a 2nd opinion from Cafehusky. <more info on that here>

This battery does what it supposed to- starts the bike (no different than before) my bike started perfect before and still does. Until, my original YTZ7s died, hense the replacement.
I did like that now my battery does not support the seat- original design with stock battery. The shorai is short enough to clear the seat pad that was supposed to keep the battery in its place. That old system worked for me- but it seemed illogical that the battery should be a support structure holding the seat and the weight of my behind. Now it is only supported by the cross bar on the subframe.

These batteries are definitely lighter, quite noticably so. But can you tell once its mounted? I truly believe I could notice it in tight woods, fast direction changes. It was more flickable. Was that in my head? I don't think so, I immediately forgot about this 'upgrade' once installed and just concentrated on riding. There were no big bling signals saying an upgrade might exists. BUt my bike reminded me of the feeling I was a bit jealous of when I road my buddy's 11TE310. The ability to change directions and manipulate the bike's weight and balance was that noticeable. I am not saying a battery changes my 09TE450 into an Xlite. I am saying loosing the weight on top where it counts- is a big step in the right direction. These Lifpo4 batteries are the cheapest way to loose bike weight and in the right place. NICE!


Shorai.jpg
 
Gotta Shorai and left the key in the ignition (turned on!) overnight. Next morning it was completely dead and I didn´t expect it to take a charge. But it only took about half an hour on the charger to come to life. No probs since then. Amazing!
 
I agree with the Shorai users. I had mine a year on a ATK 605, the bike stalled on the trail and i spent almost an hour trying to restart. when I got my TE 449 I swapped the batteries and found it was dead and would not charge. it had been a year and I had no receipt. I wrote Shorai wondering what my options were, as I had dated the box when I installed it (but no proof). A few days later a new battery came in the mail and I was floored. All they wanted was for me to send back the old one so they could figure out what happened. AWESOME service I will not buy anything but Shorai. Now a Shorai user for 18 months.
 
EarthX is superior to Shorai, stronger outer case, no special charger needed, balances the charge to each cell and cannot be damaged from over charging/discharging. Designed and manufactured in the United States.
