  • 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 The previous version was outdated and no longer supported.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!

BATTERY OPTIONS

Shorai doesn't need a special charger. As long as your charger doesn't have a desulfation mode (or has a way to switch it off), it is okay to use.
 
While standard lead-acid chargers can be used with Shorai LFX when needed, the BMS01 is specifically designed to charge, store, maintain, balance, and diagnose your LFX battery.

The battery management system or BMS for short in Shorai batteries is built into their specialized charger, where as the Earthx contains this charger above it's cells inside each battery. Charge is balanced over each of the cells with a standard charger, where as Shorai currently uses this same technology in their charger.

Shorai Charge and Store Battery Management System which includes STORE MODE for maximum battery life during long-term storage, CHARGE MODE charges, balances, and performs cell diagnostics. Also features a retractable hook to hang from grips, frame rails, or seat straps. Operating Specifications: 100V~250V 50/60 Hz AC Input; 2A max charge rate.

They may have an optional charger with additional functionality, but that doesn't equate to 'needing' a special charger.

That being said, my Shorai apparently died on me last week. I'm charging it now to see if it's a battery problem, or if I have a short somewhere. Couldn't find any current drain when I checked the original battery in my bike on the weekend.

Maybe I'll end up with Earthx after all.
 
I have both a 14ah Shorai in my ktm race bike and a 9ah Ex for my Husky. The Ex out cranks my Shorai and I don't have to worry about draining it down below 10.5 volts. If I drain my Shorai down too low, it bricks it, where as I can go down to 8 volts on the Ex and the BMS circuit shuts off the battery before damage can occur. I bought the shorai before I researched into the Ex. I asked Ty why Ex? He said of all the batteries available, if he had to put his name on one, it was going to be the Ex.

What Earthx do you recommend for a 2013 TE310?
 
I don't really understand why the Shorai batteries need a special charger to 'ballance the cells'
What happens every time you start the motor, it then puts charge into the battery?
Nothing special there, just regular voltage output from the generator.

On a conventional battery, the cells are relatively equal and are maintained at 100% charge capacity. On a rechargeable Li ion battery, the cells are kept at a maximum of 80% of full charge for longer life. Not all the cells are equal and have different charge rates and internal resistances which create elevated temperatures when charging/discharging. The cells need to be constantly monitored using a microprocessor charging system so that each cell may be brought up in equilibrium. On a Shorai battery, this charging system is in the external charger and is not taken with you while you ride. The Ex batteries contain these charge systems on board and are constantly managing the charge rates while you ride.

You could just plug one in and hope for the best. It will work, but you are not likely to receive your 8 year battery life. :)

^ Or in my case, only just over a 1 year battery life.... My Shorai will not charge. I've had it since around April 2012. It was just fine when I rode two weekends ago. This weekend, it wouldn't turn my bike over. As I mentioned, I checked for any draw with my stock battery in case it was draining, and there was none. Had the Shorai on the charger since the weekend, and it has not charged. It sits at around 8.5V. I checked the Shorai warranty, and they would basically give me 50% off a new battery if I shipped my current to them at my expense. So for about $100 I get warranty replacement of a battery that cost me >$150 and lasted just over a year, with light duty. No thanks.

I'd also add that the terminals on the Shorai are flimsy at best. I contacted them about this when I first got the battery, and was told that mine came with the new 'thicker terminals.' It frightens me to think how flimsy they must've been in the previous revision.

For now I'll stick with the stocker and its extra weight, but in the future, I'd consider the Earthx. I will never buy another Shorai.

Thanks for the info, Tinken!

That's my point exactly, if charging is so complicated then the bikes charge system it woefully inadequate, no wonder they fail. The electronics have to be on board the battery for the battery to manage itself

I see your point. Makes EarthX more appealing. Maybe it's like ink jet printers...a profit center idea. How much do the chargers cost? Does it make the price of the EarthX and Shorai pretty close.?
 
The ETX12A retails for 169.99 and we sell it for 153.00 w/CH discount. The Shorai battery charger is about 85 dollars.
 
Got my ETX12A but won't fit the stock tray as shown..... Not quite drop in... Need to figure out how I'm going to mount it.

I went to an 8 cell ballistic, my 4 cell finally failed and was indicated by a very bad running engine FI was acting up big time, They gave me an 8 cell to install and I have never looked back.
this is the 8cell installation, there is a little more, I added insulating rubber on the cross member and stuffed some high density foam between the cross over and the top of the battery, but you get the idea. Note I used the oem tray and filled the space with hi density foam then long zip tie the thing in place using the all ready built in dran holes in molded in fender ribs. This can be used with other battery types as well, this set up has numerous hard core rides and races on it with no issues. I also installed a slit rubber vacuum hose over the top lip of the molded inner fender batter shelf after seeing it with dirt start to work into the battery base.
 
EarthX has bigger terminal bolts than Yuasa. Had to put larger diameter connectors on my Trail Tech wire to these terminals.

Think I had a similar issue when I added a Turn-tech lithium to my 2008 TE 250.
