Yes I'm curious.  To keep my bike batteries happy I have a 4 bank Battery Tender constantly blinking at me and feeding them juice while they sit and wait for freedom.  Thus far it has really served to extend the replacement intervals but I just bumped across a company offering a Lithium-Iron battery for bikes. 

http://www.shoraipower.com/default.aspx

I've seen lithium take over most other battery applications but this is the first I've seen for a bike.  For my BMW F800GS they tout that it's 7.33 lbs lighter than the  lead acid equivalent.    Huh? 

Here's the data for the Shorai battery.

Voltage (V):12

A/Hr PbEq:14

Cranking CCA (A):210

Weight (grams):830.00

Weight (lbs.):1.83

Max Charge (A):14

MSRP: $153.95

 

Here's the data for the Yuasa battery.

Battery Type: YTX14-BS
Voltage: 12

C.C.A.: 200

Metric Weight: 3.7 kg

Weight: 8.1 lbs.

Retail Price: $101.41

 

So ... has anybody heard of these guys or better yet ... tried one of these new-fangled units yet?

I haven’t seen these Shorai batteries, but I was looking at another brand of Li Battery at Ballistic Performance. In addition to being extremely light weight, some of these batteries are half the size of the stock battery too. I was thinking that could create some hard to find room for a nice fuse block in the battery compartment to power accessories. When it’s time for a new battery I’m heading in this direction.

Why did my Shorai battery go dead?   Haven't ridden the bike in several weeks. Thought the battery wouldn't drain.  Have been told you couldn't put  a battery charger on it.  So how do you keep it up?

Shorai batteries will self discharge over time.  However, they self discharge slower than lead acid batteries.  Your bike might have a slight load on the battery which will discharge the battery in a few weeks.  My parked DRZ pulled a small amount of current all the time.  KTM and KLR no problem.

You can charge your Shorai with a Battery Tender type charger, but don't leave the charger connected in trickle or desulfate mode.

Randy, I'd suggest you buy a Corbin seat for your bike..See this thread for further explanation.

Randy,

You can check the remaining capacity of your Shorai battery by measuring the no-load voltage. 

13.5 to 14.2 volts is close to full capacity.  Any reading below 12 volts is nearly dead and the battery should be charged with a Battery Tender type charger.

You Guys 

I have a battery tender. Not sure if it it "trickles or desulfates"!

I'll try it if you sure it wont hurt it!

The Battery   that is!

Cant do anything about the other trickling.

 I shared this with Bert a while back and thought I'd throw it our here.  The guy who made this video is a BMW mechanic and on the 800GS forum is a wealth of real world info.  Thus far he's riding a line that sometimes puts him at odds with his company but most of his answers lend themselves to the real world instead of the lawyer mandated company BS. 

 

 

Of course your mieage may vary.  I am not taking a side on the battery tech evolution wars just yet but it's certainly good to see the experiences instead of living them for a change.

That is interesting. WAS that a Shorai Lith-Ion battery? He said he could hear the battery acid boiling. Does the Lith-Ion battery have battery acid in it?
I dont know....

 If it is a Lith-Ion battery then this test is not good for them.

Randy, Just get an AGM sealed battery and dedicate yourself to a battery tender. There ain't nuthin' that's gonna fix the problem of a DRZ400 from dddddraining the bbbbbattery. David and I have discussed an on/off battery switch like a boat to isolate the battery from the electronic computer / clock on the DRZ400.

I found these guys through amazon.com (blue grass wholesale) aka: bluegrassbatteriesandelectronics.com

I got an AGM YTX14BS equivalent 200cca (stock spec) with 2 year warranty for $40 + 10 shipping compared to mostly 70 to 90 plus shipping or sometimes free. This was for my Triumph which until now has not had the tender on it.

I'm ok with it now that i know i can put my charger on it. I was under the impression you couldnt put a charger on a Shorai. I have always put a charger on it before when i had an acid battery installed. 

Should I say maintainer instead of charger.

Anybody with a DRZ and it's appetite for batteries should do this mod.

 

http://www.sisnerosspeedworks.com/dr-z400-super-start-kit

 

I did it prior to the Idaho ride and have never looked back.  Granted, my bikes live on a charger when sleeping in the garage also.  This mod uses a battery from a CBR 1000 so you know it's got enough oomph for your little thumper,
