Shorai batteries

So I went into a new MC accessory shop yesterday to scope out their offerings and liked what I saw. At one point I engaged the store manager in a discussion about MC batteries given that my BMW RT's battery went south last week - almost exactly three after it was replaced. This has been my experience since I bought the bike new; battery goes bad every three years. He pitched me on Shorai, a lithium type battery as the shiznit of all batteries.

I did some due diligence and discovered that these batteries are above average but lacking in performance when the subject bike has accessories. My RT has a 700 watt alternator and some accessory features both factory and aftermarket.

I'm wondering if anyone else out there has any feedback to offer about lithium batteries in general and Shorai in particular.

I have had a Shorai since December 15, 2011 and it performs quite well. I also use their maintainer. You have to learn to use it by turning your headlights to warm the battery up before starting when cold.

Have a Shorai in both bikes. No problems yet. They have survived a couple periods of winter storage with only the ST4s being kept on the dedicated tender due the constant draw of the clock and immo. The 916 is just left as is. When that bike is off, it's really off. They have a very good initial capacity to start your bike quickly and they weigh nothing.

I do feel they (the technology, not Shorai) have some drawbacks and I would probably not use one in the ST if I were going to tour on it. The way they have just dropped off for some people without warning, sensitivity to over or under performing charging systems, the apparent lack of deep capacity for those times your bike may not want to start right away or the potential for catastrophic meltdown. These problems seem to be more infrequent as the technology matures, especially if you stick to the name brands and not source a bargain battery somewhere.

They weight difference between the Shorai and AGM or Lead Acid batteries is shocking. You pick one up and it feels like one of those "display" batteries you sometimes find a shops, just an empty shell.

I was definitely not an early adopter, but I am coming around. I still feel they don't belong in something like an ST if you're going to use it for multi-day trips far away from home. I have no rational reason to have that opinion, as long as your bike is working well, and I guess it would need to be no matter the battery if you're going to use it on a long trip!

Regarding accessory loads. Not somthign I personally deal with, but if you are not exceeding your generators's disposable capacity, as in what's left over after accounting for the bike's electronics and need to keep the battery charged, then I can't see where it would be any problem at all. If you exceed the capacity of your generator, I don't think the Shorai would handle the constant draw very well.

Good feedback. Yes, the weight difference is incredible and most appealing but the thought of having the electrical/charging system crap out on me in the middle of no where has me concerned.

I've been taking the ST3 out on ever increasing distance rides with the thought of doing a multi state trip. Some members here may laugh at my trepidation but let's face it, there ain't many Ducati dealers out here nor much of a support system if a bike breaks down on the road. The bottom line is that I need to learn the bike and make sure it's in the best shape possible before heading out. That means using quality parts and components.

I've been pretty interested in the EarthX units. They seem like Shorai's with extra brains.

Plus the fact they can use many other chargers means I won't have to buy a specialized one and bin my current one.

The Shorai is about $100 less than an EarthX, buy a Battery Tender Jr / Lithium for $30.

I put in a Shorai last year. I use the trickle charger to keep it up Now I don't leave it on overnite and don't fully charge it. Bike is inside in a heated garage I have started it during our LONG winter and works very ok. I left bike outside in a covered trailer for weeks in the cold weather and no problemo starting after 3 weeks.

Batteries have come a long way hoping it lasts as long as a stock battery did 6 Years, The stock battery is my emergency back up battery and powers the inside trailer lights .

Now if the Shorais were crap the net would be overloaded with people crying the blues about them.....???
Bragging rights about how little your battery weighs is a bonus.

I've been using them for quite some time, in two Ducs, one MV and an RSV4. It's all I'll use anymore.

Goodbye RSV4 and MV Agusta. Back on a Duc.

Could you give us a bit of detail on your experience? Did you have multiple failures? How was it maintained? Did you use it on an ST? In the winter? Daily rider?

I have been holding off as my ST is a commuter that sees temps down into the mid-20F in the winter and sits outside at work during the day. In a decently warm garage at night. So, I have been holding off on the LiFePO batteries until threads like this can answer those questions, esp when there have been failures.

Also, how did Shorai treat the failures?

Have a good one.
