Ballistic Performance 8 Cell EVO2 Battery
Best bang for the buck for losing weight on your bike. It also only loses a few percent of the charge sitting stagnant over a year period. So its pretty legit. Ive got one in both my bikes.

Ballistic EVO2 12 cell - 2 year review.
I've owned 2 Ballistic EVO2 12 cell batteries now over 2 years. Both were used in my Triumph Sprint ST 1050, which is NOT an easy bike to crank over. I've had at least 3 Pb cells that when they start to age cant turn it over when they are anything but fully charged.
Battery 1: I received the first battery mid summer in prep for a big motorcycle ride. I used it for a 2600 mile trip through the mountains and desert. Weather swings were from 112F mid day one day, and 25F on another depending where I was. The battery performed flawless in all cases.
After that ride, and the months that followed, I noticed a fairly consistent drop in voltage and found the charging system was crapping out. I replaced it, but the battery itself was self discharging at a rate far higher than expected.
After leaving the bike parked for 2 weeks, I came down and found the battery at the 7v Mark, WAY below where it should be.
I put it on a very high end RC charger that can do LiFe chemistry, and checked the internal resistance of the cells. I found one that was super high, and its voltage was 0. So I had a cell go bad.
I called Ballistic and worked out a replacement since I was just a month or so over the first year. They replaced the battery with almost no trouble. Which was awesome! This was an unfortunate issue with a single cell internally that caused the whole pack to start to drain. Which should be an indication of how these batteries may be more fragile than their heavy brethren.
Battery 2: When I got the replacement, there was a clear difference in construction. The Battery 1 felt hollow, and like the cells had some movement room around them. Battery 2 was solid, but still light. I am guessing they are filling the case with something now to keep the battery cells immobile.
I have had this battery for almost a year now, and just put it on that same charger again. After sitting for a month on the bike, the voltage dropped about 1V to 12.5, I checked the cells and they were all within .3v of one another after a year of use between balancing. My bike has a bit of a vampire current draw on it from some electronics I have on the bike, so the voltage drop isn't surprising. But I know I can leave the bike easily for a month and still have it ready to go, or disconnect it and it will be solid for a good long time.
Only issues I have with the battery is I needed to break and peal back the black plastic protectors around the screw lugs to get the wires to attach solid. Not a big deal. Otherwise, its small, light, ready to go all the time, and consistent in any temp I use it in. I know it's slow to turn over in the very cold, but it does start once you put a load across the battery to warm it up.
Reason I give it 4 or 5, is because of the failure I had on one of the cells, which if the company didn't stand behind it I wouldn't give this 1 star... But they did and made it right, which is good on an almost $200 battery.

Huge Weight and Space Savings!
Battery power performance seems to be similar to stock battery at the current outside temps of 75 and above. I will come back and review again during the winter.
The huge benefit (what you pay for) with this battery IMHO is the weight and space savings. Shaved probably around 7 pounds off weight wise, but for me I needed more space for some electronic projects. After re-arranging battery cables I ended up with more that half of the battery box free!

Nifty product, indeed.
I went with the recommendations by the ballistic website for my bike and I'm pleased with the acquisition this far. Don't have to worry about placing on a battery tender, fluid spill etc. comes with foam padding that can be used to fill up the extra space left due to the small dimensions of this battery and also decrease vibration. The fact that it's superlight and has a warranty helps too ;)

Works great. I think I might have bought too little of a battery ,but this one will work,, My fault

Died after 4 months
Used on a street xr400 to replace the tired 8-AA bundle that had come with a dual-sport kit a few years back.
Worked fine for a measly 4 months then went to 0 v after a routine charge up (from 10.5 v) & Ballistic shrugged off their 'Industry Leading Warranty' and left me $60 out of pocket.
The irrelevant reasons they gave:
1. Warrantied only if used on a 50 cc scooter
2. Not covered if used as a 'main power source'
3. Warranty void if battery falls to below 30% of operating voltage
.... yep, NONE of the above were even true in my case but I guess they don't want to stand by their product.
Google this battery and you'll see a number of unexplained failures out there too.

10lbs lighter on my ST1300
When I received the product I thought the box was empty. Someone made a mistake at shipping was my response. Holding the battery I wondered if it will do the job. The installation was relatively easy and cutting the foam to shape made the install not difficult. After I finish and saw all the empty space my mind started to come ideas to place more gadgets inside my bike.
On the road. Starting the bike was easier and all my gadgets like the new battery. I also noticed that my mpg increased a bit. 10lbs off makes a difference.
Great product and amazing performance. I am waiting for Ballistic to make car batteries.
