Well my Ballistics EVO-2 eight cell has died. It is literally 2 years and 5 days old to the date of purchase, and it won't hold a load and dumps from full charge to 9volts as soon as a load is applied. I have tried charging it on a "full size" bench charger at 12amps, then dialed off to 2amps and left to maintain for a week. Still drops charge immediately, and won't come close to cranking over a engine .... even the little 200cc BW200.
I contacted them about there "industry leading warranty" and they told me that I would need to box it up, ship it back to them in the states and they would assess it for customer damage and miss use prior to agreeing on the claim.
I explained the scenario and the gave them a few voltage numbers and they told me that I shouldn't have let the voltage drop to 9V under load ...... not much you can do about that if when you press the button it drops like a stone.
There "industry leading warranty" is pro-rated so the best I will get is 50% off the retail price towards the purchase of a new battery .... plus covering the shipping both ways.

I will not be getting another one and will be swapping back to a AGM YTZ10S oem style battery, since I can get one locally for a good price.
Honestly I have never really been happy with my EVO-2, it needed to be tricked charged after the first season constantly since they have a weird cold start procedure and when you combine that with a PC3 on a 919 it makes the bike VERY hard to start.
It is a neat battery, cool design and crazy small and light ...... great for a track application or maybe a cafe/brat/bobber build where you are looking to tuck and hide the battery. I might get one for some future projects, preferably something with a kick start back up. Haha.
Maybe I just got a crappy one, but with only receiving 50% off the next purchase price I certainly won't be going through this all over again.
