No, the battery is brand new and has never failed on me. I was looking for first hand experience from others who have taken their Shorai batteries through water crossings. I'm not as concerned with the battery now that it's sealed with silicone, but only time will tell if it can withstand mud, water, vibration, temperatures, and heavy amp draw from the big 990 with accessories. Based on your and Zeegman's feedback, I'm confident the Shorai should be OK long-term. If I can get 3 years of abuse out of it, that will be acceptable to me.
IMO, Shorai should release a sealed "ruggedized" version of their batteries for powersports applications. Maybe they will in the next few years...
