I don't think 22/86 is that obscene of a ratio and I think most if not all their packs are rated to be able to handle any amount of power a Pede could draw so in my "un"professional opinion that wouldn't be it. But 30 cycles in more than a year is not that much really and they suggest if storing for more than a week I think to keep it around 60% charge to keep that from happening. If you let it sit for weeks/months without cycling that is probably the culprit.

But they do offer a 3 year warranty so if you're the original purchaser and picked that up (they offer it free now!) you should be able to get a new pack at a nice discount.
