I had a few of the early lithium batteries, they weren't great. combined with the old 'startus interruptus' issues, I can see how someone working on guzzis in that period could come that conclusion. the new batteries are vastly improved though, those problems are in the past.I would think but I'm no expert. Everyone talks about Cadre in high regard so I'm rolling with what they are saying. He said he would do a diagnostic but believes it sounds like a straight battery swap to solve from what I described over the phone.
