I can tell you that these bikes are finicky when it comes to voltages. Hard starts where pretty common. Particularly warm/hot re-starts. I spent too much time overthinking that it had to be something worse than a battery. Then when you go up to LIon and all problems were solved, I began to connect the dots. The electronics like a good voltage level. It doesn't go much below 12V available before it gets bratty acting. These batteries need a little reserve in them.
