They do. A solid AGM is ~12.7v max. Lithium is ~13.3v. Times and technology are changing fast in the Lithium world. Cold start is mostly a thing of the past, and CCA is through the roof along with a restart button (on the ones I offer) if you leave the key on, as they have a circuit board that shuts off voltage as needed and they'll also shunt over-charging; https://gtmotocycles.com/collections/electronics/category_batteries?sort_by=best-sellingDo the Lithium batteries have any advantage in terms of static voltage level? I believe they sit at a slightly higher level than lead-acid batteries (at least that's the impression I got via google) and thought it might be a plus when considering voltage drop/voltage level at the ECU on our machines.
