Lithium is fine, just make sure it’s a reputable manufacturer - I think Ducati use Skyrich batteries, and make sure your r/r is a series mosfet not a shunt mosfet. Again, Ducati’s current r/rs are, or buy a 3rd party r/r that’s suitable for use with Lithium batteries from the lies of Ultimate Rectifier or Rick’s Cafe Racer - (both unfortunately in NL).
Talking about batteries Paul, what was the charge pack you used in Scotland please? My Supersport battery's flat in the storage unit and I don't have access to a plug there.
