While the luddites are still on their way with their Yuasa steam locomotive my recommendation is any modern LiFePO4 battery with an integrated BMS. Lightweight, huge CCA. I ran a Shorai for 5 years (no onboard BMS) and then switched to a Fulbat. Running another Fulbat on my Hypermotard now.
A good quality AGM lead acid chemistry battery is less affected by periods of inactivity than a lithium chemistry battery. Yes LiPo/LiFe deliver higher CCA (cold cranking amps) but they struggle to deliver the increased CCA if the overnight ambient temperature has been chilly. Charging voltage for a lithium chemistry battery must not exceed 14.9V, the battery charge must not fall below 11.7 volts or you risk failure and lithium chemistry batteries do not like a steady current drain from something like a tracker or aftermarket alarm. My Panigale V4 came with a LiFe battery, it has a tracker and I’ve used a good quality specific battery maintainer for 3 years without issue. My Multistrada has a Yuasa AGM lead acid battery, no issues and by no means out performed by the lithium battery. If you are happy to spend the increased retail price and buy a decent battery maintainer, no reason not to go lithium. If you leave the bike for long periods without a maintainer fitted, I’d disconnect a lithium or buy an AGM. Andy
LiFePo4 all the time for me. Takes 5 minutes to charge it up. It’s light and will take many more charging cycles.
