Hi Sonny,
You can purchase the can-am X3 MAX Dual Battery Kit with an Odyssey PC925 battery. We sell the batteries separately as some people either get their own batteries or want to choose between Odyssey and Full Throttle.
If you want to also upgrade your factory battery you need to purchase the X3 Factory Battery Upgrade Kit and an Odyssey PC925L or Full Throttle FT410R.
**please note: the Dual Battery Kit uses a PC925 or FT410 BUT the Factory Battery Upgrade Kit needs a PC925L (reverse post) or a Full Throttle FT410R (reverse post)
