From a recent question regarding a bigger battery to possibly cure an issue with these big scoots...
I don't know how hard it is to measure the battery box on your big scooter, or to see what you have in there for a battery.
I took out my battery, measured it, measured the space it fits in - then went to this YUASA site to see what my battery specs were - and what I could up-grade to that would still fit the space in my scooter. Found this more powerful one that fit with just a quick trim to the battery hold-down pins on the battery cover.

There was nothing listed for my scooter - I just used the info from my OEM Yuasa battery and searched out same sized one with more grunt. Back and forth to my scoot to make certain the new battery would fit - then ordered it from Amazon. Do some reading there and hopefully you can find a more powerful battery that will work in your scooter.
