Battery upgrade

[Trimmer]

Hi
I just purchased a Emio monstercycle for my work commute, it is a 5 mile ride one way, I'm not able to charge the scooter at work, so I'm looking for a battery pack that will give me a longer range the pack that came with it is 60v/12ah what should I do

IMO doesn't look like a good commuter. Where is the battery at?

Just got home from work,there and back 11 miles and only used one of four bars, so it was the first time using the scooter, so I don't think it was fully charged when I test rode it,
the battery is along the bottom of the scooter, 4 inches tall 10" wide and 2 foot long metal box along the bottom where feet go, plenty of room for bigger batteries, it gets super hot in phoenix az so we will see how it holds up
but I am looking at a 60v/60ah
