So I can only ride until the battery dies (I've figured out how many miles I can go on a full charge). So my hope is that I can ride longer on a bigger battery than a normal scooter battery.

If your headlight is on all the time it will drain the battery faster so you should disconnect it and refrain from running at night of course. Also refrain from using the electric start but remember kick starters are designed for emergency use so are kinda flimsy so their use should be limited.

Yes the tender is a charger and you would have to wait hours for a charge if your battery dies while out riding. Better to have a spare battery.

Repair your charging system soon, do not put it off. Just friendly advise.

I had charging issues with my 150cc, TaoTao.
It turned out to be the Regulator/Rectifier being wired incorrectly.
With a full charge, I would get a while of use, before the brake lights, tail lights, and starting would take it's toll. Recharge, start over.
I checked the stator and replaced the R/R. with no change. My suspicion was no charging voltage, verified at the battery with bike running.
I made short jumpers and moved the connections around until I had charge V, and bright lights (another problem that I really hadn't noticed).
Since then, I never had a charge issue again for 1.5 years; just sold the bike, still good.
I know you didn't want to hear solutions, but this was monumental to me.
